What are Different Types of Alloys Used in Defence Industry


Solutions that power and protect
Military readiness depends on systems that can respond anywhere and any time with speed, precision and resilience. Our specialty materials play a key role in supporting this effort — in jet engines; structures for land vehicles; systems for ships; and sophisticated armor that protects systems and people when they’re in harm’s way. Through an extensive, integrated, U.S.-based supply chain, we produce a wide range of military-grade titanium, specialty steels, and other materials and components for defense contractors and other customers. We make these materials available in a complete range of forms and processes, and have the resources to fabricate components as well. Our dedicated defense team supports customers with engineering, materials knowledge and technical support.
