Nitinol Tube

Email us

Nitinol tubes are highly versatile and widely used components in various industries, especially in the medical and engineering sectors. Made from a special alloy of nickel and titanium, Nitinol is known for its unique shape-memory and superelastic properties, making it ideal for applications that require flexibility, strength, and durability.
Key Features:

-Superelasticity: It can withstand significant deformation without permanent damage, making it extremely resilient under stress.
-Biocompatibility: Nitinol tubes are non-toxic, making them highly suitable for medical applications, including stents and implants.
-Corrosion Resistance: The alloy offers excellent resistance to corrosion, ensuring longevity in harsh environments.
-Lightweight and Strong: Despite being lightweight, Nitinol tubes have high tensile strength, which contributes to their reliability in various applications.

Active Austenite Finish Temperature of Nitinol Tubing
The austenite finish temperature of the finished NITINOL tube (active Af) with outer diameter in the range of 0.25mm to 7.0 mm (0.01 to 0.275 in.) shall be measured on representative full round tube sample(s) using the bend and free recovery method described in Test Method ASTM F 2082-15.

Mechanical Properties of Nitinol Tube

* Superelastic properties are measured per Test Method F2516 at room temperature (22+/-2℃)
* Applicable Standard: ASTM F2633

Surface Finish
-Outer surface: Black oxide or Center-less Ground.
-Inner surface: Etched or oxide.
Other finishes can be discussed with EdgeTech Industries.

Nominal Dimensions and Tolerances

* Other variation in OD and ID can be discussed.

Length
Nitinol tube can be delivered in either exact length or random length. For random length orders, a maximum and minimum length shall be discussed.

Straightness
Straightness requirements and measurement methods shall be discussed.

Permissible Outer and Inner Surface Imperfections of Nitinol Tube
Outer and inner surface imperfections criteria on tubes shall be discussed.
