Product Intelligence In the world of load-bearing implants, there is no room for compromise. The material must survive the corrosive environment of the human body while enduring millions of load cycles. Layrr Materials CoCrMo is the gold standard for medical and dental additive manufacturing. Unlike stainless steels, our CoCrMo offers superior wear resistance and biocompatibility, free from nickel to prevent allergic sensitisation. We supply gas-atomised powder designed specifically to achieve the fine surface finish and mechanical density required for patient-specific devices. Material Behaviour & Microstructure The strength of CoCrMo lies in its ability to form a passive oxide layer while maintaining a rigid carbide structure. Self-Healing Passivation: A spontaneous Chromium-oxide (Cr2O3) film forms on the surface, rendering the material immune to physiological corrosion. Tribological Performance: The Molybdenum addition refines the grain structure and strengthens the solid solution, providing exceptional resistance to adhesive and abrasive wear—critical for articulating joints. High Specific Strength: Offers a stiffness-to-weight ratio that rivals Titanium, but with significantly higher hardness. Processing Advantage: The Layrr Standard Medical and dental printing demands absolute precision. A porous crown or a rough femoral stem is a rejected part. Our CoCrMo is characterised for: Nickel-Free Chemistry: Strictly controlled composition (Ni < 0.1%) to meet bio-safety standards. Fine Sphericity: Optimised for Laser Powder Bed Fusion (LPBF), enabling the printing of thin-walled dental copings and intricate trabecular structures for bone ingrowth. Thermal Stability: engineered to withstand the rapid heating and cooling cycles of laser melting without micro-cracking. Critical Applications While famous for its role in the operating room, CoCrMo's wear resistance also gives it a home in heavy industry: Orthopaedics: Knee and hip joint replacements, utilizing the alloy's wear resistance for articulating surfaces. Dental: Crowns, bridges, and removable partial denture (RPD) frameworks printed with high precision. Aerospace & Energy: Guide vanes and wind turbine components that require resistance to droplet erosion and high heat. Industrial Tooling: Injection moulds requiring a polished finish and high hardness.
