    Worked great as a science experiment with the kids. Reacts really fast in just warm water. ...so fast you its just a blur as it snaps straight.

    If you bend it too severely, it will just break off.

    Je connais le Nitinol, mais jattendais de cet achat une notice explicative pour savoir comment pré-contraindre une forme. Là, rien ! Un sachet plastique, avec le fil à lintérieur et dem..dez vous. Aucune info sur les températures de contrainte et celle de retour à la forme contrainte. Très déçu.

5 feet (1.5 meters) of 1mm diameter Nitinol SMA (shape memory alloy) wire. One of our favorites due to a comfortable warm, not-too-hot transition phase. This wire will become rigid and return to straight when exposed to temperatures above 40 C (hot water, lighter, heat gun, etc). Yes - it comes pre-trained STRAIGHT from the factory which is how you want it. You can re-train it if you want by heating it (500 C for 45 minutes) in the new desired shape. The wire has a lustrous titanium color (dark grey) with a bluish oxide tint on its surface. When freshly cut, the inner core is nickel white. Nitinol is very abrasion resistant and has self-healing properties, so the wire is quite hard to cut and kink. It feels very smooth and shiny to the touch. It does not require any special handling or protections from oxidation or moisture, and is non-toxic. Do not over heat it, as that will damage the property. If you are using electricity instead of hot water to activate it be sure to use a current limiting circuit.
