Tungsten carbide pellet is unique because it is manufactured in a sintering process, whereupon the metal powder is formed under extreme heat and pressure. Tungsten carbide pellet is extremely hard. The manufacturing technique makes these pellets substantially more expensive than other materials, but practically inert. The relative inertness makes tungsten carbide pellet extremely resistant to interaction with various liquids and alloys...
Tungsten carbide pellet is used to be welded onto the surface of the tools or work parts to form a hardened wear-resistant layer in order to provide protection against abrasive wear.
