Key Features
Shape Memory Effect: Allows the wire to return to its original shape after deformation when heated.
Superelasticity: Enables the wire to undergo large deformations and return to its original shape without permanent deformation.
Biocompatibility: Makes it suitable for medical implants.
Corrosion Resistance: Provides durability and longevity in various environments.
Packing
Packed in plywood boxes
Application
Stents: Nitinol stents are widely used in cardiovascular, neurovascular, and peripheral vascular interventions.
Guidewires: Nitinol guidewires provide flexibility and torque control during minimally invasive procedures.
Orthodontic wires: Nitinol arch wires apply continuous gentle force to move teeth, leading to more efficient and comfortable orthodontic treatment.
Embolization coils: Used to block blood flow in vessels during embolization procedures.
Micro-actuators: Nitinol’s shape memory effect allows it to be used in micro-actuators for applications like microfluidics, robotics, and MEMS devices.
Temperature sensors: The transformation temperature of Nitinol can be tailored, allowing it to be used as a temperature sensor in various applications.
Eyeglass frames: Nitinol frames are lightweight, durable, and can return to their original shape after bending.
Cell phone antennas: Nitinol antennas can be designed to be compact and then expand to improve signal reception.
Underwire bras: Nitinol underwire provides comfort and support while conforming to body shape.
