Nitinol is a shape memory alloy composed of nickel and titanium, with the name derived from its components.

It is known for its unique ability to return to its original shape after being deformed when heated above its transition temperature, which is typically between 70°C to 90°C.
The properties of Nitinol make it useful in a wide range of applications, from medical devices such as stents and orthodontic wires to aerospace engineering and robotics.

Its biocompatibility, corrosion resistance, and superelasticity make it a preferred material for many medical devices.
