Cobalt-Chrome Sheet: Versatile Flat Panels for Customizable Medical Implants
Cobalt-Chrome Sheet Description:
Panneaux plats en cobalt-chrome, laminés à chaud ou forgés, d'épaisseurs allant de 0,2 mm à 5 mm et de dimensions allant jusqu'à 400 × 400 mm. Le L605 assure la robustesse, tandis que le MP35N améliore la résistance à la corrosion pour les implants sur mesure.
Cobalt-Chrome Sheet Key Features:
- High hardness (350–500 HV for L605, 400–550 HV for MP35N).
- Corrosion resistance in physiological environments.
- Machinable into complex shapes with tight tolerances.
Cobalt-Chrome Sheet Certification and Standards:
- ASTM F90 (L605): For CoCrWNi alloys.
- ASTM F562 (MP35N): For CoCrNiMo alloys.
- ASTM F1537: General wrought CoCrMo standard.
- ISO 5840, ISO 13485, and ISO 10993: For cardiovascular, quality, and biocompatibility.
Why Cobalt-Chrome?
Cobalt-chrome’s strength, wear resistance, and biocompatibility—enhanced by grades like L605 and MP35N, and backed by rigorous standards—make it a top choice for medical innovations. Interested in specific applications or tailored solutions? Reach out to us for more information!
Cobalt-chrome (CoCr), an alloy of cobalt and chromium often enhanced with molybdenum, is prized for its exceptional strength, corrosion resistance, and biocompatibility. With tensile strength ranging from 800–1500 MPa and hardness of 300–550 HV, CoCr is a cornerstone in medical technology. Popular grades like L605 (Co-Cr-W-Ni) and MP35N (Co-Cr-Ni-Mo) elevate its performance.
- Bone Plates: L605 sheets (1–3 mm thick, 50–200 mm long) stabilize fractures under 600 N.
- Dental Frameworks: MP35N sheets (0,5–1 mm) form bridges and crowns.
- Valve Frames: L605 panels (0,3–0,8 mm thick) shape cardiac implants (20–35 mm Ø).
- Thickness: 0,2–5 mm
- Size: Up to 400 × 400 mm
- Weight: 41,5 g/100 cm² (at 0,5 mm, L605), 42 g/100 cm² (MP35N)
- Tensile Strength: 900–1300 MPa (L605), 1000–1400 MPa (MP35N)
- Hardness: 350–500 HV (L605), 400–550 HV (MP35N)
