Tungsten metal powder is a fine particulate form of tungsten used as a raw material in various industrial applications. Its unique properties like high density, strength, corrosion resistance and high melting point make it an important engineering material.

Composition and Manufacturing

Elemental CompositionPure tungsten (W) or an alloy with other metals
Production ProcessMilled from tungsten rods or reduced from tungsten oxides
Particle SizesRanging from 1 micron to 150 microns typically
Purity GradesFrom 99% to 99.995% pure tungsten

Tungsten powder is produced through various processes like hydrogen reduction, milling, or thermal plasma spheroidization to achieve desired shape and purity.
