Product Description

Nickel-titanium alloy is a shape memory alloy. The memory alloy is a martensitic transformation alloy with a regular atomic arrangement and a volume of less than 0.5%. The strain can be as high as 20%. After the stress is removed, the original shape can be restored. The deformation that can still recover beyond the elastic limit is the superelastic energy. This alloy will deform under the action of external force. When the external force is removed, the original shape can be restored under certain temperature conditions. Because it has more than a million recovery functions, it is called "memory alloy". Nickel-titanium shape memory alloy is a special alloy that can automatically restore its plastic deformation to its original shape at a certain temperature.

SMAs have been used in a wide variety of applications spanning diverse industries. Apart from the flexible spectacle frames mentioned above, they can be used in bioengineering applications such as dental wires such as those used in dental braces, mending broken bones using metal plates, and for medical devices that help open clogged veins and arteries. They are used as wires and tubes in applications with hot fluids flowing through them. These materials are ideal as they can retain their shape even in a heated environment.
Another application of SMAs is in civil engineering. For example, they have been used in bridge structures. SMAs can dampen vibrations, hence tuning the natural frequency of various structures. This property of vibration damping has also been used in launch vehicles and jet engines. Newer lightweight alloys have also been discovered, such as magnesium-scandium that can have a variety of potential applications such as in aerospace applications and the medical industry for biodegradable self-expanding stents.
SMAs can also also used as actuators because of their ability to change shapes and have potential applications in aircraft and space vehicles because they are lighter and can help save energy compared to bulky mechanical actuators. Earlier this year, NASA demonstrated a nickel-titanium SMA actuator used in folding the outer portions of wings during flight. This change in the angle of the plane's wings according to wind and turbulence helps reduce energy use.
