According to supplied drawing and metal compositions, many kinds of parts can be made by investment casting and powder metallurgy methods, such as valve seat insert, forging mould, valve cage and Cobalt Chrome Alloy series 3, 4, 6, 12, 21, 23, 25, 27, 30, 31, 36, as well as Co# 400, Umco 50s cobalt based alloy products.
Product Features
1. 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, acid liquid and any other mediums.
