Tungsten Metal W CAS 7440-33-7 For Special Steel And Tungsten Carbide
Name: Tungsten Metal, Tungsten powder Molecular formula: W
CAS: 7440-33-7 Molecular weight: 183.84
Description: Tungsten is a silvery white metal, which looks like steel. Tungsten has high melting point, low vapor pressure and low evaporation rate. The chemical properties of tungsten are very stable. It does not react with air and water at normal temperature. When it is not heated, hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid and aqua regia of any concentration do not work on tungsten. Tungsten is the most abundant element found on the earth. There is no single substance in nature. Its main source and ore, the main ore known as wolframite or tungsten tetroxide and iron, manganese and tungsten oxide mixture.

Used: Tungsten is mainly used to make heavy metal alloy steel and tungsten carbide hard materials. Tungsten is widely used, the most common is tungsten carbide (WC). Such cemented carbides are often used as durable metals in metal processing, mining, oil extraction and construction industries. In addition, tungsten wire is widely used in light bulb and vacuum tube. Tungsten is also commonly used as an electrode. Tungsten is very hard and compact, so it is ideal to make heavy metal alloy. Such alloy is used in armor, radiator and high-density applications such as ballast, counterweight, ship and aircraft ballast. Because tungsten is very tight, darts tend to contain 80 to 97 percent of tungsten. High speed steel contains tungsten, sometimes 18%. The superalloys used to make turbine blades, durable parts and protective layers contain tungsten (Hastelloy, Stellite, etc.). Tungsten compounds can be used as catalysts.
