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.
