Nitinol Wire
Our nitinol wire and strip offer exceptional precision and versatility, engineered to meet the demands of the most complex designs requiring intricate geometries. By carefully controlling chemical composition and thermal processing, we deliver materials with outstanding durability, flexibility, and kink resistance, making them indispensable for a wide range of medical device applications.
This production begins with the highest quality ingot, which is first drawn into coil and then carefully reduced to the desired wire diameters through a controlled drawing process.
Nitinol Wire Applications
Nitinol’s mechanical properties include excellent corrosion resistance, fatigue performance, and exceptional elasticity. These characteristics make our nitinol wire suitable for many medical device applications, including:
- Stents
- Catheters
- Endodontic files
- Mandrels
- Baskets
- Surgical instruments
- Snares
- Guidewires
Nitinol Wire Finishes
- Soft oxide (light)
- Hard oxide (dark)
- Amber oxide
- Etched (oxide-free)
- Pickled
- Etched and mechanically polished (oxide-free polished)
