WC-20Cr3C2-7Ni 15-45um Tungsten Carbide Thermal Spray Powder

WC-20Cr3C2-7Ni Tungsten Carbides 15-45um Thermal spray Tungsten Carbide Powder is generally best using High Velocity Oxygen Fuel (HVOF) spray Tungsten Carbide Coating. Choose higher carbide content for higher hardness and resistance to fretting, abrasion and particle erosion. For turbine components: air seals, baffle dampers, nozzle supports, valve seats, struts. For hot crushing rolls, forming dies, forging tools. Service up to 750 °C HVOF Tungsten Carbide Coating.
