Cobalt alloy investment castings are the casting parts poured by lost wax investment casting process. Cobalt-based alloys are a group of metal alloys based on cobalt as the main composition, containing a considerable amount of nickel, chromium, tungsten and a small amount of other alloying elements such as molybdenum, niobium, tantalum, titanium, lanthanum, and occasionally iron. According to the different composition of the alloy, the cobalt-based alloy can be made into welding wire, and the powder can be used for hard-surface welding, thermal spraying, spray welding and other processes, and it can also be made into castings, forgings and powder metallurgy parts. Cobalt-based alloy is a hard alloy that can withstand various types of wear, corrosion and high temperature oxidation. Classified by the end usage, cobalt-based alloys can be divided into cobalt-based wear-resistant alloys, cobalt-based high-temperature alloys and cobalt-based solution corrosion-resistant alloys. In general operating conditions, they are both wear-resistant and high-temperature resistant or wear-resistant and corrosion-resistant.
