There are four commonly used types of applications for nitinol.

• Free Recovery: nitinol is deformed at a low temperature, and heated to recover its original shape.

• Constrained Recovery: The same, except that recovery is rigidly prevented, and thus a stress is generated.

• Work Production: Here the alloy is allowed to recover, but to do so it must act against a force (thus doing work).

• Superelasticity: As discussed above, here the nitinol acts as a super spring.

Product performance description

Nitinol actuator wire can help the SMA OIS significantly eliminates blur caused by hand shake and enables impressive low light photos.

Nitinol SMA actuator wire, whose physical function resembles biological muscle, will contracts when it is activated.

> For heating it electrically, the wire will be activated when thetemperature is above its transition temperature.

> When the material cools, it can be stretched back to its original length for subsequent contractions.

> The small size, light weight, ease of use and silent operation allow it to replace small motors or solenoids.

Nitinol (Nickel and titanium alloy) introduction

Nickel Titanium (also known as Nitinol or NiTi) is in the unique class of shape memory alloys. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties. Nitinol alloys are typically made of 55%-56% Nickel and 44%-45% Titanium. Small changes in composition can significantly impact the properties of the material.

There are two primary categories of Nitinol. The first, known as "SuperElastic", is characterized by extraordinary recoverable strains and kink resistance. The second category, "Shape Memory" alloys, is valued for the Nitinol's capacity to recover a pre-set shape when heated above its transformation temprature.

The first category is often used for orthodontics (braces, wires, etc) and eyeglasses. The first category are primarily useful for actuators, used in many different mechanical devices.
