Tungsten rod is also called tungsten alloy rod. Tungsten alloy rods (WMoNiFe) and Anviloy 1150 are made of metal powder at a particular high temperature, using a special high-temperature powder metallurgy technology. Thus, the thermal expansion coefficient of the material is low, the thermal conductivity is good and the material properties are good. At high temperatures, tungsten alloy rods are used as a material with high melting point and low thermal expansion coefficient. The addition of tungsten alloy improves machinability, toughness and welding. The performance of the material is based on the manufacture of tungsten alloy rods to eliminate the heat treatment associated with other tool materials.

Tungsten has special properties, such as low thermal expansion and good thermal conductivity, anti resistive enough, high modulus of elasticity. As a result, tungsten rods have been widely used in various fields, such as support lines, lead-in lines, printers, various kinds of electrodes and quartz furnaces, filament, high speed tools, automotive products, sputtering targets. Application in glass melting: High temperature furnace heater, structure parts, welding electrode, filament, weapons for X-37B. The processing method is sintering, forging, rotary forging, rolling, polishing. In the military field, when the aircraft reaches the target, it quickly put ammunition. Modern ammunition is not the same as before, before the launch of the ammunition is very heavy fire explosives, such as Tomahawk missiles with 450 kg of TNT explosives, high explosives. Modern fighters do not take much explosives, it changes a new concept to hit target, it no longer use the traditional ammunition, but put on a metal rods made of metal tungsten, which is the tungsten rod.
