CuCo2Be

Copper Alloys

EN CW104C - UNS C17500

CuCo2Be has machinability similar to that of pure copper, while offering significantly improved mechanical properties thanks to the addition of cobalt and beryllium. This alloy is characterized by very good corrosion resistance and excellent mechanical properties. Its high performance makes it a widely used material in many demanding industrial sectors.
