People sometimes get the wrong one (the more common "fishing line" type which resists changing its shape (kink-free wire)). This shape memory type can be worked into any shape imaginable, and immediately jumps into its predefined memory shape when heated to 70º C (hot water). Unlike the body-temp variants, this alloy is more suitable for robotics, machines, etc as it transitions more predictably above ambient temperatures.
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.
Currently only available in 0.5mm diameter, which is twice as fat as the commonly sold .25mm. Avoid .25 as they are just too thin for any serious tricks or machines. This thickness is perfect for joining 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.
