CoCrMo
CoCrMo refers to a cobalt-chromium-molybdenum alloy used widely in medical devices and dental restorations. The alloy is valued for its high strength, hardness, wear resistance, and corrosion resistance, particularly in applications where articulating surfaces are exposed to body fluids and mechanical loading.
Commercially, CoCrMo alloys for implants consist mainly of cobalt with chromium about 25–30% and molybdenum 5–10%.
Mechanically, CoCrMo exhibits high yield and tensile strengths and hardness, with an elastic modulus around 210–230
Manufacturing uses casting and wrought processing; modern implants often use powder metallurgy with HIP, followed by
Uses include orthopedic implants such as hip heads, liners, and knee components, where the material interfaces
Overall, CoCrMo remains a standard material in load-bearing implants, balancing mechanical performance and biocompatibility, with ongoing
