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.
Industrial applications: Nitinol spring is used in a variety of
industrial applications, including actuators, valves, and springs,
due to its high strength and durability.
Consumer electronics: Nitinol spring is used in consumer
electronics such as smartphones and laptops for hinge and connector
applications due to its high strength and durability.
