Beryllium copper Alloy is mainly made from Beryllium and called “beryllium bronze” as well. It possesses the best performance among all copper alloys such as elasticity, high strength, hardness, fatigue strength, low in elastic hysteresis, corrosion resistance, war-proof, hardiness, high-conductivity, non-magnetic, no spark generated in impact and other superior physical, chemical and mechanical performances. Beryllium bronze has been applied to the fabrication of elastic elements like film box, film, corrugated pipe , micro-switches,…etc. that also require good attributes such as conductivity, anti-resistance, wear-proof, hardiness, non-magnetic. Beryllium bronze can also be used to make explosion-proof tools, various kinds of dies, bearings, bearing shell, bushing, gears and various electrodes.
