Cobalt-Chrome Bar (CoCr Bar)
Cobalt-Chrome Bar: Robust Solid Rods for Heavy-Duty Medical and Orthopedic Uses
Cobalt-Chrome Bar Description:
Solid cobalt-chrome rods, forged or extruded, with diameters from 4 mm to 60 mm and lengths up to 3 meters. L605 suits high-stress applications, while MP35N excels in corrosive environments.
Cobalt-Chrome Bar Key Features:
- Exceptional load-bearing capacity (up to 2000 N).
- Fatigue resistance (500 MPa over 10⁶ cycles for L605, 550 MPa for MP35N).
- High resistance to wear and pitting corrosion (MP35N shines here).
Cobalt-Chrome Bar Certification and Standards:
- ASTM F90 (L605): For CoCrWNi alloy bars.
- ASTM F562 (MP35N): For CoCrNiMo alloy bars.
- ISO 5832-12: CoCrMo for surgical implants.
- ISO 10993, FDA, and CE certifications; custom fatigue specs often included.
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.
- Orthopedic Rods: L605 bars (8–15 mm Ø, 100–500 mm long) support spinal fixation.
- Prosthetic Joints: MP35N rods (20–40 mm Ø) form hip and knee implant stems.
- Surgical Tools: L605 bars (4–10 mm Ø) craft durable instrument handles.
- Diameter: 4–60 mm
- Length: Up to 3 m
- Weight: 6,5 g/cm (at 10 mm Ø, L605), 6,6 g/cm (MP35N)
- Tensile Strength: 1000–1500 MPa (L605), 1200–1500 MPa (MP35N)
- Fatigue Strength: 500 MPa (L605), 550 MPa (MP35N) at 10⁶ cycles
