  • Description

This is a precipitation hardening copper alloys. It has high mechanical and electrical properties. In the artificial aged temper, the alloy exhibits high strength and hardness, good wear resistance and fatigue resistance, high corrosion resistance, high electrical and thermal conductivity. This alloy has excellent hot forming. Cold working before precipitation hardening can further improve strength and hardness.
