Diameter 20mm Length 1000mm ASTM B194 C17200 Copper Beryllium Rod
 

Common Name: C17200, alloy25, CuBe2, QBe2.0, DIN 2.1247

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. 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.C17200 also exhibits exceptional resistance to stress relaxation at elevated temperatures.
