W80Cu20 Tungsten-Copper Alloy Bar
Tungsten Copper Alloy is of tungsten and copper, which is formed by isostatic pressing, high temperature sintering, tungsten framework and copper infiltration.
The comprehensive advantages of Tungsten Copper Alloy high temperature resistance, arc erosion, high strength, heavy, conductivity, good thermal conductivity, easy machining, and has the characteristics of transpiration cooling, because of the characteristics of tungsten high hardness, high melting point, anti adhesion, it is usually used to do a certain wear resistance, high temperature resistance projection welding, butt welding electrode.
