Copper alloy with beryllium as the main alloy element - Beryllium copper for short. In addition to containing beryllium, beryllium bronze generally contains nickel or cobalt, as well as elements such as S, Al, Ti, Mg and Ag. beryllium bronze is the best advanced elasticity materials among copper alloys. It has a series of excellent physical, chemical and mechanical properties, such as high strength, elasticity, hardness, fatigue strength, small elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, impact without spark, and is one of the important materials in industry. There are processed beryllium bronze and foundry beryllium bronze. foundry beryllium bronze contains high beryllium or diamond. In order to improve the flow ability of alloy, less ft silicon is often added. Adding silver can improve the conductivity. The beryllium content of processed beryllium bronze is controlled below 2%. Chinese beryllium copper added to 0. 3% nickel and 0.3% cobalt for some beryllium bronze. The role of nickel and cobalt in alloy is to inhibit premature over aging of alloy. beryllium bronze is a heat treatment strengthened alloy. beryllium bronze is mainly used as various advanced elasticity components, especially those requiring good conductivity, corrosion resistance, wear resistance, cold resistance, and non-magnetic properties, which are widely used as membrane, diaphragm, bellows, micro switches, etc. foundry and bronze are used for explosion-proof tools, various moulds, cams, bearings, bearing shells, bearing sleeves, gears and various electrodes. The oxide and dust of beryllium are harmful to the body, and attention should be paid to protection during production and use.
