NiTi Wire & Tube

Medical-Grade Nitinol (Ni-Ti) Wires & Tubes for Next-Generation Medical Devices

Engineered for minimally invasive surgical instruments, medical-grade Nitinol (Ni-Ti) wires and tubes deliver exceptional super-elasticity, shape memory, and biocompatibility. From high-pushability vascular guidewires to ultra-smooth catheter lumens, these high-precision materials solve key mechanical challenges in complex anatomical navigation.


【Precision Medical Nitinol Tubes】

Ultra-Smooth Inner Surface Catheter Tubes: Advanced internal polishing achieves an inner surface roughness guaranteed at Ra ≤ 0.1 μm (reaching as smooth as 0.02 μm). This drastically reduces frictional resistance when passing micro-guidewires, implants, or fluids through the lumen.

Stent & Heart Valve Frame Tubes: Manufactured to strict ASTM F2633 standards with tight tolerances for roundness and wall concentricity. Ideal for laser-cutting self-expanding structural scaffolds used in TAVI/TAVR valve frames, peripheral vascular stents, and occluders.



【High-Performance Nitinol Wires】

High-Pushability & High-Rigidity Alloys: Advanced binary and ternary (Ni-Ti-Co) alloys providing up to three times the stiffness of standard Nitinol. Engineered with narrow stress hysteresis to prevent "whip" rotation and ensure maximum torque transmission in winding anatomy.

Radiopaque Pt-Cored Wires: Integrates a high-density Platinum core within a super-elastic Nitinol shell, delivering clear X-ray visibility under fluoroscopy without sacrificing kink resistance.

Standard Super-Elastic Wires: Fully compliant with ASTM F2063 standards, offering uniform elasticity, extreme fatigue resistance, and customizable surface finishes (pickled, oxide-free, or thin-oxide).



Rapid Prototyping & Customization Flexible Engineering: Fully customizable parameters, including transformation temperatures ($A_f$ point), tensile strength, outer diameters, and wall thicknesses. Agile Development Support: Dedicated quick-turn prototyping programs and stock tube inventories enable R&D teams to accelerate design iterations and shorten time-to-market.
