Cobalt-based Alloy
Cobalt-based Alloy has good hardness of high and normal temperature，excellent high-temperature intensity, anti-fatigue properties in high-temperature, thermal shock resistance and good performance of the impact of anti-oxidation and corrosion resistance, with the properties of high wear resistance of wear tablet and the good anti-intermetallic wear. Mainly used its wear resistance, corrosion resistance, high temperature resistance, impact resistance in the manufacture, repair and pre-protection of all kinds spare parts under the mining conditions.
