Explanation

Copper alloy with beryllium as the main alloy element is called beryllium copper for short. In addition to beryllium, beryllium copper generally contains nickel or cobalt, as well as elements such as Si, Al, Ti, Mg, and Ag. Beryllium copper 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, etc. It is one of the important materials in industry. foundry beryllium copper contains high beryllium or cobalt. To improve the flow ability of alloy. Add a small amount of silicon and silver to improve conductivity. Its castability is excellent. The addition of beryllium copper now controls the beryllium content below 2%. The role of nickel and cobalt in alloy is to inhibit premature aging of alloy. Beryllium copper is mainly used as various advanced elasticity components. Especially various components that require good conductivity, corrosion resistance, wear resistance, cold resistance, and no magnetism - widely used as bellows, diaphragms, bellows, microswitches, etc. foundry beryllium copper is used for explosion-proof tools, various abrasives, 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.
