Description
Nitinol Wire Applications
Thanks to its unique combination of superelasticity and shape memory, Nitinol offers outstanding performance in demanding environments. In addition, its excellent resistance to corrosion and long fatigue life make it a preferred material across advanced medical technologies.
As a result, Nitinol Wire Applications cover a wide range of precision medical uses, such as:
- Vascular and peripheral stent systems
- Minimally invasive catheter components
- Precision endodontic instruments
- High-performance mandrels and cores
- Retrieval and extraction baskets
- Advanced surgical tools
- Flexible snares
- High-precision guidewires
Moreover, Nitinol wire is increasingly used in robotic-assisted surgery and micro-invasive devices, where flexibility and durability are critical.
Nitinol Wire Surface Finishes
To meet different performance and aesthetic requirements, we offer a variety of surface finishes. Each option supports specific Nitinol Wire Applications by enhancing corrosion resistance, friction performance, or visual identification.
- Light oxide finish– Smooth surface with a light appearance, ideal for general medical use
- Dark oxide finish– Enhanced durability with a darker protective layer
- Amber oxide finish– Distinctive color for identification and specialized applications
- Oxide-free etched surface– Clean and bright, suitable for precision devices
- Chemical pickling– Improved surface purity and consistency
- Polished oxide-free finish– Ultra-smooth surface for reduced friction applications
