Tungsten Copper Bar For Resistance Welding Electrode

Tungsten copper bar for resistance welding electrode combines the good performance of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, large specific gravity, good electrical and thermal conductivity, easy processing, and its dings such as sweating and high hardness of tungsten. High melting point, anti-adhesion characteristics, often used to do a certain wear resistance, high and low temperature welding, butt welding electrodes.
