MEMORY WIRE | Perfect for scientific demonstration

MEMORY WIRE

• This Memory wire is made of nitinol (nickel-titanium alloy)  exhibiting different properties from it’s parent metals by retaining a remarkable shape memory.
• It can be bent into almost any shape when cold and will remain in this shape until placed in hot water where it will resume it’s original shape.

(Wikipedia excerpt: ..."In metallurgy, a shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It is also known in other names such as memory metal, memory alloy, smart metal, smart alloy, and muscle wire.[citation needed] The "memorized geometry" can be modified by fixating the desired geometry and subjecting it to a thermal treatment, for example a wire can be taught to memorize the shape of a coil spring.

Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems. They can also be used to make hermetic joints in metal tubing, and it can also replace a sensor-actuator closed loop to control water temperature by governing hot and cold water flow ratio...")
