Cobalt Chrome Investment Casting: Properties, Specs & Uses
Cobalt chrome investment casting is the proven route for biocompatible, wear-resistant components used in implants, surgical tools, and hot-section parts. At Uni Tritech, India’s NADCAP-certified foundry, we cast CoCr alloys to net shape with full traceability.
This guide explains its properties, medical uses, and why surgeons rely on cast CoCr. See our investment casting process page and this cobalt-chrome reference.
What Is Cobalt Chrome Investment Casting?
Cobalt chrome investment casting uses the lost-wax process to form parts from cobalt-chromium alloys such as CoCrMo (ASTM F75). Because cobalt chrome is hard and biocompatible, the process is ideal for implants and wear-critical components.
This guide explains cobalt chrome investment casting: the materials, process, tolerances and quality controls that matter. Uni Tritech is India's Airbus-approved, NADCAP-certified foundry serving aerospace, defence and medical OEMs globally.
CoCrMo Medical Implant Casting
CoCrMo medical implant casting uses the F75 cobalt-chromium-molybdenum alloy designed for the human body. CoCrMo medical implant casting delivers the wear resistance, strength, and corrosion resistance that load-bearing implants demand over decades of service.
Why CoCrMo suits implants:
- Excellent biocompatibility for long-term body contact.
- High wear resistance for hip, knee, and joint surfaces.
- Strong corrosion resistance against body fluids.
- High strength and fatigue life under cyclic loads.
- Net-shape casting forms complex implant geometries.
Cobalt Alloy Surgical Casting Applications
Cobalt alloy surgical casting goes beyond implants. Cobalt alloy surgical casting produces forceps, clamps, blades, and dental frameworks that must stay sharp, sterilisable, and corrosion-free through repeated autoclaving.
- Surgical instruments: forceps, clamps, retractors, and blades.
- Dental frameworks and partial denture castings.
- Orthopedic hip, knee, and spinal implant components.
- Wear pads and bearings for medical devices.
Biomedical Cobalt Chromium Parts: Why CoCr Wins
Biomedical cobalt chromium parts outperform many alternatives on wear and corrosion. When biomedical cobalt chromium parts are investment cast and finished, they offer smooth bearing surfaces and consistent metallurgy for safety-critical use.
- Better wear resistance than stainless or titanium for bearings.
- Stable in the body with minimal ion release after polishing.
- Castable into thin, complex, near-net-shape geometries.
- Also used for cobalt superalloy turbine vanes at high heat.

Frequently Asked Questions
Yes. Cobalt chrome investment casting with the CoCrMo F75 alloy is widely used for hip, knee, and dental implants because it is biocompatible, wear resistant, and corrosion resistant in the body.
CoCrMo (ASTM F75) is the most common alloy for surgical implant castings, offering the wear resistance, strength, and biocompatibility load-bearing implants need.
It is used for orthopedic and dental implants, surgical instruments, medical device bearings, and cobalt superalloy turbine vanes that operate at high temperature.
Biomedical cobalt chromium parts are cast, then heat treated, machined, and polished to a smooth bearing surface, followed by passivation and full inspection.
Yes. Uni Tritech exports NADCAP-certified cobalt chrome investment casting to medical, aerospace, and industrial customers worldwide, with full traceability and documentation.
