CuCoNiBe

Copper Alloys

EN CW103C - UNS C82200

CuCoNiBe is a copper alloy with very high mechanical strength that combines excellent thermal conductivity with good electrical conductivity. Thanks to the structural hardening achieved through heat treatment, it exhibits very good resistance to fatigue, wear, and high temperatures. It is particularly used in technical applications subject to high mechanical and thermal stresses.
