More info

Tungsten powder is known for its high density, melting point, and hardness. It is produced through the reduction of tungsten trioxide or ammonium paratungstate (APT), with the purity of the product depending on factors such as the temperature of the reduction reaction, the amount of reducing agent, the movement of the container, and the speed of the gas flow.

HM is a reputable supplier of tungsten powders that can be supplied in various particle size ranges (0.4-25 μm). The available purities range from commercial grade to high purity levels, including 3N (99.9% pure), 3N5 (99.95% pure), 4N (99.99% pure), and 4N5 (99.995% pure).

Tungsten Powder Applications

Tungsten powder serves as the primary raw material for manufacturing powdered metallurgy tungsten products and tungsten alloys.
Pure tungsten powder can be processed into wires, rods, tubes, plates, and other machined materials, as well as products of specific shapes.
When mixed with other metal powders, tungsten powder can be used to create a variety of tungsten alloys, such as tungsten-molybdenum alloys, tungsten-rhenium alloys, tungsten-copper alloys, and high-density tungsten alloys.
Tungsten powder is mainly used in the production of weight fillers, radiation shielding fillers, induction accelerators, etc.
Tungsten powder is suitable for applications in the metal spray industry.
