Tungsten Molybdenum Has Important Applications In Various Industries

May 25, 2020

Tungsten molybdenum is an important additive element of steel and nonferrous metals. Tungsten steel and molybdenum steel have high strength, hardness, corrosion resistance and long service life at room temperature and high temperature. Adding tungsten and molybdenum to nonferrous metal alloys can also improve the strength, wear resistance and corrosion resistance of the alloys. Tungsten carbide is one of the most widely used cemented carbide materials at present. It has high hardness and red hardness. It is widely used in cutting, wear-resisting parts, molds, measuring tools and mining equipment. At present, the consumption of tungsten in this aspect accounts for more than 40% of its total consumption. With the development of rocket and missile technology, more stringent requirements have been put forward for materials. Tungsten molybdenum has also developed a new application way in this respect. Such as rocket engine nozzles and high heat flow components, as well as satellites, spacecraft and space shuttle important structural materials.

In the atomic energy industry, tungsten and molybdenum are indispensable addition elements and high temperature resistant parts of the cladding material alloy. In the electronic industry and the industry of electric light source, tungsten, molybdenum and their alloys are used to manufacture various welding electrodes and other structural elements, in the mechanical industry and the electrical industry, they are used to manufacture spring wires in various precision instruments, heating elements in high-temperature resistors, spiral coils for vacuum spraying and plating, and so on.

In the thermocouple industry, the tungsten-rhenium thermocouple has the ideal high temperature mechanical and thermoelectric properties. It can measure the temperature range of -15.6℃ ~ -3103℃, and high accuracy (error is only 6.6℃), fast reaction (response time is 1/4 second) in addition, tungsten and molybdenum compounds in the textile, medicine, glass and other industries also have a wide range of applications.

China's tungsten ore reserves account for more than 50% of the world's, molybdenum reserves are also quite rich, in the tungsten molybdenum powder metallurgy, we have made great achievements.
