Tungsten Powder Description
Tungsten powder is utilised in a number of industries due to its specific physical properties. Its high density is critical in the production of heavy alloys such as tungsten carbide, which is required for manufacturing cutting tools, mining equipment and armour-piercing projectiles. In addition, its rated heat resistance and conductivity support its use in fabricating electrical and electronic components, including incandescent lamp filaments and heating elements. Furthermore, tungsten powder is employed in the manufacture of radiation shielding materials for both medical and industrial applications.
