Cobalt alloys

CoCr (Stellites), CoCrMo, CoCrNi

Co28Cr6Mo

This class of alloy is characterised by having excellent mechanical properties (strength, hardness etc.), corrosion and temperature resistance. Such alloys are commonly used in biomedical applications such as dental and medical implants and also for high-temperature engineering applications such as in aero engines.  CoCrMo alloys are the materials of choice for applications such as knee implants, metal-to-metal hip joints and dental prosthetics. Cobalt alloys also play an important role in the performance of aero- and land-based gas turbines. While vacuum cast nickel alloys predominate in the hot sections of modern aero turbine engines, cobalt alloys are routinely specified for particularly demanding applications such as fuel nozzles and vanes for industrial gas turbines.

It’s composition corresponds to AMS F75, UNS R31538.
