1. High temperature resistance

The strength keeps stable up to 800℃ and it can even momentarily used at 1200 ℃.

2. Wear resistance

D ue 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, acid liquid and any other mediums.
