Tungsten powder introduction
Tungsten is a remarkable metal known for its exceptional properties, making it highly sought after in various industries. With the highest melting point of all pure metals and one of the highest densities, tungsten possesses remarkable heat resistance and excellent mechanical strength. It has a grayish-white appearance and is incredibly hard, making it one of the toughest metals available. Tungsten also exhibits a low coefficient of thermal expansion and excellent electrical conductivity, making it an ideal choice for high-temperature applications and electrical components.
The manufacturing process of tungsten involves extracting the ore, known as wolframite or scheelite, and then refining it through several steps, including crushing, grinding, and chemical treatment. Tungsten is commonly used in the production of cutting tools, such as drills and saw blades, due to its high hardness and durability. It is also utilized in the aerospace industry for manufacturing turbine blades and rocket nozzles, as well as in electrical applications like filaments for incandescent light bulbs and electrical contacts.
QSAMs tungsten
QS Advanced Materials supplies a wide range of tungsten product. Available materials are high purity tungsten, heavy alloy (W-Ni-Fe, W-Ni-Cu), tungsten carbide (WC), and fake alloys such as W-Cu, W-Ag composite. For shapes, we could provide tungsten products from tungsten high purity powder/grit to common machined products.
Unalloyed tungsten powder are produced from pure tungsten powder, without extra additive. The purity is usually quite high, 99.95%. Compared with alloyed tungsten, pure material is easier to be processed as pure tungsten could be worked by forging, drawing or extruding. Pure tungsten(W) blanks, which are made from W powder by powder metallurgy, are the raw material to process tungsten powder.
Tungsten powder are mainly used as cathode, conductive parts, heat resistant parts and other devices in electronic products and industrial equipment. W powder are also the raw material for small size tungsten crucibles.
