Cobalt Alloys Powder Characteristics

Spherical Cobalt-Based Alloys Powder (CoCrMoW) is a kind of hard alloy that can resist various types of wear and corrosion as well as high-temperature oxidation. It is commonly known as cobalt-chrome-tungsten (molybdenum) or Stellite( an alloy invented by Elwood Haynes in 1907). Cobalt-based alloys are alloys in which cobalt is the principal component and contains significant amounts of nickel, chromium, tungsten, and small amounts of molybdenum, niobium, tantalum, titanium, lanthanum, and occasionally iron. Depending on the composition of the alloy, they can be made into welding wire, powder for hard surfacing, thermal spraying, spray welding, and other processes, as well as cast and forged parts and powder metallurgy parts.

Cobalt Alloys Powder Applicable Processes

According to its application, cobalt base alloy can be divided into the cobalt-base wear-resistant alloy, cobalt-base high-temperature resistant alloy, cobalt-base wear resistance, and aqueous solution corrosion alloy. General working conditions, in fact, are both wear resistance and high-temperature resistance or wear resistance and corrosion resistance, some working conditions may also require high-temperature resistance and wear resistance and corrosion resistance, and the more complex working conditions, the more can reflect the advantages of cobalt-based alloy.

Cobalt Alloys Powder Application

General cobalt-based superalloys lack a uniform strengthening phase. Although the strength at medium temperature is low (only 50-75% of that of nickel-based alloys), they have high strength, good thermal fatigue resistance, thermal corrosion resistance, and abrasion resistance at higher than 980, and good weldability. It is suitable for the production of guide vane and nozzle guide vane of aviation jet engines, industrial gas turbines, naval gas turbines, diesel nozzles, etc.

Cobalt Alloys Powder Storage and Packaging

Spherical Cobalt-Based Alloys Powder (CoCrMoW) should be stored in a sealed container in a dry and cool place, and should not be exposed to air for an extended period of time. We offer vacuum-sealed packaging including 100g/bag, 500g/bag, 1kg/bag, and 25kg/drum, or we can offer customized packaging as per specific requirements.
