Tungsten powder is an explosive, toxic material with a high degree of flammability.
Tungsten powder is classified according to the type and size of particles, bulk density, purity of the feedstock, etc. Aluminum, lanthanum and other elements are used as additives to improve performance. The main grades of tungsten powder: normal (PV), low-active (PVN), high-active (PVV), technical (PVT)
Tungsten powder is a raw material for the production of tungsten, as well as tungsten rolled products. Using powder metallurgy methods, sintered rods are made of tungsten powder, which serve as material for producing tungsten rolled products: electrodes, rods, sheets, wire. Tungsten powder is used in metallurgy for the production of hard, high-temperature alloys, as well as special steels
