Tungsten-copper Alloy Rods with Holes

Alloy rods with holes made of tungsten-copper are composites of tungsten-copper that have a high degree of 

density and hardness, along with good electrical and thermal conductivity and high temperature resistance. The 

tungsten content varies between 50%-90%, and the copper content varies between 10%-50%. These composite 

rods are made using different powder metallurgy techniques like powder preparation, powder pressing, high 

temperature sintering, and copper infiltration. The primary use of these tungsten-copper rods is contact 

production for switches and circuit breakers, because of their resistance to welding and erosion due to arcing. 

Due to their resistance to ablation and thermal shock, they are also suitable for instantaneous applications with 

high temperatures, such as liners of the nozzle throats of rockets and gas rudders of missiles.
