Beryllium copper factory, more than 10 years manufacture experience, attained ISO9001, work on OEM and ODM projects..
1. Introduction of the CuBe2 beryllium copper strip
Cube2 /C17200 Beryllium Copper is the most commonly utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. CuBe2/C17200 alloy contains appr. 2% of beryllium and achieves its ultimate tensile strength can exceed 200 ksi, while the hardness approaches Rockwell C45. Meanwhile, the electrical conductivity is a minimum of 22% IACS in the fully aged condition.
CuBe2/C17200 also exhibits exceptional resistance to stress relaxation at elevated Temperatures
