quick question?Cobalt Based Castings

castingLooking for exceptional wear resistance, oxidation resistance up to 2,100 degrees (F), or high strength up to 1,500 degrees (F)? Chicago Vacuum Casting should be your source for Cobalt Based Castings.

Using the investment casting process, we produce castings in most grades of Cobalt alloys such as CB3 (good wear resistance), CB6 (best impact, oxidation resistant), CB21 (high strength), and CB93 (more economical with good wear resistance).

Because of the high cost of Cobalt alloys, Chicago Vacuum Casting produces cobalt based castings with minimum or no machining, holding typical tolerances of +/-.005” per inch. Don’t leave that expensive material on the floor in chips due to unnecessary machining.
