Nitinol is a super metal made from nickel and titanium. This is an unique metal because it will change shape and return back to its original state when it is heated or cooled. That means that Nitinol comes with some really cool features. Its trademark superelasticity and shape memory set it apart. These characteristics allow nitinol to be beneficial in various scenarios.
How Nitinol Works?
Nitinol’s shape memory allows it to bend and twist, and then return to its previous shape when heated. That's due to the special atomic-level structure of Nitinol. Atoms are the tiny bricks that make up everything around us. Nitinol's structure allows it to shift shapes based on temperature. So when you switch the temperature, metal can change form. This unique property allows it to return to its authentic form when heated.
What is Superelasticity?
Superelasticity is a fancy way of saying that Nitinol can withstand a great deal of bending without permanent deformation. If you take a piece of soft clay and bend it, it can stretch and be reshaped, but it might snap if you push too hard. Things are different with nitinol wire. It can bend a lot and then return to its original shape instead of breaking when stretched too much. This property is extremely useful for manufacturing medical instruments such as stents.
Stents are tiny devices that doctors place inside blood vessels. They can be compressed to fit inside a person’s body. After the stent is properly positioned, it expands to its original shape. This helps to keep the blood vessels open and blood flowing smoothly. That’s just one way Nitinol’s superelasticity assists medicine.
How Nitinol Changes Shape?
When Nitinol is bent, the little components within the metal known as atoms shift and change locations. It is this movement that causes the metal to change shape. It’s like when you push on a soft sponge: the sponge changes shape when you push on it, but once you stop pushing, it regains its shape.
When heated, the atoms move back to their original positions in Nitinol. This process is what allows the metal to be back to its normal state. That's right, nitinol memory shape spring is not just an ordinary metal, it has some unique properties that allows if to deform and returns back to its original shape.
Uses of Nitinol
The distinct characteristics of Nitinol find applications in multiple domains. A composite· tool, stent is also used on airplanes and engines that need strong materials. In the aerospace industry, Nitinol is known for components up to spec under high pressure and strain, for example.
The ability of Nitinol to remember its shape makes it great for robots and other machines too. Nitinol has useful applications in robotics for components that must move quickly and change shape. It enables flexible, efficient designs for robotic systems.
