Cobalt Chromium Molybdenum Metal Casting

Description Of Cobalt Chromium Molybdenum Metal Casting

Cobalt Chromium Molybdenum Metal Casting, also known as CoCrMo casting or cobalt chrome molybdenum casting, is a high-performance metal casting manufactured from cobalt-chromium-molybdenum alloys to ASTM F75 standard. CoCrMo alloys offer an exceptional combination of wear resistance, corrosion resistance, and biocompatibility, making them the material of choice for medical implants and demanding industrial applications.

ASTM F75 (UNS R30075) is a cast cobalt-chromium-molybdenum alloy containing approximately 28% chromium and 6% molybdenum. It offers excellent wear resistance, corrosion resistance, and biocompatibility, making it widely used for orthopedic implants such as hip and knee replacements, dental prosthetics, and cardiovascular devices.

Cobalt chromium molybdenum metal castings are produced using investment casting, which allows for complex geometries and near-net shapes. Custom sizes and shapes are available upon request. Surface finishes include as-cast, machined, ground, and polished. Typical applications include medical implants (hip and knee replacements, dental prosthetics), aerospace components, and industrial wear parts (valve seats, pump components).
