Tungsten and Molybdenum Metal Concepts and Uses

Tungsten and molybdenum are two metals that are resistant to high temperatures. Together, tungsten and molybdenum represent one industry, the refractory metals industry. Other refractory metals are niobium, zirconium, titanium and hafnium, instead of one element. It has a great role for industrial development, and now the product is mainly used in the energised electrodes of argon arc welding machines. China is the world's leading producer of tungsten and molybdenum, exports accounted for 80% of the world, widely used in welding, electric light source, electronic devices, chemical industry, mining, metallurgy, shipbuilding, petroleum, aerospace and other industrial fields, the prospects are very broad.

Tungsten and molybdenum and tungsten and molybdenum alloys have good thermal conductivity, electrical conductivity, low coefficient of thermal expansion, high-temperature strength, low vapour pressure and wear-resistant characteristics, and become the electronic and electrical equipment manufacturing industry, metal materials processing industry, glass manufacturing industry, high-temperature furnace structural components manufacturing, aerospace and defence industry application of heavy materials. Molybdenum and molybdenum alloys in the above fields are mainly made by machining, moulding and metal processing and welding.

High-temperature resistant metal, with good thermal conductivity, electrical conductivity, low coefficient of thermal expansion, high-temperature strength, low vapour pressure and wear-resistant and other characteristics, is the electronic and electrical equipment manufacturing industry, metal materials processing industry, glass manufacturing industry, high-temperature furnace structural components manufacturing, aerospace and defence industry applications of important materials.
