Tungsten (W) Particle

Tungsten particle introduction

Tungsten is a metallic element known for its exceptional strength, high melting point, and resistance to heat, wear, and corrosion. It is a dense and hard metal with a silvery-white appearance. Tungsten has the highest melting point of all known elements, making it useful in applications where high temperatures are involved. Additionally, it has excellent electrical and thermal conductivity.
Due to its remarkable properties, tungsten finds a wide range of applications across various industries. It is commonly used in the production of high-speed tools, such as drill bits and cutting tools, where its hardness and heat resistance are crucial. Tungsten is also utilized in the manufacturing of electrical contacts and filaments for incandescent light bulbs and electron emitters in electron microscopes.
Tungsten is an essential component in the production of alloys. It is often alloyed with other metals, such as steel, to enhance their strength and hardness. Tungsten alloys are extensively used in aerospace and defense applications, as well as in the construction of heavy machinery and equipment.

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 particle 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 particle.

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