Tungsten Carbide

Application

Cemented tungsten carbide (WC) is used to produce layers resistant to abrasive wear and corrosion in hardfacing, welding, and thermal spraying processes. Tungsten carbide powder can be blended as a hard-phase filler material in nickel- or iron-based hard composite rods, wires, electrodes, and powder blends, where the metallic matrix may consist of Ni, Co, or alloys in a 30% to 70% or 40% to 60% ratio (in PTA or laser deposition technology). This material is very hard, characterized by high resistance to abrasion, erosion, shearing, and impact. It is used wherever tools or components are exposed to heavy wear, such as when cutting hard materials. Carbide improves the quality of tools and components, gives them a longer service life, and ensures that processes are safe and reliable.
