Nitinol Memory Spring

Nitinol memory spring, also known as shape memory alloy spring, is a special alloy material composed of nickel and titanium alloy. The biggest feature of this material is that it can remember a specific shape before heating and cooling, and once the preset temperature range is reached, it can automatically return to the previous shape.

Nickel titanium memory spring, full name shape memory nitinol spring, is a spring with superelasticity and memory function. Its superelasticity comes from the structural changes of the lattice, while the memory function comes from the ability of the material to "remember" its original shape and self-recover under certain conditions. In addition to memory nickel-titanium springs, our common nitinol springs include unidirectional nitinol shape memory springs, bidirectional shape memory nickel-titanium springs, nitinol tension springs, nitinol thrust springs, and superelastic nitinol springs.

In short, shape memory nickel-titanium springs have strong memory and superelasticity and are widely used in various fields. Its physical properties, working principles, phase change temperature and other factors will even affect the design and performance of the product, so extra caution is required during the manufacturing process.

The working principle of shape memory nitinol springs is based on the memory effect of nitinol alloy. When heated, the lattice structure in the Nitinol alloy changes, causing it to return to an open state from its original curled state. After cooling, the lattice rearranges, causing the Nitinol spring to curl back to its original shape. Its phase transition temperature varies according to different application requirements and manufacturing processes, usually between -10°C and +80°C.

The so-called superelasticity and memory of the NiTi spring refers to its superelasticity and memory, which means that it can not only withstand high stress and deformation, but also remember the shape, restore the structure and repeat thermal contraction and cold stretching. These characteristics make NiTi memory springs widely used in fields with high requirements for reliability and long life.

1.Medical devices: Shape Memory Nitinol spring is used in various medical devices such as stents, hooks, dilators, clips, catheters, shapers, etc. for the treatment of heart diseases, vascular diseases, orthopedics, ophthalmology, and ENT.

2.Automobile industry: It is used in automobile braking systems to improve vehicle braking performance and safety.

3.Household appliances: Superelastic nitinol spring is used in home appliances, such as hair dryers, electric irons, electric toothbrushes, etc. Adding this spring can increase the flexibility and durability of the product.

4.Safety control devices: Niti Spring is used in safety control devices, such as fault current protectors, circuit breakers, etc., as spring switching elements.

5.Shape Memory Nickel Titanium springs can also be used in mechanical movement, adjustment of car seats, smart materials, etc.
