Copper beryllium, also known as beryllium bronze, is a copper alloy with 0.5—3% beryllium. Copper beryllium is the hardest and strongest of any copper alloy (UTS up to 1,400 MPa), in the fully heat treated and cold worked condition. It combines high strength with non-magnetic and non-sparking qualities and it is similar in mechanical ...Web

ABSTRACT. An anomalous phenomenon has been newly found in a copper-1.90mass% beryllium alloy containing 0.28mass% cobalt through an investigation of the aging behavior of the alloy under external stress. A plate of the Cu-Be alloy was elastically bent by an external load and aged at 633K under the stressed condition.Web
