China Tungsten Carbide Additive Powder Hard Metal Powder Metallic Powder

99.7% purity coating film metal powder welding rod Cr3C2 chromium carbide powder
Product Application
Thermal spray powder material, grain growth inhibitor for sintering WC/Co hard metRefrigeration Equipment alsand corrosion resistant componentsandetc..Chromium Carbide is a kind of high melting point inorganic materialunder 1000-1100 degrees, which has a good wear-corrosion resistance, oxidation resistance characteristics. Cr3C2 as radicalwithNiCr, and mixed in high temperature to be NiCr-Cr3C2 powder, can be a perfect wear-corrosion resistance thermal spraying material. Adding Cr3C2into the hard metals, it not only can refine WC grain, but also can improve alloy's tensile strength and hardness, and can significantly improve corrosion resistance.
