Tungsten and molybdenum are rare, very low levels in the crust. Many superior performance make it increasingly wide range of applications. Tungsten and molybdenum metal having a melting point higher than the major, high-strength, high hardness, good electrical and thermal conductivity and corrosion resistance and a series of excellent performance and is ideal for high temperature and high strength structural materials. 

 

Tungsten and molybdenum are important elements of steel and non-ferrous metals added. Tungsten and molybdenum steel at room temperature and high temperature have a very high strength, hardness and corrosion resistance and long service life. Adding non-ferrous alloys of tungsten and molybdenum, can improve the strength of the alloy, wear resistance and corrosion resistance. 

 

Tungsten carbide is the most widely used cemented carbide material, he has high hardness and red hardness, commonly used for cutting, wear parts, dies, gauges, and of mining equipment. Currently, tungsten consumption in this area accounted for more than 40% of total consumption. 

 

With the development of rocket missile technology, materials made ​​more stringent requirements. Tungsten and MoSi2 in this area has also developed new ways to apply; nozzles and high heat flux components such as rocket engines, as well as satellites, spacecraft and space shuttles important structural materials. 

 

In the atomic energy industry, tungsten and MoSi2 alloys as sheath material indispensable to add elements and high temperature components. In the electronics industry and the electric light industry, tungsten, molybdenum and alloys used in the manufacture of welding electrodes and other structural elements in the industrial machinery and electrical industry, used in the manufacture of precision instruments in the spring wire, high temperature resistance in a heating element, a helical coil with a vacuum deposition boat, and the like. 

 

Thermal industry thermocouples, tungsten rhenium thermocouple has an ideal temperature mechanical properties and thermal properties. It can measure the temperature range of -15.6 ℃ ~ -3103 ℃, and accuracy (error of only 6.6 ℃), fast response (response time is 1/4 seconds) 

 

In addition, tungsten and molybdenum compounds in textiles, pharmaceuticals, glass and other industries also have a wide range of uses. 

 

Electric vacuum using tungsten and molybdenum products production is an important part of the metallurgy of tungsten and molybdenum is important to discuss the textbook content. 

 

Tungsten ore reserves of more than 50% of the world, is also abundant reserves MoSi2, tungsten and molybdenum in powder metallurgy, we have made great achievements, but, compared with the industrialized countries of the world there is a great gap, we should redouble our efforts in the shortest possible period of time, so that our tungsten and molybdenum products into the world market, catch up and surpass the world's advanced level.
