Nitinol Strip(Nitinol Flat Wire) for Sale: Superelastic Excellence for Advanced Designs

Get top‑quality Nitinol Strip right here. We manufacture and supply premium Nickel‑Titanium strips designed for the most challenging medical, aerospace, and precision engineering projects. Thanks to its remarkable superelasticity, Nitinol delivers performance you can rely on when every detail counts.

What is Superelastic Nitinol?

Nitinol is a unique metal alloy composed of  (Ni) and  (Ti). Unlike ordinary metals, it can bend, twist, and flex far beyond the limits of steel or titanium alloys — then spring back to its original shape. This occurs because Nitinol’s internal structure can transform easily under stress.

Moreover, this superelastic behavior works best at or near room temperature, making it ideal for countless applications. Nitinol can also “remember” a specific shape when activated by heat (shape memory), although superelasticity is its standout feature when used in strips.

Nitinol Strip （Nitinol Flat Wire）Grades We Offer

Medical Grade

Ideal for implants, guidewires, stents, and other precision medical devices. Importantly, our medical‑grade strips adhere to ASTM F2063 specifications, ensuring exceptional purity, biocompatibility, and dependable long‑term performance.

Commercial Grade

Perfect for a broad range of engineering and consumer applications, commercial‑grade strips deliver outstanding superelasticity, fatigue resistance, and corrosion protection.

Dimensions & Forms

We supply Nitinol strips in a variety of thicknesses and widths — from ultra‑thin (0.05 mm / 0.002”) to several millimeters thick. Additionally, we offer precision surface finishes, including:

• Polished Finish — Reduces friction and improves surface quality

• Etched Finish — Enhances bonding, coating, or adhesive performance

Most importantly, every strip is manufactured to tight tolerances, ensuring consistency and precision for every application.

Key Applications for Nitinol Strip

Medical Devices

From guidewires that navigate the body to stents supporting arteries, Nitinol strips enable breakthroughs across minimally invasive medical technologies. Moreover, their fatigue resistance and superelasticity are vital for orthopedic archwires and other precision medical tools.

Industrial and Aerospace Solutions

Nitinol strips enable smart actuators, vibration‑damping structures, and robust sensors that operate reliably in harsh environments. In aerospace and defense, these strips are used for deployment mechanisms and adaptive structures that tolerate repeated cycling.

Consumer Products

Their unique properties have found a place in everyday life — making eyewear more durable, sports equipment more resilient, and electronics more reliable.

Research & Development

In addition, researchers and engineers use Nitinol strips for robotics, energy harvesting, and advanced experimental applications that require precise, fatigue‑resistant materials.

Why Choose Nitinol Over Other Metals?

• ✅ Extreme Flexibility: Nitinol can bend and recover far beyond the limits of steel or titanium.

• ✅ Excellent Fatigue Life: Enables millions of bending cycles without cracking or deformation.

• ✅ Consistent Force: Provides stable spring‑like behavior across long displacement ranges.

• ✅ Biocompatibility: Medical‑grade strips are safe for long‑term implantation.

• ✅ Shape Memory Effect: Enables thermal activation and precision motion when needed.

Compared to Other Alloys:

• Stainless Steel: Strong but prone to permanent deformation and fatigue over time.

• Titanium Alloys: Strong and light but lack the superelasticity and recovery of Nitinol.

• Copper Alloys: Good for conductivity but weaker and unable to match Nitinol’s resilience.

• Aluminum Alloys: Light and soft, but unsuitable for high‑fatigue or precision applications.
