Product Overview: Superelastic Nitinol Tube for Guidewires and Catheters
Our NiTi Tube ASTM F2063 represents the pinnacle of superelastic nitinol technology for medical device manufacturers. This nickel-titanium alloy tubing combines shape memory effect with outstanding superelastic properties, making it the material of choice for high-performance guidewires, catheters, stents, and endovascular tools.
Compliant with ASTM F2063 specifications, the tubing delivers consistent chemical composition, mechanical strength, and transformation temperatures optimized for body temperature applications. Its ability to recover from up to 8-10% strain without permanent deformation ensures exceptional durability in repetitive stress cycles, reducing risks in procedures like angioplasty, embolization, and stent deployment.
Whether for peripheral vascular interventions or neurovascular access, this superelastic nitinol hypotube offers unmatched torque transmission, pushability, and biocompatibility – enabling safer, more effective minimally invasive treatments.

1.What is ASTM F2063, and why is it important for nitinol tubing?
ASTM F2063 is the international standard specifying chemical, mechanical, and metallurgical requirements for wrought nickel-titanium shape memory alloys used in medical devices and surgical implants. Compliance ensures biocompatibility, consistent superelasticity, and safety for applications like guidewires and catheters.
2.What makes superelastic nitinol ideal for guidewires and catheters?
Superelastic nitinol can deform significantly under stress and instantly recover its shape, providing kink resistance, flexibility, and reliable performance in tortuous anatomy during minimally invasive procedures.
3.Is this nitinol tube biocompatible?
Yes, our NiTi tube meets ASTM F2063 medical-grade requirements, offering excellent biocompatibility and corrosion resistance for long-term implantation.
4.What are the typical transformation temperatures?
Active austenite finish (Af) temperatures are optimized for body temperature (around 22-37°C), enabling superelastic behavior in physiological conditions.
5.Can this tubing be customized?
Yes, we offer various diameters, wall thicknesses, surface finishes (e.g., oxide-free, etched), and lengths to suit specific medical device needs.
