Tungsten copper electrode is combined by tungsten and copper, which owns the properties of tungsten and copper. Tungsten copper electrode have good resistance to arc erosion, mechanical wear, contact welding and good conductivity. When switching with moderate contact arcing, the tungsten copper electrode with a high copper content may give the lowest erosion. As arcing severity increases, the tungsten copper with the higher refractory content withstand arc erosion better. Tungsten copper electrode is also used as arcing edges of selector switchblades in transformer tap changers.
Tungsten copper electrode is a good use of high-purity tungsten metal powder and high purity characteristics of the plasticity of copper powder, the advantages of high conductivity, the static pressure molding, high temperature sintering, melting refined copper from the process of composite materials. Tungsten copper electrode owns arc off a good performance, good thermal conductivity, thermal expansion of small, high-temperature non-softening, high-intensity, high-density, high hardness.
