Tungsten bar (English name: Tungsten Bar) is also called tungsten alloy bar. Tungsten alloy rod (WMoNiFe) and Anviloy 1150 are made of metal powder at a specific high temperature, using a special high-temperature powder metallurgy technology. In this way, the tungsten alloy rod material has low thermal expansion coefficient, good thermal conductivity and good material properties.

GRH TEAM
At high temperature, tungsten alloy rod is used as a material with high melting point and low thermal expansion coefficient. The addition of tungsten alloying elements improves machinability, toughness and weldability. The material's properties are built upon manufacturing tungsten alloy rods to eliminate the problems associated with heat treatment of other tool materials.
