Your cart is empty.Nitinol Memeory Wire is a 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 Memory Wire. You can bend the 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 Memory Wire 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.

Excellent for an elementary school student who is interested in science!

It does what is says, but the wire is very small. I recommend finding another place to buy the same thing except longer, as this is very overpriced.

I purchased this item to do an experiment with my students at school. I didn’t find anywhere that the length of the actual useable wire was less than 3 inches!! That was a very expensive piece of wire. I could barely twist the wire into a shape for the experiment. It does work but I really feel I was ripped off on that purchase.

The first time I used a small plastic cup. I put the bent wire inside then poured hot water into the cup. It flew up and hit the sealing! I switched to a plastic bowl and my son poured the hot water in, as the hot water hit a part of the wire it fixed itself straight. Next, we twisted it into the shape of a spring and held it there with needle-nose pliers while heating it with a lighter. Then I put it into the bowl with ice and cold water for about 5 minutes, took it out, straightened it, put it back in the bowl and added hot water. It turned back into the spring! So much fun, next we are going to try to make it curl up without tipping over. The speed it changes is incredibly fast!

I had no idea it was only going to be 4" long. Very over priced for something so small

I use it for materials subject practicals. To show the behavior of nitinol wire.Its not easily available in open market.Recommended.

Nitinol alloy is really awesome. Since it contains nickel & hardest material titanium it is not easy to cut. This alloy reminds its original shape.Make the wire in desired shape and apply some heat, and then it will come back to original shape. Really awesome 😊
