NT0402 Nitinol Strip/Foil (Nickel Titanium)

Descriptions of Nitinol Strip/Foilnitinol-foil

Shape Memory Alloy (SMA) are one of the most promising smart materials available today, and they can provide the novel solution in several fields and for various applications (e.g. actuator, biomedical application, clamping systems, etc.). Shape Memory Alloys demonstrate a unique ability to recover their initial shape after deformation through a reversible thermo-elastic phase transformation.

Among the commercially available SMA, 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.

Advanced Refractory Metals (ARM) is a leading supplier of Nitinol products. All custom sizes and finished parts can be produced quickly to the highest industry standards.

Applications of Nitinol Strip/Foil

-Nitinol is used in cell-phone technology as a retractable antenna, or microphone boom, due to its highly flexible and mechanical memory nature.
-Nitinol is also used in some novelty products, such as self-bending spoons which can be used by amateur and stage magicians to demonstrate “psychic" powers or as a practical joke, as the spoon will bend itself when used to stir tea, coffee, or any other warm liquid.
-Demonstration model heat engines have been built which use nitinol wire to produce mechanical energy from hot and cold heat sources.
-Nitinol is highly biocompatible and has properties suitable for use in orthopaedic implants. Due to Nitinol’s unique properties it has seen a large demand for use in less invasive medical devices.

Packaging of Nitinol Strip/Foil

Our Nitinol Strips and Nitinol foils are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
