Precision-Machined Small-Diameter Cobalt-Chromium Alloy Rods for Advanced Spinal Implants

Key Features of CoCr Alloy Bars for Spinal Implants

• High Strength & Fatigue Resistance – Ideal for dynamic stabilization and fusion systems.
• Biocompatibility – Excellent corrosion resistance and biocompatibility for long-term implantation.
• MRI Compatibility – Non-ferromagnetic, allowing for post-op imaging.
• Wear Resistance – Suitable for articulating components in motion-preserving devices.
• Precision Machining – Tight tolerances for spinal rods, connectors, and custom implants.

Common Applications in Spine Surgery

• Spinal Fusion Rods (posterior fixation systems)
• Dynamic Stabilization Systems
• Interbody Fusion Devices
• Pedicle Screw & Rod Constructs

Standards & Certifications

• ASTM F1537 (Wrought Cobalt-Chromium-Molybdenum Alloy)
• ISO 5832-4 / ISO 5832-12 (Implant-grade CoCr alloys)
