Mission-critical defense solutions for over 70 years

MetalTek helps the defense industry push the limits of performance through high-quality components that ensure the safety of the military and those they protect.

MetalTek’s  9,000-pound centrifugal hub castings transfer 50,000 horsepower per propeller shaft and drive 100% of Naval frigates and destroyers.  Metal Matrix Composite (MMC) material from MetalTek extended the life of friction drum linings in winches transferring supplies from replenishment vessels to other Navy Ships by virtually eliminating corrosion and drum wear.

Centrifugally-cast shaft sleeves from MetalTek save millions of dollars in maintenance per year on Navy ships and submarines through enhanced performance and even wear.  High-strength MetalTek components help the Air Force's Tunner Loader move 60,000-pound pallets onto military cargo planes while making the Tunner light enough to transport on a C-130 aircraft.

You can't be in the defense industry halfway.  MetalTek’s components are provided from multiple Nadcap-certified facilities that feature a range of metal casting processes and a broad selection of alloys.  We have systems to ensure compliance with International Traffic In Arms Regulations (ITAR) and Export Administration Regulations (EAR).  MetalTek has the technical expertise and depth of experience to help our defense customers and the military do their jobs and keep us safe.
