L605 (Cobalt-Chromium Alloy) Precision Micro-Tubing & Components for Medical Devices

L605 (UNS R30605 / ASTM F90) is a high-performance Cobalt-Chromium-Tungsten-Nickel superalloy widely utilized for critical medical applications, most notably cardiovascular and endovascular stents. Combining high yield strength, exceptional fatigue resistance, and proven biocompatibility, it enables medical device engineers to design ultra-thin-walled structural implants without compromising mechanical integrity.

Key Material Advantages

High Radiopacity: Containing approximately 15% Tungsten, L605 offers exceptional X-ray visibility under fluoroscopy, ensuring precise placement of stents and micro-implants during interventional procedures.

Ultra-Thin Wall Capability with High Strength: The high modulus of elasticity and tensile strength allow for structural miniaturization, enabling thinner stent struts that improve endovascular healing and reduce vessel trauma.

Biocompatibility & Corrosion Resistance: Excellent long-term clinical safety profile, non-magnetic properties, and strong resistance to body fluid corrosion.
