Nickel Titanium (also known as Nitinol) is the unique class of materials known as shape memory alloys,A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties.These properties include the shape memory effect,supere;asticity,and high damping capability.The properties of Nitinol can be modified to a great extent by changes in alloy composition,mechanical working,and heat treatment.In most cases a trial and error process is required to optimize these factors for a particular application.

Shape memory alloys (SMAs) are metals that "remember" their original shapes and can automatically recover from deformation at certain temperature (Phase Transition Temperature). They are useful for such things as actuators which change shape, stiffness, position, natural frequency and other mechanical characteristics in response to temperature or electromagnetic fields.

Ti-Ni alloy was the first and most useful of all shape-memory alloys. Its Phase Transition Temperature is very sensitive to the composition. (Each additional 0.1% Ni will causes the Phase Transition Temperature to drop 10 °C. Adding a third element will also significantly influence the Ti-Ni alloy's Phase Transition Temperature). In addition, the Ti-Ni alloy also has good heat and corrosion resistance, high strength, unique thermal and fatigue resistance, high biocompatibility and high damping characteristics, etc., which have won the material a wide range of application.

Applications: Ti-Ni shape-memory alloy wire can be used in cell phone antennas, children's toys, experimental materials, eye glasses components and medical equipment such as surgical stitching wire, birth control loop and high-quality memory alloy wire of other areas.
