Mission-Critical Metal Components For The Defense Industry

MetalTek helps the defense industry push the limits of performance through critical metal components that ensure the safety of the military and those they protect.  Our broad selection of alloys promotes longer life in environments that demand high tensile and yield strength along with resistance to corrosion and wear.  Carondelet is certified to produce HY-80 steel to NAVSEA Technical Publication T9074 and is one of few manufacturers to offer HY-80 using sand casting.

MetalTek’s manufacturing expertise includes centrifugal casting, investment casting, and sand casting.  Our state-of-the-art facilities provide a range of components for defense applications such as submarine and surface ship propulsion, weapons systems, fluid control, and structural support.  MetalTek is a Level 1 supplier accredited by ISO, Nadcap, and a range of other certification programs to ensure compliance with the strictest quality demands.

You cannot be in defense halfway.  MetalTek has the technical expertise and experience to help defense customers and the military do their jobs and keep us safe.
