production & inspection of Nitinol Memory Wire
Production
1. First, the materials must be proportioned and smelted, and then cast into billets. The billet is then rolled into strips approximately the same width as the desired end product. The strip is then annealed to soften the material and make it more pliable during the drawing process.
2. The wire drawing process itself involves pulling nitinol wire through a series of progressively smaller dies. Each pull reduces the diameter of the wire and increases its length. As the wire is pulled, it also becomes stiffer and stronger.
3. An important factory in the Nitinol memory wire drawing process is maintaining a constant temperature. The wire must be heated and cooled at specific intervals to ensure it maintains its shape memory properties. Temperature control is critical to ensure that the wire maintains its required performance.
inspection
Nitinol Shape Memory Alloy wire phase change temperature test. The most important thing to check whether the Nitinol Shape Memory Alloy wire we produce meets the customer's requirements is to check its AF transition temperature. For example: The phase change temperature of nitinol wire is 60 degrees Celsius. We can take an appropriate amount of 60 degrees Celsius hot water and put our bent 60 degrees Celsius nitinol wire into the water to see if its changes can return to its original properties. The specific steps are shown in the figure.
application field of nitinol wire
01
Paragliders
Nitinol Wire is a material with excellent properties. It not only has a shape memory effect, but also has superelastic properties. The application of Nitinol Alloy wire in paragliders takes advantage of its superelastic properties. Superelastic Nitinol wire is extremely elastic at low phase transition temperatures, which is why it is so attractive as an alternative to nylon or plastic wire used inside paragliders. For example, Nitinol is a material that can be bent when folding an umbrella, but it always quickly returns to its original shape. The super elasticity of Nitinol alloy can be said to be very useful.
02
Grass frame
Nitinol wire is mainly used in the glass frame industry for its superelasticity, because superelastic nitinol wire can return to its original shape by itself after being stressed, so they can easily go back and forth to different shapes and sizes without worrying about damage. Nitinol alloy wire has excellent corrosion resistance and wear resistance, so the manufactured eyeglass frames can not only withstand the test of time, but also resist various physical and chemical damage in daily use.
03
fishing
Nitinol wire is a shape memory alloy that can not only restore its original shape after being stressed, giving the fishing wire better elasticity and durability, but is also corrosion-resistant and not easy to rust, and can be used for a long time in seawater or fresh water. Reduces the cost and hassle of replacing fishing wire. In addition, Nitinol fishing wire is tougher than other metal fishing wires and can withstand greater pulling and tearing forces, reducing the risk of line breakage or fish jumping during fishing.
04
jewelry
Due to nitinol has memory characteristics and super elasticity, nitinol wire becomes a jewelry material with high strength and high corrosion resistance, which can reduce the loss of jewelry, enhance service life, and save costs. Superelastic Nitinol flat wire offers ease of processing. Due to the high strength of this material, its elastic memory characteristics, and its ability to be deformed at will, Nitinol Alloy wire can be easily processed into various shapes during the jewelry manufacturing process, including special shapes, ovals, circles, etc., which provides great opportunities for jewelry. It provides convenience for designers to improve their creative space. As a result, the jewelry industry also has the flexibility to innovate products.
05
Medical
Nitinol wire has excellent biocompatibility. This means it is compatible with human tissue and does not cause any adverse reactions. Therefore, the use of Nitinol Alloy wire in medical equipment and surgery can effectively reduce the incidence of surgical complications and adverse reactions. Secondly, it has excellent elasticity and memory shape functions. Nitinol Superelastic wire can be compressed and twisted, but it still returns to its original form. This strong elastic property allows Nitinol guide wire to be used in a variety of applications in surgery, such as artificial heart valves, stents and intravascular applicators. In these applications, it also provides stable and long-lasting support.
06
Aerospace
The spacecraft's self-expanding antenna and span-adaptive wings made of Nitinol wire take advantage of the memory function, good ductility and conductivity of nitinol alloy. The antenna made of nitinol shape memory alloy wire is folded at low temperatures. After entering space, it can be re-expanded and restored to its original shape under sunlight. Engineers used nitinol memory alloy to fold the wings because it remembers different shapes when heated or cooled. Engineers completed flight tests using these new actuators.
