CoCrMo Cobalt-Chrome Powder
Cobalt-Chrome Powders · Metal Additive Manufacturing Powder
CoCrMo (ASTM F75) is the standard cobalt-chromium alloy for medical implants and dental restorations: hip and knee joints, crowns and bridges. It combines high wear resistance, corrosion resistance in body fluids and proven biocompatibility. LPBF as-built CoCrMo typically reaches 1,150 MPa UTS with 32% elongation; ISO 5832-4 compliant processing is the reference for implant manufacturers. Dental and medical buyers normally order 15-45 µm or 15-53 µm gas-atomized powder with tight carbon control (≤0.14% for medical grades) and full lot traceability. When comparing suppliers, ask for powder per ISO 5832-4 / ASTM F75 chemistry and documentation of clean-room-compatible packaging.

Frequently Asked Questions
How much does CoCrMo powder cost?
Medical-grade CoCrMo powder typically quotes $80-160 per kg. Verified suppliers on this page quote you directly, usually within 24 hours.
Is CoCrMo printed material certified for implants?
Yes — with powder per ISO 5832-4, validated LPBF processing and HIP where required, printed CoCrMo is cleared for hip, knee and dental devices under ISO 13485 quality systems.
What is the difference between CoCrMo and CoCrW for dental use?
CoCrMo (ASTM F75) is the implant-grade alloy with molybdenum; CoCrW adds tungsten for higher hardness and is favored for removable partial denture frameworks. Both are biocompatible.
Which particle size should dental labs order?
15-45 µm gives the surface quality needed for crowns and bridges on dental LPBF machines; 15-53 µm works on machines with 50+ µm layer settings.
What documentation do medical buyers need?
ISO 5832-4 chemistry certificate, particle-size distribution, oxygen analysis and lot traceability. Medical buyers should additionally request biocompatibility references from the powder producer.
