Details
Tungsten-copper alloy is combined with some advantages of tungsten and copper, and is characterized by high temperature resistance, arc ablation resistance, high specific gravity and high strength. The product may be used as the contactor high medium-voltage electric switches, heat dissipation/electron emission material and welding electrodes of electronic components, household appliances and clock parts. It is comprehensively applied in the industries like machinery, electronics, metallurgy and aerospace.
