Description

Copper Alloy C17200 is the most commonly specified copper beryllium alloy. In its age hardened condition, it attains the highest strength and hardness of any commercial copper base alloy. The ultimate tensile strength can exceed 200 ksi, while the hardness approaches Rockwell C45. Also in the fully aged condition, the electrical conductivity is a minimum of 22 percent IACS. C17200 also exhibits exceptional resistance to stress relaxation at elevated temperatures.
