Cobaltchromium, often abbreviated as CoCr, refers to an alloy primarily composed of cobalt and chromium. These alloys are known for their exceptional strength, hardness, corrosion resistance, and biocompatibility. The specific properties of a CoCr alloy can be tailored by varying the proportions of cobalt and chromium, as well as by adding other elements like molybdenum, nickel, iron, and tungsten.

The high chromium content is responsible for the alloy's excellent resistance to oxidation and corrosion, even in harsh environments. Cobalt contributes significantly to the alloy's hardness, wear resistance, and high-temperature strength. Molybdenum is often added to further enhance strength and corrosion resistance.

Due to its unique combination of properties, cobaltchromium alloys find extensive use in demanding applications. A prominent area is in the medical field, where they are widely utilized for orthopedic implants, such as hip and knee replacements, due to their biocompatibility and ability to withstand the stresses of the human body. They are also used in dental prosthetics and surgical instruments.

Beyond medical applications, cobaltchromium alloys are employed in the aerospace industry for components exposed to high temperatures and corrosive conditions, like turbine blades. Their wear resistance makes them suitable for tooling, engine parts, and industrial machinery operating under abrasive conditions. The development of various CoCr alloy compositions continues to expand their utility in advanced engineering and biomedical fields.
