Products Description


CoCrMo
CoCrMo alloy (cobalt chromium molybdenum) is a kind of cobalt-based alloy, and also a kind of commonly known as Stellite alloy. It is a kind of cobalt-based alloy that can resist wear and corrosion. The initial cobalt-based alloy was a cobalt-chromium binary alloy, which was later developed into a cobalt-chromium-tungsten ternary composition, and then a cobalt-chromium-molybdenum alloy was developed later. Cobalt-chromium-molybdenum alloy is mainly composed of cobalt, containing a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, and occasionally also contains iron alloys. According to the different components in the alloy, they can be made into welding wire, powder used for hard surface surfacing, thermal spraying, spray welding and other processes, and can also be made into castings and forgings and powder metallurgy parts.


CoCrMo nature
The modulus of elasticity of cobalt-based alloys does not change with the change of maximum tensile strength, and its value is in the range of 220 to 234 GPa, which is higher than that of other materials such as stainless steel.
CoCrMo alloys are particularly susceptible to work hardening, so the same manufacturing process as other metals cannot be used, but vacuum precision casting is required. Controlling the mold temperature can control the grain size of the casting. The formation of coarse grains at higher temperatures will reduce the strength, but it will also precipitate farther and larger carbides and reduce the brittleness of the material.
Due to the limited resources of Co and the difficulty of production and preparation, this series of alloys has not been widely promoted and used like nickel-based alloys.
