What is tungsten copper bar?

Tungsten copper bar is a combination of tungsten and copper. 

The manufacturing process is as follows: press the refractory metal, sinter the pressed compact at a high temperature, and infiltrate it with copper. All this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, high physical Properties: at elevated temperatures, and good electrical and thermal conductivity.

Because of the high eletrical conductivity and low consumption, tungsten copper bars are widely used to make Grid siderod, Lead, Support, Electrode for the Gas discharge lamp.
