Beryllium Copper C17000 (UNS C17000) generally consists of 1.6–1.85% beryllium, with the remainder being copper and a few trace elements like cobalt. This alloy undergoes precipitation hardening to achieve impressive strength (with tensile strength reaching up to 1380 MPa) while still maintaining good electrical conductivity (up to 22% IACS). It also boasts excellent fatigue strength, wear resistance, and non-magnetic characteristics. C17000 holds its mechanical integrity even in high-temperature and high-stress situations, making it perfect for precision components that face heavy cyclic loading and electrical performance challenges in tough environments.
