Description
Superelastic Nitinol Wire Designed for Medical Device Applications
Medical wire manufacturers: Discover the precision and reliability your next‑generation medical devices demand. Our high‑quality Superelastic Nitinol Wire, enhanced with a Black Oxide finish, provides outstanding reliability and precision for medical applications.With precisely 55% Nickel content, this medical‑grade material meets the highest standards for quality, biocompatibility, and long‑term reliability.
Material: The Power of Superelastic Nitinol
✅ Nitinol, a precision Nickel‑Titanium alloy, offers unique superelastic and shape‑memory properties that set it apart from any other material.Its ability to deform and return to its original shape reliably, millions of times, is why it’s the go‑to choice for critical medical applications. Our medical‑grade Superelastic Nitinol Wire is manufactured to the highest standards (ASTM F2063), ensuring precise composition and performance for patient safety and device reliability.
Custom Diameters for Every Medical Need
✅ We recognize that each medical device comes with its own specific design and performance demands.Our Superelastic Nitinol Wire is available in a wide range of diameters — from 0.05 mm (0.002”) fine gauges to thicker sizes exceeding 2.0 mm (0.08”). Need a custom diameter? Our technical team can collaborate with you to design and produce the exact specifications required for your device.
Medical Applications for Superelastic Nitinol Wire
This Black Oxidized Superelastic Nitinol Wire excels in a variety of challenging medical environments:
-
✅Guidewires & Micro‑Guidewires: The black oxide surface improves fluoroscopic visibility, while its superelasticity delivers superior trackability and kink resistance.
-
✅Catheter Hyb Components: use precise braiding, main wire support, and torque responsiveness.
-
✅ Orthodontic Archwires: Deliver smooth, consistent pressure for comfortable and effective tooth alignment.
✅ Stent Systems: Serve as vital mandrels and core wires, ensuring accurate placement and reliable expansion. -
✅Endoscopic Instruments: Ensures flexible, durable, and resilient performance.
-
✅Minimally Invasive Tools: Enables precision, shape memory actuation, and long‑term durability.
-
✅Orthopedic Devices: Supports fatigue‑resistant cables and fixation hardware.
-
✅Dental Implants: Provides resilient, biocompatible performance.
-
✅Neurovascular Devices: Enables precision coils, stents, and delivery platforms.
-
✅Filter Systems: Supports precision frames with long‑term reliability.
The Advantages of a Black Oxide Finish
The special surface treatment of our Superelastic Nitinol Wire delivers benefits that extend beyond its superelastic and shape memory characteristics:
-
Enhanced Radiopacity: Improves visibility under X‑ray and fluoroscopy.
-
Reduced Glare: Enables clearer device tracking and positioning.
-
Improved Lubricity: Enables smoother navigation through catheters and vessels.
-
Better Biocompatibility: Provides a stable surface for long‑term implantation.
Why Nitinol Must Be Produced Professionally
Warning: Nitinol can’t be cut, shaped, or formed at home. Its advanced properties require precision equipment and highly controlled environments:
-
Melting/Casting: Requires temperatures >1300 °C (2372 °F), vacuum or inert gas environments, and state‑of‑the‑art equipment.
-
Forming: Involves precise thermal treatments and rapid quenching that are impossible to replicate in a home workshop.
-
Cutting: Must be done with specialized equipment (EDM, laser cutting) and cooled properly to preserve superelastic and shape memory characteristics.
Trying to work Nitinol with basic tools will ruin its properties and can be dangerous. Always source from trusted medical‑grade suppliers.
