Copper tungsten alloy products for electrode or EDM
Why choose Copper Tungsten products?
Copper tungsten alloy (W-Cu) is a composite of tungsten and copper which own its excellent performance of tungsten and copper.
Copper tungsten 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 tarnish-resistant silver-based materials, as oxidation is prevented by the exclusion of air. Copper tungsten contacts are widely used in these cases, the selection of the grade used is dependent on the relative importance of conductivity and arc resistance.
