The main thing
Material
Under normal conditions, tungsten is a hard, heavy, shiny metal with a silvery gray color.
View by manufacturing method
The process of obtaining tungsten goes through the substage of separation of trioxide WO3 from ore concentrates and subsequent reduction to metal powder with hydrogen at a temperature of approx. 700 °C. Due to the high melting point of tungsten, powder metallurgy methods are used to obtain a compact form: the resulting powder is pressed, sintered in a hydrogen atmosphere at a temperature of 1200-1300 ° C, then an electric current is passed through it. The metal is heated to 3000 °C, and sintering occurs into a monolithic material. For subsequent purification and obtaining a single-crystalline form, zone melting is used

Type by purpose
Tungsten sheets are used in conditions of high and extremely high temperatures in the form of equipment for high-temperature furnaces, as well as in the aerospace industry. Tungsten is widely used as shields to attenuate the flow of radioactive radiation in nuclear power, in collimators and radiotherapy. Tungsten rods are used as heaters. Tungsten rods can serve as cathodes for radio tubes, electronic and gas-discharge devices. Tungsten wire is used to make heaters, heat shields and other products. Tungsten rods are blanks from which semi-finished products are subsequently obtained. Tungsten powder is used as an alloying additive or the main component of high-speed and tool steels, as well as wear-resistant and heat-resistant alloys. Non-consumable tungsten electrodes for welding are made from tungsten powder. Pure tungsten electrode is used for welding with alternating current AC. WP tungsten electrodes are designed for welding aluminum, magnesium and their alloys
