Durable medical and dental prosthetics
Cobalt-Chrome alloys are standard alloys in the medical and dental fields. Due to the high hardness, Cobalt-Chrome alloys are used to produce dental prostheses. This is also influenced by the biocompatibility of the alloy. Being a tough material, Cobalt-Chrome alloy is usually cast and not machined. Other uses for Cobalt-Chrome are prosthesis and knee or and hip joint implants.
