- Product Details
Description
QS Rare Elements, locates in upstate NY, USA, 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 rod 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 W rod.
Tungsten rod are mainly used as cathode, conductive parts, heat resistant parts and other devices in electronic products and industrial equipment. W rod are also the raw material for small size tungsten crucibles.
