Cobalt Chrome Guide Why it is used for Implants Jewelry
About Cobalt-chrome (CoCr) Cobalt-chrome (CoCr) as its name suggests in general consists of chrome cobalt and other metals (molybdenum nickel etc.). It is a metal alloy that has outstanding strength as well as wear and corrosion resistance. Because of these features and it s biocompatibility cobalt-chrome is often used for making dental/orthopedic implants and rings.
