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.
Cobalt-Based Investment Castings
There are a wide variety of cobalt alloys, each offering unique features and benefits. The most commonly cast air-melted cobalt alloys are:
Cobalt Alloy 6 – AMS 5387
- Most commonly used; performs well in general wear situations
- High resistance to chemical deprivation in various temperature ranges
- Maintains hardness up to 900°F
- Holds up well to impact and resistant to surface pitting
Cobalt Alloy 3
- High carbon content makes it resistant to abrasion and erosion
Cobalt Alloy 21 – AMS 5385
- Lower ductility
- Excellent resistance to thermal and mechanical shock
Cobalt Alloy 31 – AMS 5382
- High tensile and creep properties
- Highly resistant to wear in metal-on-metal applications
- Functions well at high temperatures
