Cobalt Alloys

Cobalt Alloys

Cobalt based alloys provide excellent corrosion resistance, are resistant to thermal fatigue have exceptional wear resistance, resist oxidation at elevated temperatures and have high strength up to 1500deg. F. Because of these properties, cobalt based alloys are commonly chosen for a variety of medical, aerospace, food processing and other investment casting applications. At ICAST we have the expertise in working with this super alloy that offers several performance benefits.

  • We work with various grades of Cobalt based alloys such as Cobalt 21, Stellite, Cobalt 25(L-605), and implantable grade ASTM F-75 CoCrMo to produce parts with complex geometries and tight dimensional tolerances.
  • When required, we conduct non-destructive testing on finished parts to ensure that the final components meet the NDT class and grade required.
  • We can cast near-net shape cobalt-based castings with minimal secondary machining required. Standard casting tolerances are +/- .005 inches per inch.


  • Medical implants
  • Food processing equipment (high wear)
  • Heavy industrial applications like plow tiles
  • Turbine Blades
  • Pump sleeves
  • Rotary rings
  • Blades





By working withI CAST for your next Cobalt casting, you get the following advantages:

  • Exceptional Quality: Exceptional visual appearance is possible for parts that require high visual quality.
  • Surface Finishes: 120 RMS or better is easily achieved
  • Close Tolerances: ±.005 inch per inch tolerance levels can be achieved
  • Near Net Shape Parts: Avoid long run time machine parts using near net cast parts.
