Copper Tungsten Resistance welding electrode: It combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, large specific gravity, good electrical conductivity, good thermal conductivity, easy cutting, and has the characteristics of sweating, etc., due to the high hardness of tungsten. High melting point and anti-adhesion characteristics a
Tungsten-copper alloys have a wide range of applications, mainly for the manufacture of high-voltage electrical switch contacts for arc ablation and high-temperature components such as rocket nozzle throat linings and tail rudders, as well as electrodes for electromachining, high temperature molds and others. Where electrical and thermal conductivity and high temperature use are required.
Copper Tungsten Resistance welding electrode: It combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, large specific gravity, good electrical conductivity, good thermal conductivity, easy cutting, and has the characteristics of sweating, etc., due to the high hardness of tungsten. High melting point and anti-adhesion characteristics are often used for projection welding and butt welding electrodes with certain wear resistance and high temperature resistance.
