Exceptional Superelastic Performance

The superelasticity of nitinol memory alloy capillary tubes represents another critical advantage for flexible catheter designs. This property allows the tubes to undergo substantial deformation—up to 10 times more than standard stainless steel—and return to their original shape without permanent deformation once the stress is removed. This characteristic is particularly valuable for catheters that must navigate through complex anatomical structures while maintaining structural integrity. Our nitinol memory alloy capillary tubes exhibit superior fatigue resistance, capable of withstanding thousands of loading cycles without degradation, ensuring long-lasting performance in critical applications. This exceptional elasticity translates to catheters that can be maneuvered through tight bends and constrictions with significantly reduced risk of kinking or permanent deformation. The material's ability to distribute stress evenly throughout its structure prevents localized weak points that could lead to failure. Additionally, this superelasticity contributes to improved tactile feedback for physicians during catheter insertion and manipulation, enhancing procedural precision and control in delicate vascular interventions where millimeters can matter significantly.

Unmatched Biocompatibility and Corrosion Resistance

The biocompatibility of nitinol memory alloy capillary tubes makes them exceptionally well-suited for intravascular applications. These tubes form a stable titanium oxide layer on their surface, creating a protective barrier that prevents nickel leaching and minimizes potential allergic reactions. This inherent biocompatibility reduces the risk of adverse tissue responses during extended implantation periods. Furthermore, nitinol memory alloy capillary tubes demonstrate outstanding corrosion resistance, particularly in saline environments like bodily fluids. At Baoji Hanz Metal Material Co., Ltd., our nitinol products undergo rigorous testing to ensure they meet stringent ISO 13485:2016 medical device standards and EU CE certification requirements. This corrosion resistance is crucial for catheters that may remain in the body for extended periods, as it prevents degradation that could lead to material failure or the release of potentially harmful particles. The combination of biocompatibility and corrosion resistance contributes significantly to patient safety and device longevity, making nitinol memory alloy capillary tubes the material of choice for advanced catheter systems where reliability cannot be compromised.

Design Innovations Enabled by Nitinol Capillary Technology
