220HB CuW75 Copper Tungsten Edm Electrodes Spot Welding Electrodes
CNC 15.6g/cm3 Tungsten Copper Spot Welding Electrodes
Introduction of Tungsten Copper:
Our tungsten copper alloy rods are processed by high purity of tungsten powder, copper powder and isostatic techniques. Tungsten copper alloy has features like high plasticity and high electrical and thermal conductivity and low thermal expansion. Both tungsten copper’ s electrical and thermal conductivity are good. Moreover, it owns low expansion and high temperature resistance.
