Superelastic Nitinol Tubing:0.22mm x 0.42mm Superelastic Nitinol Micro Tube

Description

Superelastic Nitinol Tubing: Ultra-Precision in a Tiny Package

Explore the unmatched performance of our Superelastic Nitinol Tubing. With an inner diameter of just 0.22mm and an outer diameter of 0.42mm, this micro-dimension tubing is engineered for high-stakes applications that demand precision, flexibility, and durability. It bends with ease and instantly returns to its original shape—thanks to the remarkable property known as superelasticity.

Designed for Complex Medical Applications

In modern medicine, space is at a premium. Devices that enter the human body must be ultra-small and incredibly strong. That’s why our 0.22mm x 0.42mm superelastic nitinol tubing is ideal for:

• Catheters navigating narrow vessels

• Guidewires used in minimally invasive surgeries

• Tools for ophthalmic and neurological procedures

• Orthodontic wires applying continuous gentle force

This tubing serves as a fluid delivery path, a structural support, or a protective sheath—enabling faster healing and less patient trauma.

Industrial-Grade Versatility

Beyond medicine, this tubing shines in other demanding fields. It’s trusted in:

• Micro-actuators for robotics

• Aerospace systems under stress

• Microfluidic channels for controlled liquid flow

Wherever reliability in a small space is required, superelastic nitinol tubing delivers long-lasting performance.

What Makes It “Superelastic”?

Nitinol is a smart alloy of nickel (Ni) and titanium (Ti). It shifts between two crystal phases: Austenite (strong and original shape) and Martensite (flexible under force). At body temperature, it stays in Austenite. When force is applied, it converts to Martensite and bends. Release the stress—and it snaps back. This reversible transformation creates superelasticity, allowing the tubing to endure repeated deformation without permanent shape change.

Built with Quality from the Inside Out

Every tube starts with certified medical-grade Nitinol. Through advanced drawing, sizing, and heat treatment, we achieve tight tolerances and repeatable mechanical properties. Each batch meets strict dimensional and performance standards—so you get tubing you can trust.

We offer multiple options tailored to your needs:

• Standard Superelastic – Excellent springback and kink resistance

• High Fatigue Resistance – For devices under continuous flexing

• Radiopaque Grades – Easily seen under X-ray for device tracking

• Custom Alloys – Tailored to your specific performance requirements

The Smart Metal for the Smartest Devices

Nitinol is more than just a memory metal. While this tubing uses its cold-state superelasticity, the material also features shape memory—recovering its shape with heat. Understanding both effects gives you flexibility in design and performance.
