Tungsten copper electrode is kind of composite metal material and is composed of high purity tungsten powder and good conductivity Cu powder through isostatic pressing and high temperature sintering. Therefore, tungsten copper electrode not only has high melting point(3410℃) and high density (19.34 g/cm3) of W, but also has good conductivity and other advantages of Cu.
