USES AND APPLICATIONS

CoCr28Mo is a nonmagnetic Co, Cr and Mo content for implant. Good corrosion resistance and good fatigue and wear resistance. Compared to standard qualities, the percentage of Nickel is less than 0.1% to ensure better biocompatibility. This alloy is especially applicable for medical implants (endoprothesis and osteosynthesis), wherever high mechanical stress is expected. It is widely used in micromechanics, where hardness, toughness, ductility and corrosion resistance are required.
