Copper Tungsten material produced by Powder Metallurgy wherein sintered skeleton of Tungsten is impregnated with Copper. The erosion pattern of this material is far superior to materials produced by other production techniques. This material maintains quite regular shape under extreme arcing conditions and has only uniform roughening effect without cracks and burn-off droplets.The Tungsten skeleton is protected by impregnated Copper as it provides evaporative cooling effect in extreme arcing conditions, thereby protecting and limiting the temperature rise of the skeleton and preventing disintegration.
