Acquires ATI East Hartford Machining Operations

Barnes Aerospace

Barnes Aerospace acquires ATI East Hartford machining operations to deepen its engine-parts footprint. The deal strengthens access to titanium and nickel alloy machining and extends Barnes’ reach into defense programs. Barnes Aerospace acquires ATI East Hartford machining operations as part of a focused capacity build.

Deal expands engine machining capacity

Barnes Aerospace acquires ATI East Hartford machining operations to boost rotary disc capability. The 110,000ft² site machines discs for jet engines in titanium and nickel alloys. Proximity to Barnes East Granby plant enables faster turnarounds and shared quality systems. As a result, customers gain reduced logistics risk and tighter delivery control. ATI deemed the asset non-core within its broader capacity strategy.

Implications for titanium and nickel alloy supply chains

The acquisition tightens integration across titanium and nickel alloy value chains. Barnes can balance workloads between East Hartford and East Granby for military and commercial engines. Meanwhile, rotorcraft and defense programs benefit from localized machining depth. The move also supports OEMs managing schedule risk amid ongoing component bottlenecks. Suppliers should expect steadier demand for forgings and bar in premium grades.

Barnes positions for aftermarket and OEM growth with added critical-process capacity. Disc machining sits on the critical path for engine build rates and MRO. Therefore, incremental capacity can ease turnaround times and stabilize delivery cadence. Engine primes seeking reliable rotor hardware will likely welcome the added redundancy. The transaction aligns with industry efforts to derisk single-point suppliers.

The Metalnomist Commentary

This is a classic “closer to the engine” move that monetizes bottleneck processes. Expect firmer pull for titanium and nickel superalloy feedstocks tied to discs and forgings. If build rates improve into 2026, Barnes’ Connecticut footprint should capture higher-margin work.
