Nitinol wire is a metal alloy wire made primarily of Nickel and Titanium (roughly 50/50). Its name comes from its composition (Nickel Titanium Naval Ordnance Laboratory, where it was discovered).
It is famous for two unique properties not found in standard metal wires:
Nitinol can "remember" and return to a pre-programmed shape when heated.
How it works: You can bend a cold Nitinol wire into any shape. When you heat it past a specific temperature (e.g., with hot water or an electric current), it will instantly snap back to its original, straight or pre-set form.
Example: A bent Nitinol wire straightens out in warm water.
At room temperature (above its transformation temperature), Nitinol is extremely flexible and can withstand massive deformation without taking a permanent set.
How it works: You can bend or twist a Nitinol wire up to 10-30 times more than stainless steel, and it will spring back to its original shape instantly when released. This is like "memory foam" for metal.
Example: Flexible eyeglass frames that can be twisted without breaking.
