Nitinol foil, 0.05mm (0.002in) thick, superelastic, flat annealed, pickled surface

Nitinol foil is used in cell-phone technology as a retractable antenna, or microphone boom, due to its highly flexible and mechanical memory nature. It is also 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 is highly biocompatible and has properties suitable for use in orthopaedic implants. Due to Nitinol's unique properties it has seen a large demand for use in less invasive medical devices.
