Description of Nickel Titanium Alloy Tubes

What is Nitinol Tube?Medical & Industrial Grade Nickel-Titanium Shape Memory Alloy Tubing

Nickel Titanium (also known as Nitinol or NiTi) is a unique class of shape memory alloys exhibiting extraordinary properties due to a thermoelastic martensitic phase transformation. Nitinol tubes are typically composed of 55%-56% Nickel and 44%-45% Titanium, with minor composition variations significantly influencing the material's transformation temperatures and performance.

As a trusted Nitinol tube supplier, DLX offers high-quality nickel titanium alloy tubes in seamless and welded forms. These nickel titanium shape memory alloy tubes are ideal for applications demanding superior flexibility, kink resistance, and biocompatibility, such as cardiovascular stents, catheters, guidewires, and aerospace actuators.

Characteristics of Shape Memory Effect in Nitinol Tubes

1. Shape Memory Effect

Returns to its programmed shape upon heating, making Nitinol tubes essential for self-expanding medical devices and adaptive structures.

2. Superelasticity

Exhibits pseudoelastic behavior, allowing large deformations without permanent damage, perfect for nickel titanium alloy tube applications in minimally invasive surgery.

3. High Corrosion Resistance

Resists degradation in harsh environments, including bodily fluids, seawater, and chemical exposures, ensuring long-term reliability in nickel titanium shape memory alloy tubes.

4.Biocompatibility

Meets ASTM F2063 standards, ensuring the NiTi tube is safe for surgical implants, catheters, and long-term medical applications.

5.High Durability

The high-performance shape memory alloy tube withstands repeated deformation-heating cycles, ensuring long-term reliability in NiTi tube applications.
