Tungsten Silver Alloy with High Conductivity

Tungsten Silver WAg alloy as high-voltage electrical contact material

Silver Tungsten alloy (W-Ag alloy), The silver and tungsten composite group combines the high thermal and electrical conductivity of silver with the high erosion resistance of the high melting tungsten. These materials are also characterized by their high strength and their resistance to welding or sticking. They are principally made by infiltration and the nominal silver content varies from 20-50%. By increasing the amount of tungsten, the hardness and welding is reduced. This composite group of alloys is specially preferred for use in air.

Silver tungsten contain between 25-50% silver and are mainly used for electrical contacts—generally heavy-duty devices subject to high current. Silver tungsten combines the high thermal and electrical conductivity of silver with the arc resistance of tungsten.
