Description
Nitinol Alloy Tube – High-Quality Shape Memory for Stents
Nitinol Alloy Tube Material
Our nitinol alloy tube uses high-purity nickel-titanium alloy (Ni55Ti45). It has superelasticity and shape memory. It is biocompatible, non-toxic and corrosion-resistant. It meets ASTM F2063 and ASTM F2082 standards for medical and industrial use.

How is Nitinol Tubing Made?
We make nitinol tubing in 5 simple steps. First, prepare nickel-titanium alloy materials. Then form the alloy into thin tubes with extrusion. Next, heat treat the tube to activate shape memory and superelasticity. Then use cold drawing to get final dimensions. Finally, anneal and test to ensure quality.

What is a Nitinol Tube for Stents?
Nitinol alloy tube is ideal for stents. Its shape memory lets stents return to original shape after deformation. Its superelasticity helps stents fit blood vessels well. It supports vessel walls and keeps blood flowing smoothly. It is safe for long-term use in cardiovascular treatments.
