Tower Semiconductor InP Wafer Deal Secures AI Photonics Supply

iQE

Tower Semiconductor InP wafers will be supplied by UK-based IQE under a long-term agreement supporting next-generation optical connectivity products for artificial intelligence data centres. The deal strengthens Tower's access to indium phosphide epiwafers as demand for high-speed photonics accelerates.

Tower Semiconductor InP wafers will be used across several silicon photonics platforms, including technology for 200 Gb/s per lane optical transceivers and prototype 400 Gb/s per lane modulators. These components are designed to handle the rapidly increasing data requirements of AI training and inference systems.

Tower Semiconductor InP wafers have become strategically important because AI data centres require faster connections between servers, switches and accelerators. Indium phosphide is particularly suited to lasers and modulators operating at optical communications wavelengths.

The agreement includes minimum purchase commitments from Tower and reciprocal supply obligations from IQE, giving both companies greater visibility as they prepare for higher production volumes.

AI Data Centres Accelerate InP Photonics Demand

AI infrastructure is pushing optical networking requirements beyond traditional telecom applications. Larger computing clusters need higher bandwidth while also reducing the amount of electricity consumed moving data between processors.

InP plays a central role because it can efficiently generate and manipulate light for high-speed optical transmission. This makes it valuable for lasers, modulators and other photonic devices integrated with silicon-based platforms.

Tower plans to use IQE material for 200 Gb/s per lane pluggable transceivers and is also developing 400 Gb/s per lane modulators. Optical circuit switching represents another potential application as hyperscale data centres seek more efficient network architectures.

Commercial commitments are already building around Tower's expansion. The company has signed $1.3bn of silicon photonics contracts linked to 2027 revenue and received $290mn in customer prepayments to reserve production capacity.

These figures highlight how optical connectivity is becoming a major infrastructure bottleneck alongside processors, memory and power supply.

Supply Commitments Highlight Tight InP Capacity

The agreement is also important because global InP wafer availability remains constrained. IQE has been working with multiple suppliers to secure enough material as semiconductor manufacturers compete for capacity.

The minimum volume commitments give IQE a clearer demand base for future investment while providing Tower with greater supply certainty.

IQE recently secured investment and purchase commitments from US semiconductor manufacturer Macom, helping the company avoid a potential sale and reinforcing its position in the compound semiconductor market.

As hyperscalers such as Amazon and Google continue expanding AI infrastructure, more semiconductor manufacturers may seek long-term contracts to secure InP supply.

The Tower-IQE deal therefore reflects a broader shift in the semiconductor supply chain. Access to advanced materials is becoming as strategically important as chip fabrication capacity itself.

Under a separate agreement, Tower will also provide IQE with a worldwide royalty-free licence covering porous silicon patents, resolving previous intellectual property litigation between the companies.

The Metalnomist Commentary

InP is moving from a specialist telecom material into a core AI infrastructure input. As optical bandwidth requirements rise, long-term wafer supply agreements could become increasingly important to securing semiconductor capacity.

China Strategic Minerals Framework Tightens State Control Over 36 Resources

Strategic Minerals

China strategic minerals policy has entered a more formal phase after Beijing placed 36 mineral resources under tighter central government control. The revised regulations strengthen state oversight of mining, exploration, production quotas and strategic reserves.

China strategic minerals covered by the framework include major industrial metals, battery materials, rare earths, semiconductor metals and energy resources. The rules also include non-metallic materials such as graphite, phosphate, fluorite and high-purity quartz.

China strategic minerals regulation is significant because many of the affected materials are essential to batteries, aerospace, defence, semiconductors, energy infrastructure and advanced manufacturing.

The immediate market impact has been limited because several controls already existed in practice. However, formalising them under a single legal framework could strengthen Beijing's ability to manage supply over the longer term.

Centralised Quotas and Reserves Strengthen Supply Management

The Ministry of Natural Resources, working with the National Development and Reform Commission, will set annual mining quotas for strategic minerals.

The objective is to prevent uncontrolled production while giving central authorities greater control over national resource development.

Approvals for new exploration and mining rights will also be consolidated at the central level. Authorities will restrict the number of mining licences granted for individual deposits.

This could slow uncontrolled capacity growth in some markets while giving Beijing more influence over production timing and regional development.

The new framework also establishes a three-tier reserve system covering physical product inventories, production capacity and undeveloped resource sites.

State and private companies will jointly participate in stockpiling, while resource-site reserves are expected to remain available for at least five years.

This creates a broader security mechanism than conventional commodity stockpiles. China will not only hold material inventories but also preserve future production capability and undeveloped resources.

For strategically sensitive metals, this could provide Beijing with greater flexibility to respond to supply disruptions, price volatility or geopolitical pressure.

Rare Earths and Semiconductor Metals Gain Greater Strategic Weight

The list covers 25 metallic commodities, including iron, copper, aluminium, titanium, vanadium, manganese and chromium.

Battery materials such as lithium, cobalt and nickel are included alongside all 17 rare earth elements.

China has also designated tungsten, antimony, tin and molybdenum as strategic resources, together with semiconductor and specialty metals including gallium, germanium, indium, rhenium, niobium, tantalum, beryllium, zirconium and hafnium.

This combination is important because China already holds dominant positions across many of these supply chains.

Rare earth separation, tungsten processing, antimony, gallium and germanium are particularly sensitive because alternative global processing capacity remains limited.

The inclusion of high-purity quartz also highlights the expanding definition of strategic materials. Quartz is an important input in semiconductor and solar manufacturing, linking mineral security directly with advanced technology industries.

The framework therefore goes beyond mining policy. It strengthens China's ability to manage the upstream materials required for manufacturing competitiveness and national security.

The Metalnomist Commentary

China is moving from individual export controls and quotas toward a comprehensive strategic resources system. The long-term implication is greater state influence over not only current supply, but also future capacity and undeveloped reserves across many of the world's most critical materials.

Alpha HPA Supply Deal Targets South Korean Battery Materials Market

Alpha HPA

Alpha HPA supply deal plans have advanced after the Australian producer signed a non-binding agreement to supply 5,000 t/yr of high-purity aluminium products to a South Korean lithium-ion battery manufacturer.

Alpha HPA supply deal development follows qualification work with a tier-one battery anode producer evaluating ultra-high-purity aluminium nitrate for next-generation synthetic graphite anodes. The agreement strengthens Alpha's exposure to the battery materials market alongside semiconductor demand.

Alpha HPA supply deal volumes also push the company's total committed volumes under binding agreements and letters of intent to 12,350 t/yr, up from 6,900 t/yr in March.

Crossing 10,000 t/yr of committed volumes is particularly important because it satisfies a condition linked to Australian government-backed financing for the company's planned large-scale Gladstone facility.

Battery and Semiconductor Demand Support Gladstone Expansion

Alpha plans to develop a second-stage plant in Gladstone, Queensland, with 10,930 t/yr of production capacity.

The company expects the facility to begin production in the second half of 2027, although a detailed construction timetable has not yet been disclosed.

Government financing could help accelerate the project. Alpha has access to up to A$400mn in loans through Australian infrastructure and critical minerals financing programmes.

The company now plans to target debt drawdown during the second half of 2026 after surpassing the required 10,000 t/yr threshold for customer commitments.

Alpha already operates a smaller commercial plant in Gladstone producing high-purity alumina, alumina trihydrate and aluminium nitrate.

The new facility will be necessary to support larger customer volumes because existing production capacity is far below the level required under recently signed agreements.

The South Korean battery agreement also demonstrates that high-purity aluminium compounds are moving beyond traditional ceramic and industrial applications into advanced battery materials.

Ultra-high-purity aluminium nitrate can support specialised treatments and coatings used in next-generation synthetic graphite anodes, increasing the importance of purity and contamination control.

AI and Battery Markets Create Dual Growth Path for HPA

Alpha expects demand for its products to rise from around 20,000 t/yr this year to nearly 60,000 t/yr by 2030.

Battery materials represent one growth route, but semiconductor manufacturing is becoming equally important.

South Korean and Japanese manufacturers of semiconductors and high-bandwidth memory chips are increasing demand for high-purity materials as artificial intelligence data centres expand.

Alpha converted a previous 1,000 t/yr HPA letter of intent into a binding supply agreement with a South Korean HBM manufacturer earlier this year.

This gives the company exposure to two rapidly growing technology markets: lithium-ion batteries and AI semiconductor infrastructure.

Australia designated high-purity alumina as a critical mineral in 2022 and has since provided Alpha with grants and direct investment alongside loan support.

The industrial objective is clear. Australia is attempting to move from mineral extraction toward higher-value specialty materials that can enter Asian battery and semiconductor supply chains.

The Metalnomist Commentary

Alpha's strongest advantage is its exposure to both batteries and AI semiconductors rather than one single demand cycle. If Gladstone reaches commercial scale, HPA could become another example of Australia moving successfully from raw materials into advanced specialty processing.

Japan Aluminium Extrusion Merger Brings Nippon Light Metal and Kobe Steel Together

Nippon Light Metal

Japan aluminium extrusion merger plans will combine the domestic extrusion businesses of Nippon Light Metal and Kobe Steel as both companies seek stronger competitiveness in a weaker demand environment.

Japan aluminium extrusion merger is expected to create a joint holding company from April 2027 or later, with Nippon Light Metal holding a majority stake. The companies aim to sign a definitive agreement by the end of November 2026.

Japan aluminium extrusion merger will combine businesses selling roughly 58,000 t/yr in total. Nippon Light Metal’s unit handles around 30,000 t/yr, while Kobe Steel’s Chofu Works sells about 28,000 t/yr.

The integration will bring together Kobe Steel’s alloy development expertise and Nippon Light Metal’s processing technology and wider customer base across transport, machinery and industrial markets.

Combination Targets Cost Cuts and Stronger Automotive Position

Kobe Steel’s aluminium extrusion business has faced weaker earnings as orders declined, prompting the company to consider partnerships as part of its long-term restructuring.

The merger gives both companies an opportunity to consolidate overlapping functions and improve capacity utilisation.

Kobe Steel brings particular strength in automotive components, railway applications and alloy development. Nippon Light Metal contributes a broader order base spanning transport equipment, industrial machinery and containers.

Combining these capabilities could strengthen the new entity’s position in higher-value extrusion markets where alloy performance, precision processing and customer qualification are important.

The companies also plan to standardise capital investment across the combined business. This should reduce duplicated spending and allow equipment upgrades to be prioritised across a larger production network.

Cost reduction will be especially important as Japanese aluminium processors face pressure from weaker domestic demand and global competition.

Scrap Collection Becomes Part of the Integration Strategy

The companies also plan to improve aluminium scrap collection through the combined business.

This is strategically important because recycled aluminium can lower both raw material costs and carbon intensity compared with primary metal.

A larger extrusion platform can generate more internal process scrap while also strengthening relationships with external scrap suppliers and customers.

Better scrap collection could support closed-loop recycling arrangements, particularly in automotive applications where manufacturers increasingly seek lower-carbon aluminium.

The integration therefore extends beyond conventional consolidation. It could help the companies build a more efficient material cycle linking billet casting, extrusion, processed products and scrap recovery.

The new entity will cover Nippon Light Metal units including Nikkeikin Aluminium Core Technology, as well as Kobe Steel’s extrusion, billet casting, processed products and domestic sales operations at Chofu Works.

The Metalnomist Commentary

The merger shows that Japan’s aluminium extrusion sector is entering a consolidation phase driven by weaker demand and cost pressure. The strongest strategic upside may come from combining alloy technology with better scrap recovery and higher-value automotive applications.

Rapidus UK Semiconductor Centre Partnership Deepens Japan-UK Chip Cooperation

Rapidus

Rapidus UK Semiconductor Centre cooperation is expanding after the Japanese chip developer signed a memorandum of understanding with the UK Semiconductor Centre to strengthen advanced semiconductor manufacturing ties.

Rapidus UK Semiconductor Centre collaboration will focus on exchanging information and views on advanced chip technology, manufacturing ecosystems and industry development. The agreement comes as Rapidus advances its Hokkaido pilot line toward mass production of 2nm logic semiconductors.

Rapidus UK Semiconductor Centre partnership also fits a broader Japan-UK push around economic security and supply chain resilience. Both governments are placing greater strategic importance on semiconductors, critical minerals and advanced manufacturing.

The cooperation extends beyond chip fabrication. Japan is simultaneously seeking more resilient supplies of rare earths and other strategic materials needed across semiconductor equipment, electronics and high-technology manufacturing.

2nm Development Strengthens Japan-UK Technology Links

Rapidus is using its Hokkaido pilot manufacturing operation as the foundation for planned commercial-scale 2nm semiconductor production.

That places the company in one of the most technically demanding parts of the global semiconductor industry, where manufacturing capability is concentrated among only a small number of producers.

The UK Semiconductor Centre was established in 2025 to support domestic industry growth and expand international collaboration. Working with Rapidus gives the UK access to a partner directly involved in leading-edge logic manufacturing.

For Japan, cooperation with the UK broadens the technology network supporting its attempt to rebuild advanced semiconductor capacity.

The agreement could also create opportunities across equipment, materials, research and engineering. Leading-edge semiconductor production depends on a complex ecosystem including lithography, specialty gases, photoresists, advanced packaging and high-purity metals.

This makes semiconductor cooperation increasingly relevant to industrial supply chains beyond chips themselves.

Critical Minerals Security Moves Closer to Semiconductor Policy

Japan is also pushing for greater coordination among G7 countries on critical mineral stockpiling.

The proposed framework would create national stockpiling systems and link them across participating countries, improving collective resilience during supply disruptions.

The strategy is becoming more urgent as China increases control over critical mineral exports. Rare earths are especially important for magnets, electronics and semiconductor manufacturing equipment.

Japan is already working with countries including France and Australia to diversify rare earth sourcing and processing.

This creates a broader industrial strategy connecting semiconductors with upstream materials security. Building domestic 2nm capacity has limited strategic value if essential materials remain exposed to concentrated foreign supply.

Japan's approach therefore combines advanced manufacturing investment with allied sourcing, stockpiling and technology cooperation.

The Rapidus-UKSC agreement is another step toward that model, where semiconductor competitiveness is supported by a wider network of trusted industrial and mineral supply partners.

The Metalnomist Commentary

Semiconductor security is no longer only about fabs and chip design. Japan is increasingly linking 2nm manufacturing, allied technology cooperation and critical mineral stockpiling into one integrated industrial security strategy.

Ucore Rare Earth Supply Partnership Expands With Sumitomo

Ucore Rare Earth

Ucore rare earth supply strategy is gaining a major commercial partner after Ucore Rare Metals formed a strategic collaboration with Sumitomo Corporation of Americas. The agreement will support feedstock procurement, separated rare earth sales and market access in Japan.

Ucore rare earth supply development will center on the planned Louisiana Strategic Metals Complex, where the company intends to process rare earth feedstock into separated products. Sumitomo will help secure suitable raw materials and develop offtake channels.

Ucore rare earth supply plans are particularly focused on selected middle and heavy rare earth elements used in high-performance permanent magnets and advanced materials. These elements remain among the most strategically constrained parts of the global rare earth supply chain.

The partnership also strengthens links between North American processing and Japanese industrial demand while preserving material for additional processing in the US and allied markets.

Sumitomo Adds Feedstock and Japanese Market Access

Sumitomo will act as a distribution partner for designated separated rare earth products sold into selected Japanese customer segments and other industrial applications.

This gives Ucore access to an established trading network with experience across rare earth procurement, distribution and downstream customer relationships.

The collaboration is significant because building separation capacity alone does not guarantee commercial success. Rare earth refiners need reliable feedstock on the upstream side and qualified buyers for separated oxides on the downstream side.

Sumitomo already has experience building such supply chains. The company became the exclusive distributor of neodymium-praseodymium oxide produced by MP Materials in 2023.

It also established Summit Atom Rare Earth Company in Kazakhstan to produce rare earth materials containing dysprosium and neodymium.

That platform now connects African feedstock, Kazakh processing and Japanese technology through relationships with Lindian Resources and Shin-Etsu Chemical.

For Ucore, Sumitomo therefore brings more than distribution capability. It brings an existing international network spanning mining, separation and magnet-related markets.

Heavy Rare Earths Strengthen Allied Supply Chain Strategy

The partnership's focus on middle and heavy rare earths is strategically important because these materials remain highly concentrated in Chinese supply chains.

Dysprosium and other heavy rare earths are critical for permanent magnets that must maintain performance at elevated temperatures. They are widely used in electric vehicles, defence systems, aerospace and advanced industrial equipment.

Ucore's Louisiana facility is intended to provide an alternative separation route for these materials in North America.

Securing feedstock from multiple jurisdictions will be essential. A processing facility without diversified raw material supply can simply replace one dependency with another.

The Sumitomo partnership addresses that risk by combining sourcing, processing and offtake development across allied markets.

It also reflects a broader shift in rare earth strategy. Governments and companies are increasingly building interconnected supply chains across the US, Japan, Australia, Africa and Central Asia rather than relying on individual national projects.

If Ucore successfully commissions the Louisiana complex, Sumitomo's commercial network could help accelerate customer qualification and reduce market-entry risk.

The Metalnomist Commentary

Rare earth security increasingly depends on linking mines, separation plants and customers across multiple allied countries. Ucore's partnership with Sumitomo is strategically valuable because it addresses both sides of the processing bottleneck: feedstock supply and downstream market access.

USAR Rare Earth Separation Plant Starts Operations in Colorado

US rare earths

USAR rare earth separation capacity has taken another step forward after USA Rare Earth commissioned its hydrometallurgical demonstration plant in Wheat Ridge, Colorado. The facility will produce separated heavy rare earth oxides, with initial output scheduled for the third quarter of 2026.

USAR rare earth separation will target strategically important materials including dysprosium, terbium and yttrium. These elements are critical to high-performance magnets, aerospace, defence, electronics and other advanced manufacturing applications.

USAR rare earth separation is especially significant because heavy rare earth processing remains one of the most concentrated stages of the global supply chain. Developing domestic separation capability could reduce US dependence on overseas processing.

The Wheat Ridge facility will also test multiple feedstock routes, allowing USAR to process mined material alongside recycled magnet waste.

Three Feedstocks Test a Flexible Heavy Rare Earth Supply Model

The Wheat Ridge plant is designed to process three flowsheets in parallel. These include ore from USAR's Round Top project in Texas, material from the Serra Verde Pela Ema mine in Brazil and magnet swarf from manufacturing operations.

This diversified feedstock strategy is strategically important. A separation facility capable of handling both primary resources and recycled material can reduce dependence on a single mine or supply route.

Round Top provides a potential domestic US feedstock source, while Serra Verde gives USAR exposure to Brazilian heavy rare earth resources.

Magnet swarf adds a recycling pathway. Manufacturing waste can contain valuable neodymium, dysprosium, terbium and other rare earths that can be returned to the supply chain instead of being discarded.

The combination creates the basis for a more circular rare earth system connecting mining, recycling and downstream separation.

The plant's automation and real-time process monitoring should also generate technical data required for commercial scale-up. In rare earth processing, consistent purity, recovery and process control are essential before technology can move into large-scale production.

Federal Funding Supports USAR's Integrated Rare Earth Strategy

USAR has secured access to as much as $1.6bn in US government funding, providing significant financial support for its wider rare earth strategy.

The company is attempting to build an integrated supply chain extending beyond mining into separation, metals, alloys and permanent magnets.

Its planned acquisition of Serra Verde would further strengthen that structure by adding an operating Brazilian heavy rare earth resource. The transaction remains subject to regulatory scrutiny in Brazil.

Heavy rare earths are especially important because dysprosium and terbium are used to improve the temperature resistance of NdFeB permanent magnets.

These magnets are critical to electric motors, defence systems, robotics, aerospace and other high-performance applications.

For the US, securing access to ore alone is therefore insufficient. Separation capacity is essential because mixed rare earth feedstock must be converted into individual high-purity oxides before downstream metallisation and magnet production.

The Colorado demonstration plant gives USAR an opportunity to prove that capability across several feedstock types before moving toward larger-scale production.

The Metalnomist Commentary

USAR's Colorado plant targets one of the hardest bottlenecks in the non-China rare earth chain: heavy rare earth separation. Its ability to process both mined feedstock and magnet waste could become strategically valuable if the technology proves scalable.

LEO Semiconductor Demand Rises as US-China Space Race Accelerates

LEO chip

LEO semiconductor demand is accelerating as low earth orbit satellite deployment expands and the US-China space technology race intensifies. Greater satellite density is increasing the semiconductor content required for communications, sensing, computing and power management.

LEO semiconductor demand is also creating new opportunities for advanced materials including gallium nitride, silicon germanium and indium phosphide. These materials support high-frequency communications, radio-frequency power, photonics and other functions where conventional silicon can face performance limits.

LEO semiconductor demand is moving beyond traditional government space programmes as private capital enters satellite broadband, direct device connectivity and potential orbital data centres. The shift is increasing launch frequency and expanding the commercial market for space-qualified electronics.

The development has strategic implications for gallium and indium supply chains. Higher deployment of GaN and InP devices could increase demand for high-purity materials already considered strategically sensitive.

GaN and InP Gain From Higher Satellite Semiconductor Intensity

Modern LEO constellations require increasingly sophisticated radio-frequency chips, optical communications devices, sensors and power electronics.

GaN is particularly important for RF power amplifiers because it performs efficiently at high frequencies and power levels. This makes it suitable for satellite communications, phased-array antennas and future 6G networks integrating space, air and ground infrastructure.

China is building more domestic capability across this value chain as US technology controls increase pressure for semiconductor self-sufficiency.

CETC-linked companies are already supplying advanced components for Chinese spacecraft and communications systems. Recent mass production of millions of GaN RF chips indicates that China is moving some advanced compound semiconductor technology from specialised programmes toward higher-volume deployment.

Indium phosphide could benefit from another part of the satellite market. InP is important for high-speed optical communications and photonic systems, which could become increasingly valuable as satellite networks move larger volumes of data.

Silicon germanium also offers advantages in high-frequency and radiation-sensitive electronics, adding another specialty materials route into the expanding space semiconductor market.

The result is a broader materials opportunity. Satellite growth is no longer only about aluminium structures, titanium components and propulsion materials; semiconductor-grade gallium, indium and germanium are becoming increasingly important.

Orbital Manufacturing Could Open a New Semiconductor Investment Cycle

The US is also considering greater policy support for semiconductor manufacturing in space. Proposed legislation would clarify that semiconductor manufacturing in LEO can qualify for incentives under the CHIPS and Science Act.

The objective reflects growing concern that China could gain an early advantage in orbital manufacturing.

Microgravity manufacturing is attracting interest because some semiconductor materials could potentially be produced with fewer defects and improved uniformity compared with terrestrial processes.

Private companies are accelerating that development. SpaceX, Blue Origin, Google and specialist manufacturers are exploring concepts ranging from orbital data centres to in-space semiconductor production.

The economic model of the space industry is also changing. Commercial investment now represents a much larger share of total space spending than government budgets, increasing the pace at which new technologies can move from development into deployment.

Reusable rockets, lighter satellites and higher-volume manufacturing have reduced the cost of deploying large constellations. Advanced antennas and semiconductor systems originally developed for military applications are also moving into commercial markets.

For metals and materials suppliers, this creates another high-growth demand channel. Aerospace-grade titanium and nickel alloys remain important, but the next phase of the space economy will increasingly depend on advanced semiconductor materials and high-purity minor metals.

The Metalnomist Commentary

The LEO race is becoming a materials race as much as a satellite race. Gallium, indium and germanium could gain strategic value as communications, computing and semiconductor manufacturing move increasingly into orbit.

UCB Power BESS Production Gains Tax Support in Brazil

UCB Power

UCB Power BESS production will receive tax support as Brazil seeks to expand domestic manufacturing of battery energy storage systems. The Brazilian battery producer will benefit from reduced import tariffs on foreign components used in production.

UCB Power BESS production adds another industrial layer to Brazil’s growing energy storage market. The incentives will be administered through the Manaus Free Trade Zone framework, although specific tariff reductions have not been disclosed.

UCB Power BESS production also has implications for critical mineral demand. Lithium-ion storage systems require materials including lithium, nickel, cobalt, manganese, graphite, copper and aluminium across cells, electrical systems and enclosures.

The policy therefore supports more than battery assembly. It could help Brazil gradually build a domestic energy storage ecosystem around renewable power, grids and industrial electricity management.

Tax Incentives Strengthen Domestic Battery Manufacturing

Brazil’s Manaus Free Trade Zone provides tax incentives intended to encourage industrial production in the country’s northern region.

UCB Power will gain lower import costs for foreign components required in BESS manufacturing. This can improve the competitiveness of domestic production while Brazil develops more local supply capability.

The incentives remain subject to standard requirements within the Manaus framework, including environmental and research obligations.

Battery storage manufacturing remains dependent on imported cells, materials and electronic components in many emerging markets. Lower tariffs can therefore reduce the cost disadvantage faced by local manufacturers during the early stages of industry development.

UCB already operates battery factories in Manaus and Extrema, Minas Gerais. The company says its portfolio represents more than 7.8GWh of installed capacity.

That existing manufacturing base gives UCB a stronger position to expand into grid-scale and industrial energy storage as Brazilian electricity demand evolves.

BESS Growth Could Create New Critical Mineral Demand

Battery energy storage is becoming increasingly important as power systems integrate more intermittent renewable generation.

BESS installations can store electricity when supply is abundant and discharge it when demand rises, improving grid flexibility and helping industrial users manage electricity costs.

Lithium-ion technology currently dominates the market, creating demand across a broad range of battery materials.

For Brazil, this creates an opportunity to connect domestic battery manufacturing with its substantial mineral resource base. The country has resources across lithium, nickel, manganese and other materials relevant to energy storage.

However, mineral availability alone will not create an integrated battery industry. Brazil will need refining, active materials production, cell manufacturing and recycling capacity if it wants to capture more of the value chain.

Supporting BESS assembly is therefore an early step toward a broader industrial ecosystem rather than the endpoint.

The Metalnomist Commentary

Brazil has the mineral resources and renewable power base to build a larger battery industry, but the missing link remains downstream processing and cell production. UCB’s expansion can help create domestic demand that makes those investments more commercially attractive.

Utah Direct Lithium Extraction Project Advances With Posco-Anson Partnership

Anson Resources

Utah direct lithium extraction development is moving forward after Posco and Anson Resources agreed to build a demonstration plant at the Green River Lithium project in the Paradox Basin.

Utah direct lithium extraction will use Anson’s brine resources, while Posco will lead the design, construction and operation of the demonstration facility. Posco will also pay Anson a $5.2mn facilitation fee under the agreement.

Utah direct lithium extraction is strategically important because the project targets domestic battery-grade lithium production without relying on conventional evaporation ponds. Operations at the demonstration facility are scheduled to begin in 2027, with completion expected in 2028.

The wider Green River project is designed to produce 10,000 t/yr of lithium carbonate and has already secured major permits, financing interest and an anchor customer.

DLE Demonstration Will Test Commercial Processing Route

The demonstration plant will determine whether Posco’s DLE technology can recover lithium from Green River brines efficiently and consistently enough for commercial-scale production.

Direct lithium extraction is attracting growing interest because it can potentially reduce land use and shorten processing times compared with traditional brine evaporation.

However, commercial performance depends heavily on brine chemistry, recovery rates, reagent consumption and water management. Demonstration-scale operation is therefore a critical step before committing to full production.

Posco’s involvement adds technical and industrial expertise to the project. The Korean group has been expanding across battery materials and lithium supply chains, giving the Green River project a stronger downstream connection.

If the demonstration performs as expected, Anson would have a clearer route toward financing and construction of the 10,000 t/yr commercial operation.

Financing and Offtake Strengthen Green River Economics

Green River has already secured several important elements needed for project development.

The US Export-Import Bank has issued a $330mn letter of interest, providing a potential source of debt financing for the project.

Anson also has a binding offtake agreement with LG Energy Solution covering 40% of expected production. That provides long-term demand visibility and directly connects future Utah lithium output with battery manufacturing.

Estimated capital expenditure stands at $495mn, while projected operating costs are $4.37/kg of lithium carbonate equivalent.

Those economics could make Green River competitive if the DLE process reaches targeted recoveries and operating performance.

The combination of Posco technology, US financing support and LG Energy Solution offtake also illustrates how lithium projects are increasingly being developed through integrated partnerships rather than mining companies acting alone.

The Metalnomist Commentary

Green River is becoming a test of whether DLE can move from promising technology to bankable US lithium production. Posco’s involvement reduces technical risk, while Ex-Im financing and LG Energy Solution offtake strengthen the project’s commercial foundation.

Norsk Titanium RPD Technology Targets US Submarine Applications

Norsk Titanium

Norsk Titanium RPD technology is moving deeper into US defense applications after the company secured a $4.2mn contract to develop rapid plasma deposition for maritime and submarine use.

Norsk Titanium RPD technology will be developed over an 18-month period under the Defense Industrial Base Expansion, Development, and Growth Enterprise initiative. The work will focus on qualifying additive-manufactured products for highly critical naval applications.

Norsk Titanium RPD technology is already established around titanium alloys, but the new programme will also expand the process into nickel-based alloys. That broadens the potential market from corrosion-resistant structural components into higher-temperature and more demanding applications.

The programme is strategically important because submarine supply chains require highly qualified materials, long service lives and strict control over metallurgy and manufacturing consistency.

Titanium Additive Manufacturing Fits Maritime Corrosion Requirements

Titanium is especially valuable in marine environments because of its strong corrosion resistance in seawater.

Commercially pure titanium and alloys such as Grade 5 and Grade 7 can provide long-term durability where conventional steels would require greater corrosion protection or maintenance.

This makes titanium attractive for submarine and maritime components exposed to saltwater, pressure and difficult operating conditions.

Additive manufacturing can add another advantage. Near-net-shape production can reduce the amount of expensive titanium that must be machined away from forged or wrought stock.

That can improve material utilisation and shorten lead times for complex components, particularly where conventional manufacturing requires large forgings or extensive machining.

For defense programmes, reducing dependence on long-lead forgings can be strategically valuable. Qualified additive processes could provide an alternative route for components where supply capacity is constrained.

However, qualification remains the critical barrier. Submarine components operate in safety-critical environments, so mechanical properties, fatigue behaviour, defect control and repeatability must be demonstrated before widespread adoption.

Nickel Alloys Could Expand RPD Beyond Structural Titanium

The move into nickel-based alloys could significantly broaden Norsk Titanium's addressable market.

Nickel superalloys are widely used where components must retain strength, corrosion resistance and thermal stability under demanding conditions.

For naval applications, this could create opportunities in propulsion, high-temperature systems and specialised mechanical components alongside titanium structures.

The combination of titanium and nickel alloy capability would also strengthen Norsk Titanium's position as a broader defense manufacturing supplier rather than a single-material additive producer.

The US defense industrial base is increasingly focused on manufacturing resilience, particularly for components dependent on limited forging, casting or machining capacity.

RPD technology could support that objective if it can reduce lead times while meeting military qualification standards.

The longer-term significance therefore lies in process substitution. Norsk is not simply selling additive manufacturing equipment; it is trying to qualify a new production route for materials and components traditionally supplied through conventional metallurgical processes.

The Metalnomist Commentary

Norsk Titanium's submarine programme shows that additive manufacturing is moving into increasingly critical defense applications. If RPD qualifies successfully in both titanium and nickel alloys, the technology could reduce dependence on long-lead forgings and expand flexibility across the naval supply chain.

Brazil Critical Mineral Processing Lags Despite Vast Resource Base

Brazil, critical mineral

Brazil critical mineral processing remains far behind the country's resource potential despite growing political pressure to capture more value domestically. President Luiz Inacio Lula da Silva has increasingly tied future critical minerals partnerships to local processing and refining.

Brazil critical mineral processing has become more important as Brasilia seeks to avoid remaining only a raw material exporter. The lower house approved a bill in May that would provide incentives to miners that process and refine minerals inside the country.

Brazil critical mineral processing still faces major structural barriers. Industry participants say Brazil lacks sufficient mine output, processing technology, skilled workers and regulatory capacity to support large-scale downstream development.

The gap is striking. Brazil holds a significant share of global critical mineral reserves, yet contributes less than 1% of total production under government estimates.

Processing Ambitions Face Technology and Skills Gap

Brazil's first challenge is increasing upstream production before large-scale processing can become commercially viable. Significant reserves alone do not create sufficient feedstock for refineries and advanced materials plants.

The government has acknowledged that bureaucracy and limited geological information continue to slow mine development. Faster permitting and better resource data would improve access to financing and increase the number of projects reaching production.

Technology represents another major bottleneck. Different critical minerals require distinct extraction, separation and refining processes, preventing Brazil from applying a single processing model across the sector.

Rare earths present one of the most difficult challenges. Brazil has mining expertise but lacks enough engineers and technicians with experience in industrial rare earth separation and permanent magnet production.

This creates a dependency on international partnerships. Technology transfer, research cooperation and specialist investment will be necessary if Brazil wants to move from concentrate production into separated oxides, metals, alloys and magnets.

The opportunity is significant because downstream processing captures substantially more value than raw mineral exports. It can also support automotive, defence, electronics and clean energy manufacturing inside Brazil.

Regulation and Permitting Could Delay Industrial Scale-Up

Brazil's critical minerals bill could provide clearer incentives for domestic processing, but its passage through the senate remains uncertain.

Industry groups want the legislation completed before elections reshape congress. Delays could force policymakers to restart negotiations with a different group of lawmakers.

The country's mining regulator also faces severe staffing constraints. The National Mining Agency remains significantly understaffed and has thousands of economic plans awaiting review.

These bottlenecks can slow both exploration and mine development, making it harder to create the feedstock base required for downstream processing.

Brazil therefore faces a sequencing problem. The country wants processing investment, but processors need reliable mine supply, regulatory certainty, infrastructure and qualified workers before committing capital.

If those conditions improve, Brazil could use its resource base to build a much stronger industrial position in rare earths and other critical minerals. Without them, the country risks remaining primarily an exporter of unprocessed resources.

The Metalnomist Commentary

Brazil's critical minerals opportunity is enormous, but reserves alone do not create industrial power. The decisive step is building the technology, permitting capacity and skilled workforce needed to convert geology into refined materials and advanced products.

Colorado Battery Recycling Law Sets Mandatory Lithium Recovery Targets

Colorado Battery Recycling

Colorado battery recycling law introduces mandatory recovery targets for lithium, nickel and cobalt from electric and hybrid vehicle batteries. The measure creates a more structured framework for recovering critical minerals from end-of-life batteries.

Colorado battery recycling law requires recyclers to recover 50% of lithium from spent batteries by 2031 and 80% by 2035. Nickel and cobalt recovery must reach 90% by 2031.

Colorado battery recycling law will also prohibit landfilling of EV batteries from July 2029. This should push more used packs toward reuse, dismantling and materials recovery.

The legislation strengthens the commercial case for domestic battery recycling by creating clearer collection obligations and long-term recovery requirements.

Mandatory Recovery Targets Support Secondary Battery Materials

The Battery Stewardship Act requires battery stewardship organizations to submit plans covering collection, transportation, processing and recycling.

The lithium target is particularly important because recovering lithium economically has historically been more challenging than recovering nickel and cobalt.

A 50% recovery requirement by 2031 gives recyclers time to improve process efficiency before the threshold rises to 80% in 2035.

The 90% recovery requirement for nickel and cobalt sets an even higher standard. Both metals remain valuable inputs for several lithium-ion battery chemistries.

Recovering these materials can reduce dependence on newly mined supply and create more domestic secondary feedstock for battery manufacturers.

The landfill ban reinforces that objective by keeping valuable battery materials inside the industrial supply chain.

Producer Fees Could Improve Battery Collection and Recycling Economics

Battery providers will fund part of the system through fees linked to their share of battery vehicles registered in Colorado.

An initial programme fee will support implementation. Annual payments beginning by July 2030 will cover administration, enforcement and regulatory costs.

This shifts more responsibility for end-of-life batteries toward companies placing battery vehicles into the market.

The framework could also improve feedstock certainty for recyclers. Reliable access to spent batteries remains one of the biggest challenges facing the emerging US battpery recycling industry.

Over time, the legislation may encourage better pack design for dismantling, reuse and materials recovery.

If similar policies spread to other states, US battery recycling could develop around mandatory recovery standards rather than voluntary collection alone.

The Metalnomist Commentary

Colorado is turning battery recycling into a regulated critical minerals supply chain. The most important benefit may be feedstock certainty, because recyclers need predictable battery volumes as much as better recovery technology.

Brazil Semiconductor Production Gains BNDES Funding as Industrial Strategy Expands

Zilia Technologies

Brazil semiconductor production will receive new government-backed financing after development bank BNDES approved a R143.3mn loan for Zilia Technologies. The funding will support research, production expansion and modernization of the company's manufacturing facilities.

Brazil semiconductor production is becoming part of a broader industrial strategy aimed at reducing dependence on imported electronic components. Zilia will use the financing to develop semiconductor products for smartphones, computers, vehicles, security equipment and other technology markets.

Brazil semiconductor production also increasingly connects with the country's critical minerals strategy. BNDES is preparing major investment in lithium, cobalt, nickel, rare earths and other strategic materials as Brazil seeks to capture more value from its mineral resources.

The investment strengthens Brazil's ambition to move beyond raw material exports and build more domestic advanced manufacturing capacity.

BNDES Funding Targets Domestic Semiconductor Capability

Zilia will use part of the financing to modernize its facilities in Atibaia, Sao Paulo state. The investment is intended to expand research capabilities and improve semiconductor production.

Brazil currently depends heavily on imported technology components, making domestic manufacturing capacity strategically important for electronics, automotive and industrial sectors.

Semiconductors have become increasingly important to vehicle production as electrification, connectivity and advanced driver systems increase chip content per vehicle.

Consumer electronics and security systems provide additional markets for domestic production.

BNDES sees the investment as a way to strengthen industrial resilience while reducing exposure to overseas component shortages.

The financing also builds on Brazil's wider industrial policy. The country's new industry programme launched in 2024 included plans for annual investment to strengthen domestic semiconductor capabilities.

Critical Minerals Could Support a Broader Technology Value Chain

Brazil's semiconductor ambitions sit alongside a much larger critical minerals investment strategy.

BNDES has indicated plans to deploy R50bn into projects linked to strategic minerals including lithium, cobalt, nickel and rare earth elements.

These materials support wider electronics, battery, magnet and advanced manufacturing supply chains. Brazil's large resource base gives the country an opportunity to connect mineral extraction with higher-value industrial processing.

Brazil holds significant reserves of critical minerals, but much of their economic value can be lost if materials are exported before refining, conversion or advanced manufacturing.

The strategic opportunity is therefore downstream integration. Domestic processing, specialty materials and electronics production could allow Brazil to capture more value from resources already present inside the country.

Semiconductor manufacturing itself also depends on highly specialised materials, chemicals, gases and equipment. Building a competitive domestic industry will therefore require more than mineral availability alone.

Brazil will need technology, skilled labour, infrastructure and long-term private investment alongside government financing.

The Metalnomist Commentary

Brazil's opportunity lies in linking mineral wealth with higher-value technology manufacturing rather than treating the two strategies separately. BNDES funding can provide the bridge, but competitiveness will depend on building the processing, materials and technical ecosystem between mines and semiconductor production.

India Aluminium Import Duties Extended to Shield Domestic Producers

India anti-dumping duties

India aluminium import duties will remain in place on selected foil and wire rod products as the government extends trade remedies against imports from several Asian suppliers.

India aluminium import duties include anti-dumping measures on aluminium foil from China, Malaysia, Thailand and Indonesia through 15 December. The government is reviewing whether removing the duties could lead to renewed dumping and harm domestic manufacturers.

India aluminium import duties also cover countervailing measures on aluminium wire rod from Malaysia. That levy will remain in place until 23 March 2027.

The extensions give Indian aluminium processors greater protection from lower-priced imports while the government continues to prioritise domestic manufacturing and value-added production.

Foil Producers Gain More Protection From Asian Imports

The aluminium foil anti-dumping duty applies to imports from China, Malaysia, Thailand and Indonesia. The measure was originally introduced to protect Indian producers from shipments priced below fair market levels.

Extending the duty gives domestic foil manufacturers more certainty while the government evaluates longer-term market conditions.

This matters because aluminium foil is a higher-value downstream product used across packaging, batteries, pharmaceuticals and industrial applications.

Indian producers face strong competition from established Asian manufacturers with large-scale production and export networks. Lower import prices can quickly pressure margins when domestic demand weakens.

Maintaining anti-dumping protection can therefore support utilisation rates and investment in local converting capacity.

However, higher import barriers can also increase costs for downstream users if domestic supply is insufficient or priced significantly above international levels.

The policy balance will depend on whether Indian manufacturers can expand capacity while remaining competitive on quality and price.

Wire Rod Measures Support Domestic Aluminium Processing

India has separately extended countervailing duties on Malaysian aluminium wire rod until March 2027.

The measure applies to aluminium wire and rod in coil form with diameters of 9-13mm. Countervailing duties are designed to offset advantages created by foreign government subsidies.

India imported 100,571t of aluminium wire rod in 2025 and another 21,273t during the first quarter of 2026, showing that overseas supply remains relevant to the domestic market.

Wire rod is an important intermediate product for electrical conductors, cables and other fabricated aluminium applications.

Protecting domestic production could therefore support a broader aluminium value chain extending from primary metal through wire, cable and electrical infrastructure.

The extensions also fit India's wider industrial policy. New Delhi increasingly uses tariffs, trade remedies and manufacturing incentives to encourage local processing rather than dependence on imported finished or semi-finished products.

For aluminium producers, this creates a more protected domestic market. But long-term competitiveness will still depend on power costs, scale, technology and downstream demand.

The Metalnomist Commentary

India is using trade remedies to protect higher-value aluminium processing rather than only primary metal production. The real test will be whether this protection translates into stronger domestic capacity without raising costs too far for downstream manufacturers.

Tianhao Magnesium Alloy Plant Targets NEV and Aerospace Lightweighting Demand

Huizhou Tianhao New Material Technology

Tianhao magnesium alloy plant development has started in Huizhou, Guangdong province, as Chinese manufacturers expand capacity for lightweight materials used in new energy vehicles, electronics and aerospace.

Tianhao magnesium alloy plant is designed to produce 20mn units/yr of magnesium alloy profiles. The company has not disclosed a start-up timeline, but construction began on 4 June.

Tianhao magnesium alloy plant development reflects rising demand for lightweight structural materials across NEVs, consumer electronics, low-altitude aviation and aerospace. Magnesium's low density gives it an advantage where reducing component weight can improve energy efficiency and vehicle performance.

China already dominates global magnesium production and processing, giving domestic manufacturers strong access to metal feedstock and downstream fabrication capabilities.

Lightweighting Drives Magnesium Alloy Demand

Magnesium alloys are increasingly used where manufacturers need lower weight without abandoning metallic structural materials. This is especially relevant to electric vehicles, where reducing vehicle mass can improve driving range and offset battery weight.

Consumer electronics provide another important demand segment. Magnesium alloys can be used in lightweight housings and structural components that require stiffness and dimensional stability.

The low-altitude economy could become a larger growth market. Drones, electric vertical take-off aircraft and other lightweight aviation platforms need materials that can reduce mass while maintaining adequate structural performance.

Aerospace applications add further demand potential, although qualification requirements remain much stricter than in consumer or automotive markets.

China produced 428,400t of magnesium alloy in 2025, up 8% from the previous year. Stronger lightweighting demand and pressure to reduce carbon emissions supported the increase.

The Tianhao project therefore enters a market where both production and downstream applications are expanding.

China Strengthens Its Magnesium Processing Advantage

Global magnesium metal consumption reached around 1.2mn t in 2025. Magnesium alloy production represented the largest end-use segment at roughly 650,000t.

Other major applications included steel desulphurisation, aluminium alloying and metal reduction. However, magnesium alloy demand is expected to grow fastest as transportation and electronics markets seek lighter materials.

Global magnesium alloy consumption could reach 1.39mn t by 2028 if current growth expectations materialise. NEVs, consumer electronics and low-altitude aviation are expected to provide much of that increase.

China is well positioned to capture this growth because it controls a large share of global magnesium metal production and already has extensive alloying and fabrication capacity.

That advantage could deepen as manufacturers move further downstream into profiles, castings and finished components rather than selling primary magnesium alone.

For international buyers, this creates a familiar critical materials challenge. Strong Chinese integration can deliver low costs and scale, but it also increases geographic concentration across the magnesium supply chain.

The Metalnomist Commentary

Tianhao's project shows that magnesium is moving further into high-growth lightweighting applications. China's advantage lies not only in producing magnesium metal, but increasingly in converting it into higher-value components for EVs, electronics and aerospace.

Wyoming Rare Earth Plant Targets NdPr Separation Start in Summer 2026

Rare Element Resources

Wyoming rare earth plant development is advancing as Rare Element Resources prepares to begin full operations at its demonstration facility in late summer 2026. The plant will produce separated neodymium-praseodymium oxide and support the engineering of a larger commercial separation facility.

Wyoming rare earth plant development is strategically important because the US still lacks sufficient domestic capacity to separate rare earth feedstock into magnet-ready materials. NdPr oxide is a core input for permanent magnets used in electric motors, defence systems, robotics and advanced industrial equipment.

Wyoming rare earth plant operations are expected to continue for up to 12 months. RER will use the demonstration campaign to generate technical data for the design and construction of a future full-scale processing facility.

The company fully owns the Bear Lodge rare earth project in Wyoming and plans to locate its processing operations nearby in Upton.

Demonstration Plant Targets a Critical US Processing Gap

The demonstration facility is designed to prove RER's separation technology before the company moves toward commercial-scale production. The company has not disclosed planned output volumes for the demonstration plant.

Process performance will therefore matter more than headline tonnage. Recovery rates, product purity, operating reliability and scale-up data will determine whether Bear Lodge can progress successfully toward commercial development.

This distinction is important because rare earth mining alone does not create supply security. Concentrates must be processed and separated into individual oxides before they can enter metal, alloy and magnet production.

Neodymium and praseodymium are particularly important because they are the primary light rare earths used in high-performance NdFeB permanent magnets.

A successful demonstration campaign could therefore move Bear Lodge closer to becoming a domestic source of separated NdPr oxide and strengthen the upstream foundation of the US permanent magnet supply chain.

Fast-41 Status Supports Bear Lodge Development

Bear Lodge was designated as a covered project under the federal Fast-41 permitting programme in March 2026. The designation is intended to improve coordination across federal agencies and provide greater visibility around permitting timelines.

RER expects to complete federal and state permitting and licensing requirements by early 2028.

The company also strengthened its financing position in March by raising $30.5mn through an oversubscribed rights offering. The proceeds will support demonstration plant operations and permitting work for Bear Lodge.

That funding provides RER with additional capital to validate its processing route before committing to a much larger commercial investment.

The next challenge will be converting demonstration-scale success into a bankable project. Full-scale rare earth separation requires substantial capital, reliable feedstock, technical consistency and downstream customer qualification.

If RER achieves those milestones, Bear Lodge could become an important US source of NdPr outside the China-dominated rare earth processing system.

The Metalnomist Commentary

Bear Lodge's strategic value lies in proving separation capability, not simply adding another rare earth resource. If RER validates its process and completes permitting on schedule, Wyoming could become a meaningful building block in the US magnet supply chain.

CETC GaN Chips Push GaN-on-Silicon RF Technology Into Commercial Scale

CETC

CETC GaN chips have reached a major commercial milestone after China Electronics Technology Group delivered more than 5mn silicon-based gallium nitride radio-frequency chips for smart terminals. The state-owned manufacturer described the product as the first commercially mass-produced GaN-on-silicon RF chip for this application.

CETC GaN chips are strategically important because GaN combines strong high-frequency and high-power performance with the cost advantages of silicon substrates. This could accelerate adoption in next-generation communications equipment where performance and scale are both critical.

CETC GaN chips are expected to support integrated space-air-ground communications networks used across 6G, commercial aerospace, low-altitude aviation and emergency communications.

The development also strengthens the long-term demand outlook for gallium. Wider GaN deployment will require more high-purity gallium and more advanced downstream processing capacity.

6G and Aerospace Expand the Market for GaN RF Chips

RF power amplifiers are critical components in modern communications systems because they influence transmission range, signal quality and data throughput.

GaN technology is well suited to these applications because it can operate efficiently at higher frequencies and power levels than conventional semiconductor materials.

That makes GaN increasingly relevant to 6G networks, satellite communications, aerospace systems, radar and low-altitude aviation platforms.

China’s rapid expansion in commercial aerospace, information communications and the low-altitude economy is creating a larger domestic market for high-performance RF chips.

Mass production is therefore as important as technical capability. Delivering more than 5mn units shows that GaN-on-silicon is moving from specialised applications toward broader commercial deployment.

This shift could lower unit costs and make GaN-based systems more practical for large-scale communications infrastructure.

Gallium Moves Deeper Into Strategic Semiconductor Supply Chains

The expansion of GaN production has direct implications for gallium demand. Semiconductor-grade GaN requires highly refined gallium with strict purity and processing standards.

As chip output rises, demand will increasingly shift from basic gallium metal toward higher-value materials suitable for epitaxy, wafers and semiconductor fabrication.

China already dominates global gallium supply and has included the metal in its dual-use export control regime since 2023.

That gives domestic GaN expansion wider strategic importance. More gallium may be consumed inside China as semiconductor demand grows, increasing pressure on overseas buyers to diversify supply.

The development also raises the value of downstream refining and processing. Future competition will depend not only on access to gallium, but on the ability to convert it into qualified semiconductor materials.

For global markets, this means gallium is becoming increasingly tied to communications, aerospace and defence technology rather than remaining a small-volume specialty metal.

The Metalnomist Commentary

CETC’s mass delivery shows that GaN is moving decisively from niche applications into commercial-scale communications. The strategic bottleneck is likely to shift upstream toward high-purity gallium and qualified semiconductor materials as 6G and aerospace demand expands.
