Beryllium copper is based on beryllium as the main alloy of copper alloy, also known as beryllium bronze. It is the best performance of copper alloy in the high-performance elastic material, a high strength, flexibility, hardness, fatigue strength, elastic lag small, corrosion resistance, wear resistance, cold, high conductivity, non-magnetic, impact does not produce sparks A series of excellent physical, chemical and mechanical properties. Beryllium copper tape used in micro-motor brush, cell phone, battery.
