Tungsten (W) Pellets
Composition: Tungsten (W, Atomic No. 74) Catalog No.:RF74-PTSPurity:99.95%Typical Lead Time:3 weeks
- 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 pellets 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 blanks, which are made from tungsten powder by powder metallurgy, are the raw material to process W pellets.
Tungsten pellets is usually consumed in vacuum deposition process, to create a thin film of tungsten.
