Cobalt-based alloy Castings
Cobalt is a hard, lustrous, silver-gray metal that is naturally protected against oxidization (rust) by a passivating oxide film. Like nickel, cobalt can only be found in nature in chemically combined forms (natural alloys); pure cobalt can be produced via reductive smelting.
Cobalt alloys are corrosion-resistant, heat-resistant, and wear-resistant. This makes cobalt-based alloy castings useful in numerous industries, including medical, aerospace, automotive, military, and other applications where oxidization is problematic and high strength is critical. In the medical industry, for example, cobalt-based investment castings are used to create orthopedic implants that do not wear down over time. Cobalt alloys are used in high friction bearing environments for their strength and lubricity (or anti-galling quality). In high-temperature environments, such as turbocharger turbines and jet aircraft turbines, cobalt alloys exhibit good creep resistance, as well as resistance to thermal fatigue.
Here are some of the most commonly used cobalt-based alloys our customers use:
CoCrMo
ASTM F75
