CuBe2

Copper Alloys

EN CW101C - UNS C17200

CuBe2 is a copper alloy with very high mechanical strength that can be precipitation-hardened after heat treatment. It combines excellent elasticity with very good fatigue and wear resistance, while maintaining adequate thermal and electrical conductivity for an alloy in this class. It is one of the highest-performing copper alloys in terms of mechanical strength.
