Muscle Wire - 0.012 Diameter (1 foot)
842 units available with a short lead time.
A one-foot (305 mm) length of 0.012" (0.30 mm) diameter Muscle Wire — a nickel-titanium shape memory alloy (Nitinol) that contracts when heated or when electrical current is applied. The wire transitions between a weaker, low-temperature martensitic form and a stronger, high-temperature austenite form.
In its martensitic state, the wire can be bent and formed into shapes. Applying approximately 1.5 A of current (or heating to ~100°C) causes it to revert to its memorised austenite shape with considerable force. The memory shape can be reset by annealing at ~500°C.
