Outstanding

Main highlights

•Nitinol isn't just wire – its unique shape memory means it snaps back to its original shape when heated to 40°C (104°F). Just add a bit of hot water, and watch it spring to life.
•Our wires are designed to activate at a temperature (104F) that won’t burn your fingers, making it perfect for science classes, engineering demos, and curious tinkerers alike.
•Featuring a smooth low-friciton black oxide coating, this nitinol wire looks as great as it performs.
•Our wires are pre-trained into a straight line, ensuring they're ready to use right out of the box — no additional training or heat treatment required.
•At room temperature, our nitinol wire is ultra-flexible, allowing you to bend it into a new shape before activating it.

Outstanding

Main highlights

•Trained straight - the wire is very soft and pliable at room temperatures, and becomes stiff and straightens out at a very low heat point of 40C (about 100F), making it suitable for demonstrations without getting burned.
•1.0 mm (0.04") diameter is very thick, this wire can hold or pull many pounds of weight and it is virtually unbreakable.
•Wire can be trained to take on a different shape by heat treating it at 500C and quenching in water.
•Thick, strong & smooth - black oxide finish is shiny and low friction, with a mysterious sheen.
