Tungsten rods are also called tungsten alloy rods. Tungsten alloy rods (WMoNiFe) and Anviloy 1150 are made from metal powder at a specific high temperature, using special high-temperature powder metallurgy technology. In this way, the thermal expansion coefficient of the tungsten alloy rod material is low, the thermal conductivity is good, and the material characteristics are good.
At high temperatures, tungsten alloy rods are used as a material with a high melting point and a low coefficient of thermal expansion. The addition of tungsten alloy elements improves workability, toughness and welding. The performance of the material is based on manufacturing tungsten alloy rods to eliminate problems related to heat treatment of other tool materials.
