Products Description
Basic knowledge of Shape Memory Alloy Ni-Ti Wire
Shape Memory Alloy Ni-Ti Wire is a shape memory alloy (SMA) composed of nickel (Ni) and titanium (Ti), renowned for its unique shape memory effect (SME) and superelasticity (pseudo-elasticity). At a specific temperature, it can restore its pre-set shape or undergo significant elastic deformation under force. It is widely applied in medical fields (such as dental archwires, vascular stents), aerospace, mechanical automation and consumer electronics, etc.
Feture of Shape Memory Alloy Ni-Ti Wire
Shape Memory Effect (SME)
After heating to the austenite transformation temperature (Af), restore the pre-set shape (such as bending, helical, etc.).
Superelasticity (pseudo-elasticity) :
It can withstand significant deformation (~8% strain) at room temperature (above Af) and fully recover without plastic deformation.
Biocompatibility
After surface treatment (such as oxidation passivation), it can be used for human implants (conforming to ASTM F2063 standard).
High damping performance
Absorb vibration energy and is suitable for shock absorption devices.
Temperature sensitivity
Performance is highly dependent on temperature and requires precise control of the environment or driving conditions.
