Production process of Tungsten Copper Bar

Tungsten-copper is an alloy of tungsten and copper. Tungsten-copper alloy is made of fine tungsten and copper powder, which is refined by the process of isostatic molding, high temperature sintering of tungsten skeleton and copper dissolution through the first-class immersion sintering process.

Applications of Tungsten Copper Bar

  1. Resistance welding electrode: tungst-copper alloy combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, specific weight, good electrical conductivity, good thermal conductivity, easy to machining, and has the characteristics of sweating and cooling. Because tungsten copper alloy has the characteristics of high hardness, high melting point and anti-adhesion of tungsten, it is often used to make convex welding and butt welding electrodes with certain wear resistance and high temperature resistance.
