 | Round Beryllium Copper Rod - Alloy 25
Alloy 25 (UNS C17200) is the most commonly specified beryllium copper and is available in several wrought forms. In its age-hardened condition, Alloy 25 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% IACS (International Annealed Copper Standard). Alloy 25 also exhibits exceptional resistance to stress relaxation at elevated temperatures.
