Silver tungsten electrical contacts

Silver tungsten electrical contacts Silver tungsten electrical contacts Silver tungsten electrical contacts

Silver tungsten alloys 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.

High conductivity, thermal conductivity and high melting point of silver and high hardness, welding resistance, small material transfer, and high burning resistance of tungsten are conbined into silver tungsten sintering material.Silver tungsten electrical contact will generate mixed oxides, if it is frequently off in the air, under operating current, so that form the the surface film that can increase the contact resistance.
