Nitinol shape memory alloy Master Selector
This listing is for Shape Memory Alloy kind (the magic kind). Available in 15ºC, 30ºC, 40ºC, 60ºC, and 80ºC transition temps right on this listing, in 0.5mm, 1.0mm, and 2.0 mm diameters. Why not get one of each to experience the differences. Not all temperatures are available in all diameters. SHIPS UNCUT - the QUANTITY corresponds to the NUMBER OF FEET (31cm increments) you want of UNCUT wire!
It is activated by hot water and can be form-treated into any shape you can think of with a small torch lighter.

It comes pre-treated straight from the factory, so if you crumple up a chunk and throw it in a cup of hot water, it will jump out as straight as a ruler no matter what you did to it. You will not believe it until you see it.
2mm diameter is 16x thicker than the commonly sold .25mm. Avoid .25 as they are just too thin for any serious tricks or machines. 0.5mm and 1mm is also available. The thinner wires engage much quicker, but the thick wires are intense if dropped in hot liquid. Thinner is better for electrical actuation, and thicker works well with water or oil. See picture for comparison - this 2mm thickness is more suitable for paperclip shapes, etc, as it holds form much better, but it also requires more heat to react since it is thicker. Join multiple strands together to create monster power effects on demand.
If you order multiple quantities we will cut one long section off of the pictured roll so you can procure uncut sections and cut later as you please.
The wire has a lustrous titanium color (dark grey) with a bluish oxide tint on its surface. When freshly cut, the inner core is nickel white. Nitinol is very abrasion resistant and has self-healing properties, so the wire is quite hard to cut and kink. It does not require any special handling or protections from oxidation or moisture, and is non-toxic. The only way to damage it is by overheating it, so if you are using electricity instead of hot water to activate it be sure to use a current limiting circuit.
