CoCrMo Alloy (ASTM F1537, Wrought)

Verifiedmetal
UNS R31537· Wrought CoCr· CoCrMo Forged

CoCrMo is a wrought cobalt-chromium-molybdenum alloy (ASTM F1537) designed for high-strength, corrosion-resistant applications requiring excellent biocompatibility and fatigue durability. It is the workhorse material for load-bearing orthopedic implants—hip and knee replacements, spinal fusion devices—and cardiac applications like stents and heart valve components, where it must withstand years of cyclic loading in the corrosive physiological environment. Engineers select this alloy over titanium or stainless steel alternatives when implants must tolerate high contact stresses, when manufacturing via wrought processing (forging, rolling) is economical, and when the material's proven long-term clinical track record is essential for regulatory approval.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
