Features

AgWC has extremely high harness, good fusion welding resistance and arc erosion resistance. Its contact resistance is slightly higher than AgW. Tungsten carbide decomposes in the arc and the released carbon forms a protective CO gas envelop which suppresses the formation of tungsten oxide and tungstate.
