Description
Precision Black Oxidized Nickel Titanium Microfilament 0.055mm for Advanced Nitinol Medical Devices
Unlock unmatched performance for your next-generation nitinol medical devices with our expertly engineered Black Oxidized State Nickel Titanium Microfilament. With an ultra-fine diameter of 0.055mm, this microfilament is designed to meet the highest demands for flexibility, strength, and biocompatibility in critical medical applications.
Premium Medical-Grade Nitinol Material
This wire is made from top-grade nickel titanium alloy (Nitinol), renowned for its outstanding flexibility and consistent shape recovery. It withstands significant bending and flexing without permanent distortion, reliably reverting to its initial form. Additionally, its high fatigue resistance guarantees durability even under continuous stress in challenging medical environments.Plus, the biocompatibility of nitinol ensures safe long-term use inside the human body, with consistent batch-to-batch material quality critical for device safety and performance.
Advanced Black Oxidized Surface Finish for Medical Applications
Our proprietary black oxidized surface treatment forms a uniform, durable oxide layer directly on the nitinol wire. This finish enhances corrosion resistance and reduces nickel ion release, significantly improving biocompatibility. The smooth, lubricious surface minimizes friction during device navigation through delicate tissues and catheters. Moreover, the distinctive black color improves visibility under medical imaging, enabling precise device placement without additional coatings.
Ultra-Precise Diameter Control
Featuring a tightly controlled diameter of 0.055mm with ±0.001mm tolerance, this microfilament supports the exacting dimensional requirements of micro-medical devices. This precision ensures consistent mechanical properties and seamless assembly, essential for the performance of micro-guidewires, catheters, and minimally invasive implants.
