Allied to aluminum and totally committed to titanium, GKN Aerospace Chem-tronics fabricates components (such as doors, ducts, enclosures, exhaust nozzles, keels, and bulkheads) for commercial and military aircraft, as well as spacecraft. The company, a subsidiary of auto parts maker GKN, specializes in lightweight chemically milled titanium and aluminum alloy parts for engines, airframe structures, and launch vehicles. GKN Aerospace Chem-tronics has made components for Aerojet, Allison, Boeing, General Electric, Lockheed Martin, Pratt & Whitney, and other aerospace companies. Additional products include complex welds, cases, modules, pressure vessels, and rings. The company was founded in 1953.


GKN Aerospace Chem-tronics is part of GKN Aerospace Services group, which has engineering and manufacturing operations in Australia, Germany, Mexico, the UK, and the US. It has two service groups: Aerospace Components and Aviation Repair.

Aerospace Components specializes in its branded lightweight Unistructure and Unisandwich chemically-milled alloy parts for engines, airframe structures, and launch vehicles. Every new military fighter and bomber aircraft jet engine built in America since 1976 has utilized Unistructure bypass ducts.

Aviation Repair has the capability of handling repairs for major manufacturers including International Aero Engines, Honeywell, and General Electric. Chem-tronics repairs fan and compressor blades, fan disks, and cases for jet engines in service around the world. It applies protective carbide coatings to improve the lifespan of blades and increase their durability.


In order to enhance its manufacturing capabilities, in 2012 Chem-tronics established a new 80,000 sq. ft. composite manufacturing facility. The location works in tandem with the company's Alabama facility, which is growing.
