C****0 Beryllium Copper

Cube**-C****0 (CDA **2) Beryllium Copper is the most commonly utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. C****0 alloy contains appr. 2% of beryllium and achieves its ultimate tensile strength can exceed **0 ksi, while the hardness approaches Rockwell C*5. Meanwhile, the electrical conductivity is a minimum of *2% IACS in the fully aged condition.C****0 also exhibits exceptional resistance to stress relaxation at elevated temperatures.
