High Purity Tungsten Rod
At high temperatures, tungsten alloy bars act as a material with a high melting point and a low coefficient of thermal expansion. The addition of tungsten alloying elements improves machinability, toughness and weldability. The performance of the material is based on the manufacturing of tungsten alloy bars eliminating the problems associated with heat treatment of other cutting tool materials.
Description
Tungsten rods are also called tungsten alloy rods. Tungsten Alloy Bar (WMoNiFe) with Anviloy 1150 is made from metal powder refined at a specific high temperature using special high temperature powder metallurgy technology. Such tungsten alloy bar material has low coefficient of thermal expansion, good thermal conductivity and good material properties.
