1. Household items

In household goods, the application of Nitinol wire can make some ordinary items more intelligent. For example, in curtain design, Nitinol wire can be used as a regulator to automatically open or close curtains in response to changes in sunlight. In this way, life at home will be more convenient.

 

2. Clothing and accessories

In fashion design, nickel-titanium alloy wire also has a great role. Imagine a coat that automatically adjusts its thickness according to the weather, so that you don't feel too hot and you don't get chills on a cold day. Technology like this could revolutionize the fashion world! In addition, Nitinol wire can also be used in jewelry design, creating both beautiful and comfortable accessories, attracting the attention of many consumers.

 

3. Toys and children's items

Many parents tend to consider safety and durability when choosing toys. The durability and toughness of Nitinol wire just meet these two needs. We may wish to imagine some children's toys that can change shape with the growth of children, which can accompany the growth of children, and will not be damaged by improper use. Such a design, isn't every parent looking forward to?

 

Because shape memory alloys not only have unique shape memory functions, but also have the advantages of hyperelasticity, high damping, wear resistance and corrosion resistance, they are widely used in many fields, such as machinery, architecture, aerospace, automobile, medical treatment and so on.

 

Shape memory effect of Nitinol wire

If you bend an ordinary wire, can it return to its original shape? However, the Nitinol wire can remember its previous shape and automatically recover when heated to a certain temperature This allows Nitinol wires to easily adapt to different environments and needs when manufacturing complex medical devices.

 

Superelastic property

In addition to the shape memory effect, Nitinol wire has a very surprising property - superelasticity. Imagine that an ordinary spring can always recover after being stretched, but the Nitinol wire can remain elastic after large deformation. This characteristic makes it particularly good in fields such as medical wires and dental orthotics. You can think of it as a superhero, in the face of great pressure and challenges, still able to maintain its form and function, so that you feel its strength.

 

1,Mechanical engineering. The earliest application was in pipe joints and fasteners. At the connection of mechanical parts, the connection of pipes and the interface of aerial refueling of aircraft, Using shape memory alloy to produce sleeves with an inner diameter smaller than the outer diameter of the pipeline, and then expanding the sleeves at liquid nitrogen temperature. During assembly, take out the casing from liquid nitrogen and insert the pipe to be connected from both ends When the temperature rises to normal temperature, Electric heating can change the temperature, cause deformation of memory alloy at the interface, enhance the sealing performance of sleeve shrinkage, and result in better dripping than welding. It is especially suitable for aviation, aerospace, nuclear industry, ships and submarine oil pipelines In some parts with inconvenient construction, the pins are made of memory alloy and installed into the hole for heating, Using the memory alloy's unique temperature sensing performance and driving dual functions, you can make a robot

 

2. Aerospace industry. In the hydraulic system of American F - 14 aircraft, an average of 800 shape memory alloy joints are used per aircraft Since 1970, hundreds of thousands of such pipe joints have been used on U.S.In addition to manufacturing pipe joints, shape memory alloys are also used for spacecraft antennas and have a wide range of applications

 

3. Automobile industry. It is used for engine anti heat fan clutch, exhaust automatic regulating nozzle, automatic switch of diesel engine radiator hole, shape memory shell of jet engine suction filter, etc.

 

4. Medical devices. Shape memory alloys have been widely used in medical field because of their good mechanical properties and biocompatibility. In particular, NiTi shape memory alloy, with its good hyperelasticity and shape memory effect, has been successfully applied to oral and dental correction, surgical correction and plastic surgery, and minimally invasive interventional therapy of cardiovascular system. nitinol memory alloys can also be used to make thrombus filters. When the straightened filter is inserted into the vein, it gradually forms a network, which can block the clot from returning to the heart and lungs. Also in clinical trials are surgical sutures, dental orthopedic wires, cerebral aneurysm clips, intramedullary needles, artificial joints, contraceptive rings, micropumps for artificial hearts and kidneys.
