Product Description

Shape memory alloy (SMA) based on NiTi (53-57 wt.% Ni), Nitinol, when plastically deformed in the low-temperature martensitic phase, can be restored to its original shape or configuration by heating above a characteristic temperature.

Applications:
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.     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 be 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.
nother possible application of SMAs is in retrofitting buildings that are not designed considering seismic conditions. Here, the ability of SMAs to undergo large deformations with very little residual strain as well as their ability of reversible shape change with hysteresis is used. A beam column joint can be retrofitted with reinforced concrete using pre-stressed SMA wires. This significantly increases their shear strength and axial loading capacity, compared to wires that are stressed only when the concrete starts expanding.
Applications:
Anti-scalding protection: Temperature selection and control system for baths and showers. Memory metals can be designed to restrict water flow by reacting at different temperatures, which is important to prevent scalding. Memory metals will also let the water flow resume when it has cooled down to a certain temperature. 
Fire security and Protection systems: Lines that carry highly flammable and toxic fluids and gases must have a great amount of control to prevent catastrophic events. Systems can be programmed with memory metals to immediately shut down in the presence of increased heat. This can greatly decrease devastating problems in industries that involve petrochemicals, semiconductors, pharmaceuticals, and large oil and gas boilers. 
Tubes, Wires, and Ribbons: For many applications that deal with a heated fluid flowing through tubes, or wire and ribbon applications where it is crucial for the alloys to maintain their shape in the midst of a heated environment, memory metals are ideal.
Eyeglass Frames: In certain commercials, eyeglass companies demonstrate eyeglass frames that can be bent back and forth, and retain their shape. These frames are made from memory metals as well, and demonstrate super-elasticity.
