Product Description
Ground Tungsten Cooper Rod are ground to precise shape and size to meet American Welding Society RWMA Class 10 specifications with precise tolerances. Copper tungsten has high wear resistance, electrical and thermal conductivity, and corrosion resistance. Copper-tungsten is a high-strength composite of two metals: 70/30 copper-tungsten. It combines the electrical conductivity of copper with the heat and wear resistance of tungsten.
The manufacturing process is: pressing the refractory metal, sintering it at high temperature, and infiltrating it with copper. All of this is done under very tightly controlled conditions.
