Customized Super Elastic Nitinol Tube for Medical Devices

Precision Nitinol Tubing Designed to Your Exact Specifications

Our factory specializes in Customized Super Elastic Nitinol Tubes manufactured to ASTM standards. These high-performance tubes are critical components in advanced medical devices, especially self-expanding stents used in minimally invasive vascular treatments.

Rather than offering off-the-shelf tubing, we tailor each super elastic nitinol tube to your precise design requirements. This customized approach ensures predictable mechanical behavior, consistent expansion performance, and seamless integration into your final medical device.

Material Quality – ASTM F2063 Medical-Grade Nitinol

We use only premium nickel-titanium alloy (Nitinol) that complies with ASTM F2063, the international standard for wrought Nitinol used in medical devices. This carefully controlled alloy composition provides exceptional superelasticity, stable shape memory behavior, and outstanding corrosion resistance.

High metallurgical consistency ensures reliable transformation temperatures and repeatable mechanical performance. As a result, every customized super elastic nitinol tube behaves consistently from batch to batch, supporting regulatory compliance and long-term device reliability.

Superelastic Performance & Custom Parameters

Our Nitinol tubes are small-diameter, thin-walled hollow components engineered to deliver both superelasticity and shape memory effect. By precisely controlling the austenite finish temperature (Af), often near body temperature, we ensure optimal performance for implantable medical applications.

Key parameters can be fully customized, including:

• Outer diameter (OD)

• Inner diameter (ID)

• Wall thickness

• Tube length

• Mechanical response and radial strength

The tube offers excellent crush resistance and full shape recovery, even after significant deformation.

Product Description – Foundation for Self-Expanding Stents

The Customized Super Elastic Nitinol Tube is the primary raw material for manufacturing self-expanding stents. At body temperature, the tube exists in the austenite phase, where it exhibits high strength and superelastic recovery.

After laser cutting precise mesh patterns, the tube transforms into a stent framework. When compressed onto a catheter, it stores elastic energy. Once deployed inside the vessel, it expands automatically, applying a gentle and continuous outward force to restore and maintain blood flow.

Our tubes feature smooth, clean surfaces optimized for laser cutting, electropolishing, and secondary processing, ensuring consistent downstream manufacturing results.

Advanced Manufacturing Capabilities

We specialize exclusively in customized Nitinol tubing. Production begins with certified raw material and proceeds through precision pilgering and drawing processes, which gradually reduce tube diameter and wall thickness.

Intermediate and final heat treatments carefully control grain structure, transformation temperatures, and superelastic behavior. Dimensional accuracy is verified using laser micrometers and optical inspection systems. Mechanical and functional testing ensures compliance with your specifications.

Manufacturing is supported by cleanroom environments to maintain surface purity. We provide full support from early-stage prototyping through volume production, meeting the strict requirements of the medical device industry.
