TUNGSTEN POWDERS

Tungsten powders are available in multiple parameters – size, distribution of particle diameters and bulk density. The product is prepared and delivered according to client’s technical requirements.

How tungsten powder is made?

Powder metallurgy is made out of three main stages:

  • production of powders;
  • cold moulding;
  • sintering;

Tungsten powders are formed mechanically. That means, the powder is made by

physically breaking and crushing solid material into fine particles, using abrasive materials, milling and grinding. In the next step, the powder is formed and pressed to condense its molecular structure.

Moulded part is then sintered, in other words it is exposed to thermal processing, which changes its physiochemical characteristics, making the particles join together. Final treatment consists of processes such as casting and rolling. This operation closes off the voids in the microstructure, which positively influences tensile strength and corrosion resistance. As a result, we have a uniform and well fused product.

Tungsten powder use

Spherical tungsten powders are popular for 3D printing, but are also used for other techniques – including metal injection molding (MIM). Tungsten powders allow to produce products of complex geometry in one component with very high accuracy and precision.

Due to strength and high temperature resistance, tungsten powders are used in production of tungsten penetrators for APFSDS projectiles.
