Copper/Beryllium Alloy Wire (Cu98/Be 2)

Goodfellow’s copper/beryllium alloy wire (Cu98/Be2) combines the high electrical and thermal conductivity of copper with the strength and stiffness of beryllium. The addition of just 2% beryllium to copper increases the alloy's yield strength and elastic modulus significantly compared to pure copper. This copper-beryllium wire maintains its properties at both cryogenic and elevated temperatures. Common applications include springs, electrical contacts, and precision instrument parts requiring high strength, resilience, and conductivity. Overall, Goodfellow’s copper/beryllium alloy wire offers an optimal balance of conductivity and mechanical properties within their wide selection of wire products.
