Characteristics and main uses
This alloy achieves the highest mechanical strength or hardness after hardening of any copper alloy on the market, and is commonly used. It has excellent bending properties in the “solution set”: A, “solution set and slightly work-hardened”: 1⁄4 H and 1⁄2 H states. In the hardened states after shaping, it can achieve mechanical strengths in excess of 1400N/mm2. CuBe2 alloy features high fatigue strength, excellent thermal relaxation resistance and a unique combination of mechanical strength and conductivity.
