Cobalt gives alloys increased resistance to wear, corrosion, and heat, proving them with a longer service life and enhancing reliability.
Combining cobalt with other metals
Cobalt can be combined with other materials by the process of alloying whereby two or more elements, at least one of which is metallic, are combined. Cobalt-containing materials can be conferred with the key physico-chemical properties of cobalt including magnetism, strength at elevated temperatures, and wear and corrosion resistance.
Combining other metals with cobalt
Additional beneficial properties from other metals can be added to those of cobalt, creating a material that is more beneficial for a specific use. For example, adding chromium to cobalt produces a material ideal for prosthesis, which has high wear resistance and is bio-compatible.
Application of cobalt alloys
Cobalt is used in many different alloy applications including wear-resistant alloys, superalloys, powder metallurgy, and hard metal. Cobalt gives these alloys increased resistance to wear, corrosion, and heat, proving them with a longer service life and enhancing reliability. A key sector for cobalt-containing superalloys is aerospace where these properties are vital for reliable and efficient turbines, which helps to ensure passenger safety. Other examples include cobalt alloys for dental and medical devices where cobalt confers biocompatibility.
