What Field Is Tungsten Used In?

2024-01-05 18:00:06

   The melting point of feldspar tungsten is the highest of all metal elements, its density (19.3 g/cm_) is very high, it is close to gold, and the hardness is also very high, for example, the hardness of tungsten carbide is close to that of diamond. In addition, it has good conductivity and thermal conductivity, small coefficient of expansion and other characteristics, so it is widely used in alloy, electronics, chemical industry and other fields, in which cemented carbide is the largest consumer .


   Alloy field

   • iron and steel

    Tungsten is an important alloy element, which is widely used in the production of various steels. The common tungsten-containing steels are high-speed steels, tungsten steels and tungsten-cobalt magnets with high magnetization and coercivity. Steel is mainly used for manufacturing various tools, such as drill bits, milling cutters, wire drawing dies, female dies and male moulds.

   Tungsten carbide based carbide

   Tungsten carbides have high wear resistance and refractoriness, and their hardness is close to diamond, so they are often used in some cemented carbides. At present, carbide based cemented carbide is the largest consumption area of tungsten. This kind of cemented carbide is a powder metallurgy product made by sintering tungsten carbide micron powder and metal binder (such as cobalt, nickel, molybdenum) in vacuum furnace or hydrogen reduction furnace. carbide-based cemented carbides can be generally divided into carbide-cobalt, carbide-titanium carbide-cobalt, carbide-titanium carbide-tantalum carbide (niobium) cobalt and steel-bonded cemented carbides. These carbide-based cemented carbides are mainly used in the manufacture of cutting tools, mining tools and wire drawing dies.
