CoCrMo Powder
CoCrMo Powder Supplier and Exporter
CoCrMo powder (R31537 / R30075) is a vacuum induction melted, argon gas atomised cobalt-chromium alloy feedstock for additive manufacturing, supplied to ASTM F3213 (PBF) in 10-30 µm, 15-45 µm, 15-53 µm, 45-105 µm, 53-105 µm, 45-150 µm, 53-150 µm size fractions.
Combines biocompatibility with wear resistance no titanium alloy can match, which is why load-bearing articulating surfaces are made from it rather than Ti-6Al-4V.

What Properties Does Printed CoCrMo Reach?
Printed properties depend on the heat treatment, not just the alloy, so they are given per condition.
| Condition | Tensile strength | Yield strength | Elongation | Hardness |
|---|---|---|---|---|
| As built | 1100-1300 MPa | 800-1000 MPa | 10-20% | 35-45 HRC |
| HIP and solution annealed | 1000-1200 MPa | 700-850 MPa | 15-25% | 30-40 HRC |
HIP is standard for implant work: it closes internal porosity, which is what governs fatigue life in a load-bearing device.
Which Processes Can CoCrMo Powder Be Used In?
| LPBF | EBM | DED / cladding | MIM | Binder jetting | Thermal spray |
|---|---|---|---|---|---|
| Yes | Yes | Yes | Yes | Limited | Yes |
What Is CoCrMo Powder Used For?
Hip and knee implants, dental frameworks and crowns, and wear-resistant industrial components.
Post-processing
HIP and solution annealing; implant work adds surface finishing to the applicable ISO standard.
Characterisation and Packing
Each batch is supplied with chemical analysis, particle size distribution by laser diffraction to ASTM B822, apparent and tap density, and flow rate by Hall or Carney funnel. Morphology imaging, oxygen and nitrogen analysis and reporting to ISO/ASTM 52907 are available where your qualification requires them.
Powder is packed under argon in sealed containers with desiccant, labelled with lot number, alloy, particle size cut and date of atomisation.
