Suitable for high-value parts requiring dense coatings
Product description
73WC-NiCr is a tungsten-carbide powder with about 73% WC held in a NiCr matrix, made by Huayin for HVOF. The WC phase delivers very high hardness and solid-particle wear resistance, while the NiCr matrix adds the corrosion resistance that a plain cobalt binder sometimes cannot provide, especially in chemically aggressive or humid service.
With its balance of hardness and corrosion resistance, the material is often chosen for high-value parts needing a dense, durable coating under combined wear and corrosion. Particle size and spray settings should match the HVOF gun in use; CQ advises on a suitable size range to achieve a low-porosity, well-bonded coating.
Used on pump shafts, sleeves, valves, seal rings, rolls and parts needing solid-particle wear resistance while retaining corrosion protection.
