Cobalt Investment Castings

Cast cobalt alloys are highly revered for protecting against oxidization (rust) by a passivating oxide film. The cobalt casting method provides enhanced corrosion-, heat-, and wear-resistance, delivering superior results for various industries, including medical, aerospace, automotive, military, and other applications where oxidization is problematic and high strength is critical.

At Aero Metals, we work with you to produce cobalt investment castings that meet your project specifications. Check out our featured cast parts gallery for examples of our AMS 5387 and 5382 cast cobalt alloys, or request a quote today.

Cobalt Casting Options

Aero Metals offers various cobalt investment casting material options to meet your project requirements, each offering unique features and benefits. The most commonly cast air-melted cobalt alloys include:

Cobalt Alloy 6 – AMS 5387

• Most frequently 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 resists 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

Cobalt Investment Casting Applications

Aero Metals produces cobalt-based investment castings for customers in various industries where part wear, harsh working conditions, high maintenance costs, and costly downtime can be problematic for the end user. This makes cobalt-based alloy castings useful in numerous industries, including:

• Aerospace
• Automotive
• Military
• Medical

In the medical industry, cobalt-based investment castings 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 and thermal fatigue resistance.
