Нитиноловая проволока (нити-проволока)
Nitinol Wire: Flexible, High-Strength Strands for Precision Medical Solutions
Nitinol Wire Description:
Тонкие, сплошные нитиноловые нити, полученные методом холодного волочения, диаметром от 0,025 мм (25 мкм) до 3 мм. Полировка поверхности обеспечивает гладкость (Ra 0,1–0,4 мкм).
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.

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
