The shape memory effect comes from the mixture of nickel and titanium transferring between the martensite and austenite phases of crystal structure. Basically, what this looks like is you have a wire that you can straighten, bend into any shape, mash, etc. and then place it in hot water to watch it come back to its original shape. The uses for this are endless. These make wonderful magic tricks for when you dunk the wire into someone's coffee, the wire turns into the card that they have in their hand. They're great for birthday parties to see your child's amazement when this simple piece of wire turns into their name when someone 'accidentally' spills coffee on it. Other uses include robotics, heat engines, science projects, practical jokes, artery stents for a bypass surgery, the only limitation is your creativity.

For line, the transition temperature varies considerable across the length of the wire. About half can’t be bent at all!

Good thickness, do not try cutting into smaller pieces unless you have something that will cut through titanium wire. I received the product exactly as described

but it's not perfect. Training it at 500 deg Celsius is not easy. A 1mm diameter nitinol wire has a minimum curve radius of about 3/8 inch, so it has limited shaping capability

This product can quickly and worked perfectly for my application. Strong and easy enough to bend into shapes with a propane torch, and quickly returns to original shape with some slight heating.

My college-aged daughter loved this birthday present. It worked just as expected: bend it willy nilly, then place it in warm water, and bam, the wire straightens. There is more she can do with it, but she's really pleased with it so far.
