Nitinol Spring

Nitinol springs are manufactured from nickel-titanium shape memory alloy (SMA), a unique material capable of recovering its original shape after deformation when exposed to a specific temperature.

With excellent elasticity, fatigue resistance, and damping properties, Nitinol springs are widely used in both industrial and medical applications where precision and reliability are critical.
