Mechanical Properties
Characteristics
CAMK17200 is the most commonly specified copper beryllium.
In its age hardened condition, it attains the highest strength and hardness of any commercial copper base alloy. The ultimate tensile strength can exceed 1360Mpa(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). It also exhibits exceptional resistance to stress relaxation at elevated temperatures.
