Product Details
W80Cu20 Machined Copper Tungsten Alloy Spot Welding Head With 220HB
Introduction of Tungsten Copper:
Tungsten copper alloy is featured by high plasticity and high
conductivity. Our tungsten copper alloy rods are processed by high
purity of tungsten powder, copper powder and isostatic techniques.
Both tungsten copper’ s electrical and thermal conductivity are good. Moreover, it owns low
expansion and high temperature resistance.
