Tungsten molybdenum alloy is two kinds of high temperature resistant metals, tungsten and molybdenum together, represent an industry, namely refractory metal industry. Other refractory metals are niobium, zirconium, titanium, and hafnium, not an element. For industrial development has a great role, the product is mainly used in the current electrode of argon arc welding machine. China is a major producer of tungsten and molybdenum in the world, and its export accounts for 80% of the world's total. It is widely used in welding, electric light source, electronic devices, chemical industry, mining, metallurgy, shipbuilding, petroleum, aerospace and other industrial fields, with broad prospects.

Tungsten, molybdenum and tungsten, molybdenum alloy with good thermal conductivity, electrical conductivity, low thermal expansion coefficient, high temperature strength, low vapor pressure and wear resistance and other characteristics, and become electronic and electric equipment manufacturing, metal material processing industry, glass manufacturing, high-temperature furnace structural components manufacturing, aerospace and national defense industry applications of heavy materials. The application of molybdenum and molybdenum alloy in the above fields is mainly made by machining, forming, metal processing and welding.

High temperature resistant metal, with good thermal conductivity, electrical conductivity, low thermal expansion coefficient, high temperature strength, low vapor pressure and wear resistance characteristics, is the electronic and electric equipment manufacturing, metal material processing industry, glass manufacturing, high temperature furnace structural components manufacturing, aerospace and national defense industry applications of important materials.
