Precision-ground W70Cu Rod

The W70Cu rod (CuW70 tungsten-copper rod) is a composite material made of precision tungsten (W) and copper (Cu) 70%. Through various manufacturing processes, which may include powder metallurgy, isostatic pressing, high-temperature sintering, and copper infiltration refining, W70Cu rods are made. Combining the superior physical attributes of tungsten and copper, with the ability to meet high-precision dimensions and surface requirements through processes like precision grinding, makes this composite a highly sought-after material in high-end manufacturing. The precision-ground W70Cu rod is one of the special allied materials. It is distinguished from the other materials by its combination of high density, high strength, superior conductivity, and remarkable resistance to extreme temperatures and arcing. All these attributes make it an indispensable material in many high-tech industries, especially in high-voltage electric devices, precision electric discharge machining, and aerospace heat dissipation.
