The West Chester Division OEM business segment is an industry leader in precision stamping of aerospace components with increased capabilities in milling, turning, drilling and advanced grinding.  Located on the same campus as our Maintenance, Overhaul and Repair (MRO) business, the West Chester OEM operation maintains a unique position, leveraging synergies between the two business segments, emulating the comprehensive Barnes Aerospace
‘Go-to-Market’ strategy.

Barnes Aerospace’s OEM operations produce precision machined and fabricated components and assemblies for turbine engines, nacelles, airframes and industrial gas turbines throughout the world.  We are highly regarded for our complex components and assemblies made of exotic and high temperature metals, including titanium, iconel, hastelloy, stainless steel and nickel alloy materials.

Each location at Barnes Aerospace offers our customers total program management support throughout the entire life cycle of the products.  We partner with our customers to understand their requirements and with concurrent engineering solutions, we are able to deliver superior service with leading turn-around times – all for competitive prices.
