Nitinol belongs to a class of materials called Shape Memory Alloys (SMA). SMA's have interesting mechanical properties. Flexinol which is a trade name for Nitinol actuator wire, has been trained to contract when heated, which is the opposite of what standard metals do when heated which is expand. Not only does this alloy contract, but does so with a 100 times greater thermal movement (expansion-contraction) than standard metals.
Another interesting property of SMA's is called the Shaped Memory Effect (SME). The alloy can be made to remember a particular shape. Once a shape has been remembered, the alloy may be bent out of shape. Then returned to its original shape by heating the alloy about it transition temperature. This SME property is used in a toy called Nitinol Memory Wire.
You can bend the Nitinol Memory Wire toy into any shape you want, then place it in hot water and the wire quickly whips itself back into shape. It is interesting to watch this wire almost magically unfold and uncoil itself back into its original shape. The Nitinol Memory toy is made of nitinol wire with a low transition temperature (the temperature of hot water). The force generated when the wire is reverting is surprisingly strong. One square inch of Nitinol material generates a shape returning force of + 30,000 PSI.
Nitinol wire is the most mature form of this unique superelastic and shape memory alloy, being commercialized in the mid 1980's. It is available in many different sizes, alloys and finishes. And, shape memory or superelastic forms are both offered. Niti shape memory alloys are gaining increasing use in the medical device industry for Nitinol catheter stents, guidewires and other critical applications.
What is Shape Memory? Shape memory is a property of select materials that have the ability to "remember" the shape given during original thermo-mechanical processing allowing the material to revert to that original shape when subjected to heat. Materials with shape memory properties allow for the creation of lightweight solid-state devices that would otherwise require the use of mechanical systems.
Shape memory alloy is commonly known as, and marketed under, the following names: SMA smart metal memory metal memory alloy muscle wire smart alloy
Nickel titanium, or Nitinol, properties include the shape memory effect, superelasticity, and high damping capability. By changing composition, mechanical working, and applying heat treatment these technical properties of NiTi shape memory alloys can be modified to a great extent to suit the specific application
Shape Memory Alloy Applications Possible applications of shape memory and super-elastic alloys include: Catheter shafts Stents Valve frames Needles Orthodontic guidewires Endoscopic guide tubes Occluders Retrievers Distal protection Laproscopes
