Product Description

Superelastic Nitinol Alloys / Shape memory Nitinol alloys  / Nitinol Memory Wire 

Superelastic shape memory Ni Ti alloy nitinol fishing gear wire/line

Nickel Titanium (also known as Nitinol or NiTi) is in the unique class of shape memory alloys. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties. Nitinol alloys are typically made of 55%-56% Nickel and 44%-45% Titanium. Small changes in composition can significantly impact the properties of the material. There are two primary categories of Nitinol. The first, known as "SuperElastic", is characterized by extraordinary recoverable strains and kink resistance. The second category, "Shape Memory" alloys, is valued for the Nitinol's capacity to recover a pre-set shape when heated above its transformation temprature. The first category is often used for orthodontics (braces, wires, etc) and eyeglasses. we makes shape memory alloys, which are primarily useful for actuators, used in many different mechanical devices.

Application

Nitinol wires Applications:

There are four commonly used types of applications for nitinol.

  • Free Recovery: nitinol is deformed at a low temperature, and heated to recover its original shape.
  • Constrained Recovery: The same, except that recovery is rigidly prevented, and thus a stress is generated.
  • Work Production: Here the alloy is allowed to recover, but to do so it must act against a force (thus doing work).
  • Superelasticity: As discussed above, here the nitinol acts as a super spring.

 Other applications

  • Nitinol is also popular in extremely resilient glasses frames. It is also used in some mechanical watch springs.
  • It can be used as a temperature control system; as it changes shape, it can activate a switch or a variable resistor to control the temperature.
  • It is used in cell-phone technology as a retractable antenna, or microphone boom, due to its highly flexible and mechanical memory nature.                                                            
  • It is used in some novelty products, such as self-bending spoons which can be used by amateur and stage magicians to demonstrate " psychic" powers or as a practical joke, as the spoon will bend itself when used to stir tea, coffe, or any other warm liquid.                                                                                               
  • It can also be used as wires which are used to locate and mark breast tumours so that following surgery can be more exact.
  • Due to the fact it can change shapes it is also used as a golf club insert.
  • Nickel titanium can be used to make the underwires for underwire bras.
