Tungsten copper rod is a kind of round rod. The grade of tungsten copper rod include WD10070、WD10075 and WD10080. the choice of tungsten copper content are depend of the application of tungsten copper rod, but if you do not know the detail application of the material, you can choice the content according to GB/T8320-2003.
Tungsten copper rod is a kind of composite material, which is manufactured by high-purity tungsten powder and high conductivity copper powder with the production process of isostatic pressing, sintering temperature and copper infiltrated.
Tungsten copper rod properties include breaking arc performance, good thermal conductivity, low thermal expansion, in high temperature will not soften, high strength, high density and high hardnes.
Tungsten copper rods are mainly used in resistance welding electrodes, EDM electrodes, high-voltage discharge electrodes and electronic packaging materials.
