Description of Beryllium Copper Wire
Beryllium copper (BeCu) also known as Copper Beryllium and Beryllium bronze, is one of the highest strength copper-based alloys available on the market today. The industrial-grade of beryllium copper contains 0.4%-0.2% beryllium. The alloys are also non-magnetic and non-sparking. Therefore, they provide many ideal materials in many applications. Moreover, because copper-beryllium performs well in most metalworking and joining processes, special configurations can be produced economically.
Beryllium copper wire, which has good electrical conductivity, thermal conductivity, corrosion resistance, and processing properties, can be welded and brazed.
