Nitinol Wire Shape Memory Alloy

Nitinol is a nickel-titanium alloy that has the unique ability to remember its original shape after it has been deformed. This phenomenon is known as shape memory and is due to the material's crystal structure. shape setting nitinol is often used in a variety of industries, including medical devices, aerospace, and robotics.

The shape memory effect of Nitinol wire can be explained by two different temperature-dependent phases: austenite and martensite. At high temperatures, Nitinol wire is in its austenite phase and has a specific shape. When it is cooled below a specific temperature, called the transformation temperature, Nitinol undergoes a phase change and transforms into its martensite phase, which has a different shape. However, if the martensite phase is deformed while it is in the low-temperature state, nitinol wire will remember that shape when it is heated back up to its austenite phase.

Overview:

Properties:

•Chemical composition: Ni:55.4%-56.2% C:≤0.07 H≤0.005 O≤0.05 N:≤0.05 Ti: Remain

• Physical properties:tensile strength:850Mpa ,Yield strength:195-690Mpa, Elongation:25-50%

Product details:

This property makes Nitinol wire an ideal material for a variety of applications where shape memory is desirable. For example, Nitinol wire can be used in medical devices such as stents that are inserted into the body while in a compressed state and then expand back to their original shape once they are warmed by body heat. Nitinol wire can also be used in robotics and aerospace applications where the material's shape memory allows for precise movement and positioning.

In summary, Nitinol wire's shape memory is due to its ability to undergo a phase change between austenite and martensite phases, allowing it to remember its original shape after deformation. This property makes Nitinol wire a valuable material for a wide range of applications.
