Nickel Titanium Spring

Our nickel titanium spring is a spring made of a alloy material made out of two metal components: titanium and nickel. It has superelastic and excellent shape memory properties. After being deformed by an external force, this kind of spring can automatically return to its original shape. It can realize shape change and recovery in different application environments according to preset temperature and external force conditions,Shape memory springs have the low flexible modulus, and high wear obstruction, and are generally utilized in aviation, apparatus, electronic gear, clinical and different fields.

superelastic effect
When the shape memory alloy is subjected to external force, it will undergo plastic deformation. After the external force is removed, the memory alloy will return to its original shape. This effect is called the superelastic effect. When the shape memory alloy undergoes superelastic deformation, it will induce martensitic transformation, and when the external force is removed, the inverse Martensitic transformation will occur.

Damping characteristics
Shape memory alloys generate a large number of martensite variants with the same structure and different orientations due to thermoelastic martensitic phase transformation, and the interface energy between the variants and the twin interface energy within the martensite are very low. Compared with It is easy to migrate and can effectively attenuate external mechanical energy such as vibration and impact. Therefore, shape memory alloys have particularly good damping properties and can be used as shock-proof materials and sound-absorbing materials.

Resistance characteristics
Research shows that for nickel-titanium alloys whose initial structure is martensite, there is a linear relationship between resistance and strain during the stretching process; for nickel whose initial structure is austenite or a mixture of austenite and martensite, For titanium alloys, when stress-induced martensitic transformation occurs, the slope of the curve will decrease, and the resistance-strain relationship remains linear before and after phase transformation.
