Applications
There are four commonly used types of applications for nitinol.
Free Recovery: nitinol is deformed at a low temperature, and heated to recover its original shape.
Constrained Recovery: The same, except that recovery is rigidly prevented, and thus a stress is generated.
Work Production: Here the alloy is allowed to recover, but to do so it must act against a force (thus doing work).
Superelasticity: As discussed above, here the nitinol acts as a super spring.
In 1989 a survey was conducted in the United States and Canada that involved seven organizations. The survey focused on predicting the future technology, market, and applications of SMA's. The companies predicted the following uses of nitinol in a decreasing order of importance: (1) Couplings, (2) Biomedical and medical, (3) Toys, demonstration, novelty items, (4) Actuators, (5) Heat Engines, (6) Sensors, (7) Cryogenically activated die and bubble memory sockets, and finally (8) lifting devices.[17]
Nitinol is also popular in extremely resilient glasses frames. It is also used in some mechanical watch springs.
It can be used as a temperature control system; as it changes shape, it can activate a switch or a variable resistor to control the temperature.
It is used in cell-phone technology as a retractable antenna, or microphone boom, due to its highly flexible and mechanical memory nature.
It is 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.
It can also be used as wires which are used to locate and mark breast tumours so that following surgery can be more exact.
Due to the fact it can change shapes it is also used as a golf club insert.
Nickel titanium can be used to make the underwires for underwire bras.
