Tungsten Copper Alloy

Tungsten copper alloy (W-Cu) is the composite of tungsten and copper which own it excellent performance of tungsten and copper.

Tungsten copper may be used as an electrical contact material. In the most severe applications associated with power generation and transmission the switch may be totally immersed in oil. In these cases there is no advantage in using the tarnish resistant silver-based materials, as oxidation is prevented by the exclusion of air. Tungsten copper contacts are widely used in these cases, the selection of the grade used being dependent on the relative importance of conductivity and arc resistance.

Taking the construction group company as the development blueprint, Jingxin Group will focus on the development of cemented carbide, mining machinery, engineering tools, auto parts, new energy, and leisure sports equipment industries.
