SILVER TUNGSTEN/SILVER TUNGSTEN CARBIDE

AgW50 has not only good conductivity of Ag, but also the great hardness, good arc erosion resistance, welding resistance, and low material transfer of W. The biggest characteristic of AgW is its high resistance against strong arc.

Besides the properties of AgW, AgWC has greater hardness, and is more superior under strong arc situation.
