Pulse Arc Tungsten Copper Electrode

The degree of surface erosion of a pulsed arc tungsten copper electrode is related to the amount or energy of the pulsed arc. For tungsten copper materials, the main form of electrode erosion is evaporation of the electrode material. The effect of pulsed arc on tungsten-copper material is positively correlated with the amount of single-pulse charge transfer and the total pulse charge transfer.

Tungsten Copper Electrode Picture

It is very difficult for a single metal material to have both high melting point, high density, high specific heat capacity and high thermal conductivity. A tungsten copper alloy composed of a high density, a high melting point of tungsten and a high electrical conductivity of copper is used as a switching electrode material.
