Tungsten-copper alloys are pseudo-alloys of refractory metals, so tungsten-copper alloys can only be produced by powder metallurgy. The manufacture of tungsten copper tube is a bigger challenge in production process. The inner hole of the tungsten copper rod is processed by wire cutting, which is expensive and cannot be mass-produced.
Tungsten copper tube is a composite material refined by the process of static pressing, high temperature sintering and copper infiltration by utilizing the excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder. Good arc breaking performance, good electrical and thermal conductivity, small thermal expansion, no softening at high temperature, high strength, high density and high hardness. Grade: W-70 (W72, W75, W80).
