Nitinol Tube
Nitinol shape memory alloy is composed of nearly equal atomic nickel and titanium (i.e. 50:50 at% nickel and titanium), with excellent superplastic and shape memory properties, as well as excellent characteristics of biocompatibility, wear resistance, corrosion resistance, high damping, etc., thus becoming a key material in the field of vascular, orthopedics, spine, urology and dentistry. Applications range from neurovascular stents and heart valve frames to orthopedic nails and disposable suture threading devices.

Material Properties
- Super elasticity: It can withstand great deformation and restore its original state in the body, which is several times that of other metals.
- Shape memory effect: It can automatically recover from a deformed state to a pre-set shape at a specific temperature.
- Excellent biocompatibility: Good compatibility with human tissues, less likely to cause rejection or allergic reactions.
- Good flexibility: The pipe is soft and easy to pass through tortuous and narrow human blood vessels or cavities.
- Fatigue resistance: able to withstand cyclic loads for a long time without easily breaking, with a long service life.
- Magnetic resonance compatibility: It will not move or generate heat in a magnetic field, and can safely undergo nuclear magnetic resonance examination.
- High corrosion resistance: It can resist the corrosion of human body fluids and maintain long-term stability.
