Request Medical Grade QuoteWhat is CoCrMo Alloy?
Cobalt-Chromium-Molybdenum (CoCrMo) is a high-performance biocompatible alloy offering exceptional wear resistance, corrosion resistance, and mechanical strength, making it the gold standard for orthopedic implants, dental prosthetics, and medical devices.
Biocompatible
Excellent biocompatibility with human tissue and body fluids, meeting ASTM F75 and ISO 5832-12 standards for surgical implants.
Wear Resistant
Superior wear resistance and low friction coefficient, ideal for articulating surfaces in joint replacements and load-bearing implants.
High Strength
Exceptional tensile strength up to 1200 MPa and yield strength exceeding 800 MPa for reliable long-term implant performance.

Frequently Asked Questions
What makes CoCrMo suitable for medical implants?
CoCrMo offers exceptional biocompatibility meeting ASTM F75 standards, superior wear resistance for articulating surfaces, excellent corrosion resistance in body fluids, high strength-to-weight ratio, and proven long-term clinical performance in orthopedic and dental applications.
How does CoCrMo compare to titanium for implants?
CoCrMo offers superior wear resistance and hardness compared to titanium, making it preferred for load-bearing articulating surfaces. Titanium has lower modulus closer to bone and better osseointegration. CoCrMo is ideal for hip/knee bearing surfaces while titanium excels for fixation components and bone integration.
Do you provide material certificates for medical applications?
Yes, we provide comprehensive documentation including material certificates with chemical composition analysis per ASTM F75/F1537, mechanical property test reports, heat lot traceability, biocompatibility certifications, and dimensional inspection reports meeting medical device manufacturing standards.
What machining processes are used for CoCrMo parts?
We employ precision CNC milling and turning with specialized tooling for CoCrMo’s hardness, investment casting for complex geometries, additive manufacturing (3D printing) for patient-specific implants, and finishing processes including polishing, passivation, and surface treatments to achieve required specifications.
Can you manufacture custom patient-specific implants?
Absolutely. We specialize in custom patient-specific implants manufactured from CT/MRI scan data using additive manufacturing and precision machining. Our capabilities include complex geometries, porous structures for bone ingrowth, and tight tolerances verified by CMM inspection for perfect anatomical fit.
What surface finishes are available for CoCrMo implants?
We offer various medical-grade finishes including highly polished surfaces (Ra < 0.05µm) for articulating components, bead-blasted or porous coated surfaces for bone ingrowth, passivation for enhanced corrosion resistance, and specialized coatings like hydroxyapatite or nitride layers for improved performance.
