Cobalt-Chrome Wires (CoCr Wires)
Cobalt-Chrome Wire: Flexible, High-Strength Strands for Precision Medical Solutions
Cobalt Chrome Wires Description:
Solid cobalt-chrome strands produced via cold drawing, with diameters from 0,02 mm (20 microns) to 4 mm. Polished to Ra 0,1–0,5 µm, L605 and MP35N wires offer tailored properties—L605 for toughness, MP35N for corrosion resistance.
Cobalt Chrome Wires Key Features:
- Superior wear resistance for prolonged use (L605 excels here).
- High tensile strength (MP35N reaches up to 1400 MPa).
- Excellent biocompatibility with blood and tissue.
Cobalt Chrome Wires Certification and Standards:
- ASTM F90 (L605): For CoCrWNi wire in medical applications.
- ASTM F562 (MP35N): For CoCrNiMo wire.
- ISO 10993: Biocompatibility testing.
- ISO 15841 (orthodontics) and ISO 11070 (guidewires); manufacturer tolerances apply.
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
- Orthodontic Wires: L605 wires (0,3–0,8 mm Ø) deliver 2–5 N force for teeth alignment.
- Guidewires: MP35N wires (0,5–1 mm Ø, 100–300 cm long) navigate vascular systems.
- Surgical Sutures: Thin MP35N wires (0,1–0,5 mm Ø) secure tissues with up to 60 N strength.
- Diameter: 0,02–4 mm
- Weight: ~0,065 g/m (at 1 mm Ø, L605), ~0,066 g/m (MP35N)
