Our superelastic Nitinol Wire is a game-changer for stents and guidewires, making minimally invasive procedures smoother and safer. Nitinol, a nickel-titanium alloy, is famous for its superelasticity—meaning it can bend like crazy and snap back to its original shape without kinking. With a nickel content of 54.5-57.0% and a transformation temperature range of -25°C to 35°C, our wire meets ASTM F2063 standards, ensuring top-notch biocompatibility and performance. Whether it’s deploying a stent in a narrow artery or guiding a wire through complex vessels, our Nitinol wire delivers precision you can trust.

What makes our wire stand out? It’s built for flexibility and reliability. With tensile strength of 1000-1400 MPa and excellent fatigue life, it’s perfect for medical devices that need to navigate tricky anatomy. We’ve optimized it for vascular stents and guidewires, where superelasticity is critical for success. Our rigorous quality control ensures every batch is corrosion-resistant and biocompatible, with a smooth surface finish to minimize complications. When it comes to stents and guidewires, our Nitinol wire is the go-to choice for surgeons and manufacturers.

Our Nitinol wire is a carefully crafted blend of nickel (54.5-57.0%) and titanium, delivering the superelasticity and shape memory that make it ideal for stents and guidewires. The transformation temperature range (-25°C to 35°C) is tuned for body-temperature performance, ensuring the wire flexes and recovers perfectly during procedures. Compared to stainless steel or pure titanium, our Nitinol is a cut above. Stainless steel is strong but prone to kinking in tight spaces, while pure titanium lacks the flexibility and superelasticity needed for dynamic devices.

Our wire’s corrosion resistance is exceptional, standing up to bodily fluids without degrading. Its high fatigue life ensures it can handle constant stress, like a stent expanding with every heartbeat. With an elongation range of 10-20%, our wire balances flexibility and strength, making it perfect for applications like guidewires navigating tortuous vessels. We also offer customization options, like adjusting transformation temperatures or surface properties, to meet specific device needs, all while maintaining ASTM F2063 compliance for medical safety.
