High temperature resistance The strength keeps stable up to 800 and it can even momentarily used at 1200. 2. Wear resistance Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix, it has exceptional wear and galling resistance. 3. Corrosion resistance This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acidliquid and any other mediums. 4. Production process Powder metallurgy pocess, it has better strength than casting parts, better granule structure and avoiding the troubles caused by casting defects.
