Since the two metals of tungsten and copper are incompatible with each other, the tungsten-copper alloy has low expansion property of tungsten, abrasion resistance, corrosion resistance, high electrical and thermal conductivity with copper, and is suitable for various mechanical processes.

Tungsten-copper alloy can be processed and dimensioned according to user requirements. Tungsten-copper alloys are generally processed by powder metallurgy. Powder-batch mixing-press molding-sintering tungsten-copper alloy has high temperature resistance, arc ablation resistance, high specific gravity and high electrical and thermal conductivity, and is easy to be machined for welding electrodes. 

Tungsten-copper is a composite material which is refined by the techniques of high-purity tungsten powder and the plasticity and high electrical conductivity of high-purity copper powder. It is refined by hydrostatic molding, high-temperature sintering and copper infiltration. Good arc breaking performance, good electrical and thermal conductivity, low thermal expansion, high temperature, no softening, high strength, high density, high hardness.

Tungsten-copper electronic packaging material: not only has the low expansion property of tungsten, but also has the high thermal conductivity of copper. The thermal expansion coefficient and electrical and thermal conductivity can be changed by adjusting the composition of the material, thereby facilitating the use of the material. Tungsten-copper alloy tubes are widely used in cemented carbides and insoluble metals. Since the tungsten-copper alloy is easy to machine, the use of the tungsten-copper tube plays a large role in the case where the surface needs to be easily machined and the inner diameter is required to be small.
