Nitinol Metal Strip – Superior Flexibility and Fatigue Resistance

Premium Nickel-Titanium Material

Do you want to Learn more about our Nitinol Wire products and their applications?

Our nitinol metal strip is manufactured using a high-purity nickel-titanium alloy, generally containing 50.9% to 56% nickel and 49.1% to 44% titanium. This intelligent metal delivers outstanding superelasticity and shape memory behavior.Through carefully controlled melting and precision processing, we ensure the nitinol metal strip maintains consistent quality and reliable mechanical performance. Each production step is rigorously monitored to meet the most demanding specifications.

Superelastic Grades: SE508 & SE508N

SE508 and SE508N are the two high-performance grades of superelastic nitinol available from our portfolio.

• Ideal for common superelastic tasks, SE508 delivers outstanding flexibility and excellent return-to-shape performance.

• SE508N offers improved fatigue resistance, making it perfect for components under repeated strain.

Both grades function optimally at body temperature, making them highly suitable for medical applications. We tailor the transformation temperature (Af) through heat treatment, giving you repeatable and predictable superelastic behavior.

Dimensional Range

Select from a wide range of sizes to suit your specific application:

• Thickness: 0.10 mm to 3.0 mm (0.004″ to 0.118″)

• Width: 1.0 mm to 100 mm (0.04″ to 4.0″)

• Standard Lengths: 100-2000 mm (Custom lengths on request)

Each nitinol metal strip is precision-rolled and cut to tight tolerances, whether for micro-scale devices or large structural applications.

Versatile Applications of Nitinol Metal Strip

Engineers and designers across industries rely on nitinol strips for their flexibility and durability:

• Medical Devices: Orthodontic archwires, catheter reinforcement, guidewires, surgical staples

• Industrial Systems: Actuators, connectors, sensors, fluidic control elements

• Consumer Electronics: Flexible phone antennas, eyeglass frames, smart wearables

• Aerospace Components: Deployable mechanisms, vibration control elements

• Robotics: Adaptive grippers, flexible joints, precision motion parts

The superelasticity of nitinol metal enables extreme deformation with full recovery, making compact and robust designs possible.
