Fil de Nitinol (fil Niti)
Nitinol Wire: Flexible, High-Strength Strands for Precision Medical Solutions
Nitinol Wire Description:
Fils de nitinol fins et solides, produits par étirage à froid, avec des diamètres allant de 0,025 mm (25 microns) à 3 mm. Le polissage de surface permet d'obtenir une surface lisse (Ra 0,1–0,4 µm).
Nitinol Wire Key Features:
- High tensile strength (up to 1100 MPa).
- Flexible with 15% elongation capacity.
- Shape memory adjustable between 10–40°C.
Nitinol Wire Certification and Standards:
ASTM F2063: Standard for medical nitinol properties.
ISO 10993: Biocompatibility testing for tissue contact.
ISO 15841: Applies to orthodontic wires; ISO 11070 for guidewires.
Manufacturer-specific tolerances (e.g., ±0,0003 inches) may apply.
Why Nitinol?
Nitinol’s blend of strength, flexibility, and biocompatibility—backed by rigorous standards—revolutionizes medical devices. Curious about specific uses or custom solutions? Contact us for more details!
Nitinol (NiTi), a nickel-titanium alloy, is renowned for its superelasticity and shape memory, making it a game-changer in medical applications. With a tensile strength of up to 1200 MPa and elastic modulus of 40–75 GPa, nitinol excels in demanding environments.
- Orthodontics: Braces wires (0,3–0,6 mm) apply gentle 1–3 N force for teeth alignment.
- Guidewires: Wires (0,89 mm, 150–260 cm long) navigate catheters through vessels.
- Surgical Staples: Formed into 3–10 mm staples, tightening at 37°C with up to 50 N force.
- Diameter: 0,025–3 mm
- Weight: ~0,05 g/m (at 1 mm Ø)
- Tensile Strength: 1100 MPa
- Bend Radius: Down to 5 mm
- Surface Finish: Ra 0,1–0,4 µm
