Product Overview:Superelastic Nitinol Tube
The DLX High Strength Superelastic NiTi Tube Medica is a premium nickel-titanium alloy (Nitinol) hypotube engineered for superior performance in minimally invasive medical applications. Combining exceptional superelasticity, shape memory effect, and high tensile strength, this medical-grade Nitinol tubing offers unmatched flexibility, kink resistance, and biocompatibility. Ideal for cardiovascular stents, catheter reinforcements, guidewires, and other precision medical devices, it ensures reliable deformation recovery and long-term durability in demanding clinical environments. Compliant with ASTM F2063 standards, this superelastic NiTi tube delivers the strength of metal with plastic-like flexibility for life-saving interventions.
This superelastic Nitinol tubing excels in environments requiring extreme flexibility and recovery, such as vascular navigation and implantable devices. With its unique phase transformation properties, it withstands strains up to 8-10% while returning to its original shape, far surpassing traditional stainless steel or titanium materials. Biocompatible and corrosion-resistant, this high-strength NiTi alloy tube supports minimally invasive procedures, reducing patient trauma and improving outcomes in cardiology, endoscopy, and orthopedics. Engineered for precision, it features tight tolerances, smooth surfaces, and excellent fatigue resistance, making it the preferred choice for next-generation medical hypotubes and shape memory alloy components.

1.What is nitinol and why is it used in endoscopic instruments?
Nitinol (nickel-titanium alloy) is prized for its superelasticity and shape memory properties, allowing nitinol tubes to bend extensively without kinking and recover shape instantly—essential for flexible, reliable endoscopic medical devices.
2.Is medical nitinol tube biocompatible?
Yes, our medical-grade nitinol tubing features excellent biocompatibility due to its protective titanium oxide layer, making it safe for implants and long-term contact in minimally invasive procedures (compliant with biocompatibility standards like ISO 10993).
3.What makes this nitinol tube superelastic?
Superelasticity occurs above the austenite finish temperature, enabling up to 8-11% recoverable strain—far superior to stainless steel—ideal for kink-resistant performance in endoscopic hypotubes.
4.Can nitinol tubes be customized for specific endoscopic applications?
Absolutely. We offer customizable dimensions, Af temperatures, surface finishes, and laser-cut patterns for tailored high-precision nitinol tubing in catheters, guidewires, and surgical instruments.
5.How durable are superelastic nitinol tubes in repeated use?
Highly durable with exceptional fatigue resistance, our nitinol hypotubes withstand millions of cycles, supporting reusable endoscopic instruments without loss of performance.
6.What specifications ensure the quality of this high-strength NiTi alloy tube?
Manufactured with precise chemical composition (Ni55/Ti45), tight tolerances, and tested for tensile strength, superelastic plateau stresses, and active Af temperature for consistent medical performance.
