The coating has excellent resistance to sliding wear, abrasion and erosion. It is tough and reveals good fatigue and impact resistance. General corrosion resistance is good. Since initial powder particles have porosity, the coating retains micro-pores (0.1 micron size). Thus, thin coatings require sealing for immersion services. This is the most widely used coating among tungsten carbide grades.

Heavy abrasion wear and erosion, sliding wear (impellers, wear plates in milling machines, ball valves and gates, sealing rings, shafts, hydraulic cylinders, centrifugal screens, different types of paper rolls, sink rolls in steel galvanizing, table rolls for heat treatment equipment, wire drawing capstans, chill rolls in acetate film processing, dies of plastic extrusion machines, etc.); widely used as a hard chrome alternative coating.
