Iron Chrome Cobalt

Iron Chrome Cobalt is a metal alloy of cobalt and chromium. Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants. This material is machinable and malleable and was originally designed as a replacement for Cunife. While it can still be used for this, the entire application must be known to match the properties needed. It requires a high degree of skill to make this material, and the manufacturer must be selected carefully.
