Nitinol Wire & Rod Description

Nitinol wire & Nitinol rod are the fabricating product of nickel-titanium alloy. Nitinol is well known for its thermo-mechanical properties of superelasticity and shape memory effect. Shape memory refers to the ability of Nitinol to undergo deformation at one temperature and then recover its original, under formed shape upon heating above its transformation temperature.

Super elasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the under formed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.

Nitinol Wire & Rod Applications

Nitinol Wire is used for many different medical and industrial applications. The table below gives some typical engineering applications for each of our standard Nitinol medical grades:

  1. Nitinol Wire is used in guidewires, stents, stylets, forming mandrels, stone retrieval baskets, orthodontic files, etc.
  2. Nitinol Wire is often used in applications that require a high loading and unloading plateau stress at room temperature. Chromium-doped for decreased transformation temperature and increased tensile strength.
  3. Nitinol Wire is used in applications requiring increased stiffness. Cobalt-doped for decreased transformation temperature and increased tensile strength.
  4. Nitinol Wire provides the best cycling performances at body temperature (37°C).
  5. A common application for Nitinol alloy is high-temperature actuators.
  6. A common application for Nitinol alloy is high-temperature actuators.
  7. Nitinol Wire/Rod is typically used in applications that require a phase transformation at body temperature (37°C).
  8. Nitinol Wire/Rod can be used in a very cold temperature environment.
