2 Pcs 5 Feet Shape Memory Nitinol Wire 1.0 mm 40° C (18ga 104 °F) Pre Trained Wire Nitinol Shape Memory Alloy for Research Labs Classroom Display

What waste of my money and time.

This worked great for building a diy antenna, it's a bit difficult to work with so make sure you have a decent cutter and a good way to crimp into place.

The pieces I recieved are like tempered steel. Very springy and difficult to bend. However, when bent within the requisite temperature range they do NOT return to the original shape when heated or cooled, as real nitenol should.

Great NiTi wire! I like that it loses its strength when exposed to temperatures below 0 degrees Centigrade to -40℃, and it's like a solder wire when it's already at -4 to -7℃. The wire is high grade, light, and has a dark shiny, pewter-like color with a high superstrength sprig-like feature. What a bargain!

The wire comes "pre-trained" i.e. straight and cannot be manipulated or bent as the video suggests or other nitinol wires do. You can heat it up and retrain it into a different shape and it will hold that shape but again, if you try to bend it in this new shape it will simply bounce back once you let go. It's too thick and strong to be used as an experiment demo.

I got this demo of some "space age" materials in STEM class. 2X the samples you can buy of US-made materials. Remarkablely springy material. It was fun to experiment with this exotic wire.

Perfect for my project. Making antennas.

This does not work. I am familiar with nitinol wire and this does not work. Junk.
