Nitinol wire | muscle wire | memory wire | smart wire | actuator wire | nitinol elastic wire

As one of the most common uses for Nitinol, both the straight annealed nitinol wire and cold worked nitinol wire (as-drawn) states are available.

Due to nitino’ shape memory effect and super-elastic properties, it can get amazing many innovative solutions.

Available Diameter(mm)

Min | Max

0.015mm | 20mm

Suggestion recomend diameter

0.5mm is perfect for small robotic actuator and model making;

1mm wire is good for demonstration and can lift several pounds ( if employing linear stretch);

2mm wire can do some damage. It will jump out of a cup of hot water and even break glass beakers in the process;

Application

Its specific (weight-related) performance significantly exceeds those of electric motors. The heating is carried out by electrical current. There are also many interesting ideas, the material can be used as a heat engine or as a complete control circuit (sensor, regulator, actuator) in thermally switching valves.

Some advices for new user to nitinol

The recommended wire to get is the 40°C and 80°C wires. The 40°C will move with very little heat and is a pleasure to play with. The 80°C wire can be activated with a small flame or a hair dryer, and unlike the 40°C, it is very soft and malleable at room temperature
