Nitinol Flat Wire for Precision Medical and Industrial Applications
Our nitinol flat wire is a high-performance nickel titanium alloy product designed for demanding medical and industrial use. Manufactured to ASTM F2063 standards, this medical-grade material offers exceptional biocompatibility, superelasticity, and shape memory capabilities, making it ideal for applications ranging from cardiovascular implants to aerospace actuators.
Material Specifications of Medical-Grade Nitinol Flat Wire
This nickel titanium flat wire is engineered using NiTi alloy with a controlled composition (Ni 54–57%). Its innate biocompatibility and ability to return to a preset shape after deformation make it a prime choice for surgical tools, implants, and robotic systems.
Surface Finishes for Nitinol Flat Wire
We offer a range of surface finishes to optimize the performance of our flat NiTi wire:
Polished Finish – Minimizes friction in catheter-based tools
Etched Surface – Improves coating adhesion for multifunctional applications
Oxide-Free Finish – Ensures maximum corrosion resistance in physiological and chemical environments
All finishes maintain precise dimensional control and eliminate micro-defects on the wire surface.
Precision Dimensions and Tolerances
Haolu’s flat wire is available in widths from 0.001875 mm to 5.0 mm, with a precision tolerance of ±0.00762 mm. Whether you need ultra-thin wire for neurovascular devices or thicker variants for aerospace components, each dimension is manufactured to meet strict consistency, flatness, and mechanical integrity standards.
