Physical properties of Copper Tungsten Bar

  • Tungsten copper alloy (tungsten W=70 copper Cu=30)

  • Conductivity% IACS ≥ 42

  • Density=14g/cm3

  • Softening temperature ℃ ≥ 700

  • Tensile strength ≥ 66Mpa

  • Hardness ≥ 184HV

  • Tungsten copper alloy can withstand nearly 2000 ℃ high temperature and high stress. It has the characteristics of high melting point, high hardness, resistance to burning and good resistance to adhesion. The surface finish of electric erosion products is high, the precision is extremely high, and the loss is low.

 

Applications of Copper Tungsten Bar

  • Tungsten copper alloy is widely used as the contact and protective ring of high-voltage and superhydraulic switches and circuit breakers, the material of electric heating block block, the conductive nozzle of automatic submerged arc welding, the nozzle of plasma cutting machine, as well as the welding head of electric welding machine and butt welding machine, the roller welding wheel, as well as the materials for making sealing gas socket electrode and electric spark electrode, spot welding, butt welding, etc
