TINI Shape Memory Nitinol Wire Nickel Titanium Alloy Wire for temperature control of the original
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.

How does nitinol work?

Nitinol Shape Memory Alloys undergo a phase transformation in their crystal structure when cooled from the stronger, high

temperature from (Austenite) to the weaker, low temperature from (Martensite). This inherent phase transformation is the basis for
the unique properties of these alloys - in particular, Shape Memory and Superelasticity.

Shape Memory
When shape memory alloys are in their martensitic form, they are easily deformed to a new shape. However, when the alloy is heated
through its transformation temperatures, it reverts to austenite and recovers its previous shape with great force. This process is
knows as Shape Memory. The temperature at which the alloy remembers its high temperature from when heated can be adjusted by
slight changes in alloy composition and through heat treatment. In the Nickel Titanium alloys, for instance, it can be changed
from above +100 deg. C to below -100 deg. C. The shape recovery process occurs over arange of just a few degrees and the start or
finish of the transformation can be controlled to within a degree or two if necessary.


These unique shape memory alloys also show a Superelastic behavior if deformed at a temperature which is slightly above their
transformation temperatures. This effect is caused by the stress-induced formation of some martensite above its normal
temperature. Because it has been formed above its normal temperature, the martensite reverts immediately to undeformed austenite
as soon as the stress is removed. This process provides a very springy, "rubberlike" elasticity in these alloys.

Product application
1. Nitinol spring: nitinol push and pull spring is a kind of spring used for orthodontic treatment. It has the characteristics of
nitinol super elasticity, and is suitable for orthodontic treatment, opening up the space between teeth and pulling teeth in
different directions. A force of about 50 g can be produced by extending the NiTi coil spring by 1 mm. NiTi coil spring has highelastic properties, which can produce soft and stable continuous force under tensile state. The force attenuation is very small,which can produce ideal orthodontic force for clinical tooth movement. Meet the physiological requirements. Compared with thestainless steel wire of the same diameter, the force released by the Ni Ti wire spring is 3.5-4 times lower. Therefore, in theapplication of orthodontic treatment, patients not only have mild pain, soft and lasting feeling power, but also reduce the returnvisit time, shorten the course of treatment and improve the curative effect. It is a new excellent mechanical device inorthodontic treatment.

2. Because of the super elasticity, shape memory and low stress-strain curve of nitinol archwire, nitinolarchwire is usually used as the initial archwire in orthodontic treatment system. In this way, the discomfort of patients will begreatly reduced. Because there are several kinds of straight wire orthodontic techniques, mbt technique recommends the use of
0.016 inch heat activated nickel titanium alloy arch wire (hant wire), demon self-locking bracket technique recommends the use ofcopper containing heat activated nickel titanium alloy arch wire (phase transition temperature is about 40 ℃), 0.016 inch super elastic Ni Ti alloy arch wire is recommended for early alignment in o-pak.
