The application of tungsten
Tungsten is widely used, the most common being tungsten carbide (WC) carbide. Such cemented carbides are used as durable metals in the metalworking, mining, oil extraction and construction industries. In addition, the tungsten wire is also widely used in electric bulbs and vacuum tubes. Tungsten is also commonly used as a tungsten electrode. Tungsten can be drawn into very fine threads and has a very high melting point. Other applications include:
Because of its very high melting point, tungsten is commonly used in aviation and high temperature environments such as electronics, heating and welding (e.g Tungsten gas shielded arc welding).
Tungsten is very hard and compact, making it ideal for heavy metal alloys used in armor, heat sinks and high-density applications such as heavy weights, balance weights, ships and aircraft.
Superalloys containing tungsten (Hastelloy, stellite, etc.) are used to make turbine blades, durable parts and protective coatings.
Tungsten is used instead of lead in bullets.
Tungsten compounds are used as catalysts, inorganic colors. Tungsten disulfide is a high-temperature lubricant that remains stable at 500 °C.
Alloys of tungsten with nickel, iron and cobalt are used to make heavy alloys that replace depleted uranium in kinetic energy bombs.
Tungsten is the connector between the front circuits in integrated circuits. The contact holes are eroded in the silica insulator, tungsten is injected, and ground down to connect the triode. A typical contact hole can be as small as 65 nanometers.
Tungsten carbide is one of the hardest substances and is used in machine tools and abrasives. Tungsten carbide is the most common and often the best material in abrasive and rotary tools.

Tungsten is a shielding substance in radiology. Tungsten containers/ Tungsten shields are commonly used to transport fluorodeoxyglucose because the high energy fluorine 18 in fluorodeoxyglucose makes lead containers unusable.
Others: Tungsten oxide is used in ceramic glazes, calcium or magnesium tungsten is commonly used in phosphors. Tungsten crystals are used as scintillation detectors in nuclear physics and medicine. Tungsten is used as an X-ray target and as a heater in electronic furnaces. Tungsten-containing salts are used in the chemical and leather industries.
Bronze tungsten oxide is used in painting. Tungsten carbide is used in jewelry because of its low sensitivity, and because it's so hard it won't scratch like other polished metals. The hyun of some instruments uses tungsten wire.
