Nitinol is a type of metal alloy that is associated with superelasticity, which is able to
withstand extreme stress without changing its shape due to its elastic properties.This
is a super elastic alloy that can be strained up to eight times more than ordinary spring
steel without permanent deformation.
Dia.0.015mm~20mm
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;
it can get amazing many innovative solutions
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.
