Tungsten metal powder is a finely divided form of tungsten, a chemical element with the symbol W and atomic number 74. It comprises tiny tungsten particles in powder form and is a crucial intermediate material in producing various tungsten products.

Appearance: Light or dark grey without obvious lumps or foreign matters.

Production: Tungsten metal powder is typically produced through a reduction process. The most common method involves reducing tungsten oxide (usually tungsten trioxide, WO3) with hydrogen gas (H₂) or carbon (C) at high temperatures. The reduction process results in the formation of tungsten metal powder.

Particle Size: The size of the tungsten metal powder particles can vary depending on the specific manufacturing process and intended applications. Particle sizes can range from nanometers to micrometres.

Purity: Tungsten metal powder is often produced to high purity levels, with impurities kept to a minimum. The purity of the powder is crucial for ensuring the quality of the final tungsten products.

Applications: Tungsten metal powder serves as a feedstock material for the production of various tungsten products, including:

   - Tungsten Alloys: Tungsten metal is commonly alloyed with other elements, such as nickel, iron, and copper, to create high-strength and high-density materials used in aerospace, military, and industrial applications.

   - Tungsten Carbide: Tungsten metal powder can be combined with carbon to produce tungsten carbide, a hard and wear-resistant material used in cutting tools, drilling bits, and industrial machinery.

   - Electrical Contacts: Tungsten metal is used in electrical contacts and filaments, where its high melting point and electrical conductivity make it ideal for applications like light bulbs and electronic components.

   - Radiation Shielding: Due to its high density, tungsten is used in radiation shielding applications, such as in medical and industrial X-ray equipment.

Tungsten metal powder is a versatile material with a wide range of applications, particularly in industries where high-density, high-strength, and high-temperature resistance properties are required. Its production and careful processing are essential to ensure the quality and performance of tungsten-based products.
