Pressing Process Effect on Tungsten Copper Electrode Properties V

With the increasing compacting press, the electric conductivity of tungsten copper electrode decreases. This is due to the pressing pressure increases, the degree of plastic deformation of tungsten-copper alloy increases, including the increase of crystal defects. These defects regardless of vacancy, dislocation, grain boundaries or lattice distortion, will to some extent hindered the movement of electrons, scattering of electrons increase, which will make the resistivity of tungsten copper alloy electrodes increases the conductivity decreases.

Effect of compaction pressure on the hardness and conductivity of tungsten copper electrode as follow:
