Le Nitinol combine deux caractéristiques uniques associées : mémoire de forme et super élasticité.
Shape memory gives Nitinol the ability to be deformed at one temperature, and then return to its original shape when being heated to its transformation temperature. This effect is caused by the material changing from its low temperature monoclinic martensitic structure to the high temperature cubic austenitic structure. Transformation temperatures in our finished Nitinol wire range from -15°C to +22°C, depending on the grade of Nitinol used.
Shape memory Nitinol wire can be used to develop implants that may be delivered into the body in a compact shape and then activated into their functional form once they have been deployed. If you need the wire to be in a certain shape for a particular application, we offer Shape Setting. This “sets” a wire shape that specifically conforms to your device design requirements.
Not only do we manufacture Nitinol in various forms, we control the entire process, from start to finish, by being the world's leading melt-to-finish source for Nitinol to the medical device industry.
