Matériels
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.
Application
- Bone Fixation: Plates (50–150 mm long) stabilize fractures with up to 500 N load capacity.
- Heart Valves: Frames (20–30 mm Ø) compress to 6–8 mm for delivery, then expand.
- Custom Implants: Cut into tailored shapes (e.g., septal defect patches).
Specifications
- Thickness: 0,1–2 mm
- Size: Up to 300 × 300 mm
- Weight: 32 g/100 cm² (at 0,5 mm)
- Tensile Strength: 1000–1100 MPa
- Cutting Precision: 0,01 mm
