The shape is controlled by temperature.
Shape memory alloy springs are springs made using special alloys such as Ni-Ti. Once a specific shape is memorized, they have the property of returning to their original shape even after being deformed due to temperature changes or other factors.
Furthermore, this property can be utilized for temperature-dependent operation control and as a drive mechanism.

FAQ
Is it suitable for use in corrosive environments?
Ni-Ti-based shape memory alloy springs (SMA) have excellent corrosion resistance and can be used in many corrosive environments.
However, under certain conditions, such as a chloride-rich environment, it may be affected by corrosion fatigue.
What is the operating temperature range?
There is no single, fixed operating temperature range.
The applicable temperature range and tolerances vary depending on the material, manufacturing conditions, and specifications.
