Cobalt based alloy is a kind of alloy with cobalt as the main component, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, lanthanum and other alloying elements, occasionally also containing iron. According to the composition of the alloy, they can be made into welding wire, powder for hard surface surfacing, thermal spraying, spray welding and other processes, can also be made into casting and forging parts and powder metallurgy parts.
