Description

Nitinol Memory Wire instantly returns to its “trained” state

Nitinol Memory Wire demonstrates properties that seem almost magical! It is possible to change its shape and then have it “spring back” to its original shape by adding energy. Includes 1-foot of memory wire.

Nitinol (pronounced “night-in-all”) is an alloy metal; its name stands for Nickel (Ni), Titanium (Ti), and the Naval Ordnance Laboratory (NOL) where it was discovered. Bend it, then drop it into hot water and watch it return to its original shape!

This crystalline metal changes phase around 75°C. You can also retrain this wire by annealing it. First, bend it into the desired shape, heat it to a dull red glow along the entire length, and then cool it by immersing it in water. After cooling, the wire can be deformed but will instantly return to its newly trained shape when dunked into hot water!

It is also possible to permanently change the shape of “memory” and then stress by bending it, but recover the new shape again. There are many possibilities to stress and test this alloy.
