Explore SUNNING STEEL’s premium wrought cobalt-chromium-molybdenum (CoCr) alloy for implants. Ideal for surgery — metallic materials with high biocompatibility, strength, and corrosion resistance. ASTM F1537 / ISO 5832-12 compliant.
Cobalt-Chrome (CoCr) alloys, specifically wrought cobalt-chromium-molybdenum materials, are advanced metallic biomaterials engineered for use in orthopedic, spinal, and dental implants. Renowned for their exceptional biocompatibility, wear resistance, corrosion resistance, and high mechanical strength, CoCr alloys have become a gold standard for load-bearing implant components.
SUNNING STEEL supplies wrought Co-Cr-Mo alloys that meet the rigorous standards of the medical industry, conforming to specifications such as ASTM F1537, ISO 5832-12, and ISO 5832-4. Our CoCr products are suitable for machined, forged, and cast implant applications.
