1. High-temperature resistance
The strength keeps stable up to 800℃ and it can even be 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 has exceptional wear
and galling resistance.
3. Corrosion resistance
This excellent 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 process. It has better strength than casting
parts, better granule structure, and avoids the troubles caused by
casting defects.
