Overview
C81540 is a copper alloy with chromium added for strength and wear resistance. It maintains electrical conductivity and thermal stability at high temperatures. This makes it suitable for demanding applications. C81540 resists oxidation and softening but may corrode in some environments.
Typical Uses
Applications where more strength and hardness than other copper alloys is needed.
