Tungsten Powder Description
Tungsten Powder (W Powder) features high purity, small particle size, small bulk density, uniform particles, high activity, large specific surface area, and extremely low oxygen content after the powder is treated with inert gas. It is easy to disperse and used in industries, currently widely used in aerospace alloys, electronic packaging alloys, electrode materials, microelectronic films, sintering aids, protective coatings, gas sensor electrodes, etc.
Tungsten powder is of high density and high melting point. It is spheroidal in shape and Gray in color. Tungsten powder has superior density properties to lead powder, is non-toxic, and is much safer to handle.

Tungsten powder Properties
• High Melting Point: Tungsten has the highest melting point of all metals, at approximately 3,422°C (6,192°F).
• High Density: Tungsten powder is extremely dense, with a density of about 19.3 g/cm³, which is nearly twice that of lead. This property is beneficial in applications requiring high mass in a small volume, such as radiation shielding and counterweights.
• High Hardness and Strength: Tungsten powder exhibits high hardness and strength, making it valuable for producing cutting tools, abrasives, and wear-resistant materials.
• Thermal and Electrical Conductivity
• Corrosion Resistance: Tungsten powder is highly resistant to corrosion and oxidation, particularly at high temperatures.
• Chemical Stability: Tungsten is chemically stable and inert, not react easily with other substances.
Tungsten powder Application
Tungsten powder is mainly used in the production of weight fillers, radiation shielding fillers, induction accelerators, etc. The thin film surface of its polymer mixture makes it suitable for radiation protection. It is also an ideal heavy metal filler for injection-molding applications due to its large particle size. Tungsten powder is suitable for applications in the metal spray industry.
Tungsten powder is used in aerospace alloys, electronic packaging alloys, electrode materials, microelectronic films, sintering aids, protective coatings, and gas sensor electrodes.
