Nitinol Spring Description
Size: Customized
Material: Titanium Nickel Alloy
Density: ~6.45 g/cm3
Surface: Black or Pickled or Polished
Nitinol spring is a type of shape memory spring. Shape Memory Alloys (SMA) are one of the most promising smart materials available today, and they can provide novel solution in several fields and for various applications (e.g. actuator, biomedical application, clamping systems, etc.). Shape memory nitinol demonstrates a unique ability to recover their initial shape after deformation through a reversible thermo-elastic phase transformation. This ability allows shape memory nitinol to recover from large strains, either spontaneously (pseudo elasticity) or through an increase in temperature (Shape Memory Effect). Among the commercially available Shape Memory Alloys, nickel-titanium (Ni-Ti and Ni–Ti-based) alloys are outstanding due to their excellent performance, reliability, and strain recovery properties. Ni-Ti alloy is attractive for various medical applications due to its biocompatibility, corrosion resistance, and fatigue behavior.

Nitinol Spring Specific Advantages
- Superior reliability.
- No gas or liquid leaks.
- 2-3x higher heat sensitivity compared to waxy components.
- Shorter response time to temperature changes.
- Lowered the total cost of modern SMA springs.
- Our Nitinol can be used in standard compression, extension, or torsion springs.
Application
Commercial applications include:
- Dentistry – bracing wires and brackets
- Medicine – vein stents
- Optics – frames for eye glasses
- Heat switches
- Fire safety devices
We supply Nitinol spring (nickel-titanium alloy)of good quality. We also supply one-way and two-way shape memory and superelastic Nitinol Springs.
Two way-Shape Memory
Nitinol spring that restore high-temperature phase shape when heated, and restore cooling temperature phase shape when cooled.
One way-Shape Memory
Nitinol spring deform at lower temperature, restore the shape before deformation when heated. It only shows shape memory phenomenon when heating.
