Cobalt-based alloys
Cobalt-based alloys have a 50% percentage of cobalt, which provides this material with great resistance to abrasion at high temperatures. Cobalt is similar to nickel from the metallurgical point of view, as it is a hard material that is highly resistant to wear and corrosion, particularly at high temperatures. It is generally used as a component in alloys, due to its corrosion resistance as well as to its magnetic properties.
This type of alloy is hard to manufacture, due precisely to its high wear resistance. Cobalt is usually employed as a surface hard material in industrial areas with critical wear. It also stands out due to its mechanical properties at high temperatures, and is found in many construction alloys to increase ductility at high temperatures.
This type of alloys are found in the following fields:
- aeronautical industry
- marine industry
- chemical process industry
- industrial gas turbines
- permanent magnets or superalloys
