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, acid liquid 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.
