Intorduction of Tungsten Copper Alloy

Tungsten copper alloy product is a sintered tungsten copper material manufactured by powder metallurgy. It forms dense composite offering hardness, wear resistance and a high softening temperature of tungsten combined with the good electrical conductivity of copper.

Tungsten copper alloy 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 alloy contacts are widely used in these cases, the selection of the grade used being dependent on the relative importance of conductivity and arc resistance.
