What are the differences between nitinol SMA rods and other metal alloys?
Nitinol niti sma rod and other metal materials mainly have the following differences:
Shape memory performance
Nitinol rod has shape memory effect. Under the right temperature conditions, even if there is a large
deformation, when the temperature returns to a certain range, it can automatically return to the original
shape. Most common metal alloys remain basically the same after deformation.
hyperelasticity
- Nitinol rods are extremely flexible. In a certain strain range, the material exhibits nonlinear elastic behavior
and can withstand large strains without permanent deformation. However, steel and other common metal
materials will produce plastic deformation after exceeding the elastic limit, which cannot be recovered.
biocompatibility
Nitinol has good biocompatibility and is widely used in medical fields, such as making blood vessel stents and
orthodontic wires. Certain metal alloys may cause rejection or toxic reactions in the human body.
