Cobalt-Base Alloys for Investment Casting

Cobalt-base alloys are known for their high strength, heat resistance and wear resistance. They are naturally resistant to oxidation and have a high melting point leading to optimal performance in chemical and corrosive environments. Investment casting with cobalt-base alloys is commonly used for aerospace and oil and gas applications because of its creep resistance and resistance to thermal fatigue in high temperature applications.

Investment Casting Cobalt-Base Alloys for High Temperature Applications 

Investment casting allows for tight tolerances and thin walls, making it an exceptional choice for complex parts. Engineered Precision Casting Company, Inc. specializes in complex designs and provides precision investment casting for a range of demanding applications including military, petrochemical, and aerospace. Our investment casting capabilities include prototype to large-scale production runs and we pour sizes up to 16 x 16 in. and 150 lbs.

We have experience pouring over 75 different ferrous and non-ferrous air-melt alloys and use a master heat system to strictly control our alloys. Our alloys will meet all Federal, ASTM, Military and AMS specifications and we can provide secondary and support services to complete your investment casting project.

If you need assistance selecting a casting alloy, please contact us to discuss your unique investment casting requirements.

Stellite Cobalt-Base Alloys 

Stellite is a series of cobalt-chromium alloys that may also contain tungsten or molybdenum. They are non-magnetic, provide exceptional wear resistance and perform well in chemical and corrosive environments. These cobalt-base alloys also have an extremely high melting point, which makes them ideal for high temperature applications.

Additional benefits depending on grade include resistance to thermal cracking, surface fatigue and stress-rupture resistance. We offer precision investment casting using the following Stellite alloys:

  • Stellite #25
  • Stellite #31
  • Stellite #6
  • Stellite #21
  • Stellite #93

FSX-414 Cobalt-Base Alloy

FSX-414 is a cobalt-nickel alloy that provides high strength and corrosion resistance. It is typically used for investment casting high temperature components for aerospace, power plants and other applications.
