Tungsten (W) Counter Weight

Tungsten counter weigt introduction

Tungsten is a highly valued metal known for its exceptional properties and wide range of applications. It is a grayish-white transition metal with the highest melting point of all elements, making it extremely robust and resistant to high temperatures. Tungsten is also one of the densest elements, known for its exceptional hardness and strength.

This metal has excellent electrical and thermal conductivity, along with low thermal expansion, which makes it ideal for various electrical and electronic applications. Tungsten is commonly used in the manufacturing of filaments for incandescent light bulbs, electrical contacts, and high-temperature heating elements. Its unique combination of strength and density makes it a preferred choice for producing heavy alloys, such as high-speed steel and superalloys used in aircraft and turbine engines.

Tungsten s high density also makes it an essential component in radiation shielding and ballast applications. Additionally, tungsten is widely used in the production of cemented carbides, which are extremely hard and wear-resistant materials used in cutting tools, mining equipment, and drilling bits.

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 counter weigt 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 counter weigt.

Tungsten counter weigt are mainly used as cathode, conductive parts, heat resistant parts and other devices in electronic products and industrial equipment. W counter weigt are also the raw material for small size tungsten crucibles.
