Nitinol, a nickel-titanium based alloy, is one of the best known examples of shape memory materials. Thanks to a unique combination of components, Nitinol alloy can be purchased with unusual properties, such as the ability to return to a predetermined shape when heated.
Alloy – features and application
The main advantage of Nitinol, which can be ordered in any volume, is its ability to thermal and mechanical memory. This alloy can experience significant deformation, but at a certain temperature returns to its original shape. This property is widely used in the creation of self-expanding stents in medicine, elements in aviation and space technology, where materials must adapt to the conditions of use. Due to its corrosion resistance and biocompatibility, Nitinol is optimal for long-term use in the human body, making it an important material for implants and instruments.
The unique characteristics of Nitinol alloy make it possible to use it in a whole range of industries whose need for innovative products is becoming increasingly urgent. At the same time, the price for the Nitinol alloy is quite affordable, which makes choosing it a logical and expedient decision
