What is Cobalt?

Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical.

Benefits of Cobalt

On a global basis, the leading use of cobalt is in rechargeable battery electrodes. Superalloys, which are used to make parts for gas turbine engines, are another major use for cobalt. Cobalt is also used to make airbags in automobiles; catalysts for the petroleum and chemical industries; cemented carbides (also called hardmetals) and diamond tools; corrosion- and wear-resistant alloys; drying agents for paints, varnishes, and inks; dyes and pigments; ground coats for porcelain enamels; high-speed steels; magnetic recording media; magnets; and steel-belted radial tires.

Technical information

Cobalt based alloys (or cobalt based superalloys) are metals whose major mass fraction is cobalt.

The base combination of most cobalt alloys is cobalt-chromium, with chromium acting as a strengthening alloy. Adding tungsten and/or molybdenum can affect strengthening even more. Another common element that is found in many cobalt-based alloys is nickel. Nickel is even more heat resistant than cobalt and is added to widen components’ range of temperature resistance. Generally, cobalt-based alloys display favourable mechanical properties. They are corrosion, wear and heat resistant and are therefore used for components in challenging areas applications, such as hot gas turbines. Cobalt also displays great resistance against sulfides, preventing any sulfidation of the material.
