Nitinol Shape Memory Muscle Wire 7 Varieties Sample Pack

Low-temperature activation, medium heat activation, and high heat activation wires in different diameters. Contents: 1 foot each of 0.5mm 70C, 1mm 80C, 1mm 40C, 1mm 15C, and 2mm 80C nitinol wire and 6" samples of 2mm 40C and 2mm 60C. This will give you a wide selection to experiment with to pick out what works best for your project as each wire exhibits different properties. Yes - it comes pre-trained STRAIGHT from the factory which is how you want it. You can re-train it if you want to take on a new shape. 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 feels very smooth and shiny to the touch. It does not require any special handling or protections from oxidation or moisture, and is non-toxic. Do not over heat it, as that will damage the property. If you are using electricity instead of hot water to activate it, be sure to use a current limiting circuit.

• 1 foot each: 1mm 15C (59F), 40C (104F), 80C (176F), and 0.5mm 70C (158F) wires
• 1 foot of super thick 2mm 80C and 6" sections of 2mm 40C and 60C sections to understand the difference
• Total of 7 different nitinol wires to find your favorite. Each wire exhibits different properties and activates at different temperatures - allowing to find the perfect alloy for your needs before purchasing larger amounts.
• Trained straight - works out of the box and can be re-programmed by performing a heat treatment
• Amazingly thick, strong, springy, stretchy, and smooth wires that are corrosion resistant and can have many uses in harsh environments even if not used for their shape memory feature.
