Features :
Shape memory: Nitinol spring can be deformed at low temperatures and then regain its original shape when heated above a certain temperature, making it useful in applications where shape recovery is required.
Superelasticity: Nitinol spring exhibits superelasticity, which means it can undergo large deformations and then return to its original shape without permanent damage.
Biocompatibility: Nitinol spring is biocompatible, making it suitable for medical applications such as stents, orthopedic implants, and dental braces.
Corrosion resistance: Nitinol spring has excellent corrosion resistance, making it suitable for use in harsh environments.
High strength and durability: Nitinol spring has high strength and durability, making it suitable for use in applications where high stress and fatigue resistance are required.
Applications :
Medical devices: Nitinol spring is widely used in medical devices such as stents, catheters, and orthopedic implants, due to its biocompatibility, shape memory, and superelasticity.
Aerospace industry: Nitinol spring is used in the aerospace industry for applications such as actuator systems, control surfaces, and landing gear due to its high strength and durability.
Robotics: Nitinol spring is used in robotics for actuation and sensing applications due to its shape memory and superelasticity.
