Beryllium copper alloy is the best performance of all copper alloy., Beryllium copper has higher strength, hardness, less elastic hysteresis, flexible higher stability, better wear resistance, better corrosion resistance, and better cool temperature, better fatigue resistance, better electrical conductivity and betterthermal conductivity and elastic limit than any other copper alloys. Additionally, there are non-magnetic, impact properties without sparks, etc.. Beryllium copper alloy are widely used in aviation, electronics, telecommunications, machinery, petroleum, chemical, automotive and home appliances industries. Beryllium copper alloy is used to make important and key components, such as the film plate, diaphragm, bellows, spring washers, micro-motor brushes and commutator, electric connectors, switches, contacts, clock parts, audio components, bearing, gear , automobile electronics, plastic mold, welding electrodes, submarine cables, pressure shell, no spark tools and so on

Application standards: ASTMB 196M-97, and ASTMB 441-96
