Overview of Cobalt Chrome Tubing
Our ISO certified medical cobalt-chromium alloy tubing (ASTM F90, UNS R30605, also known as L605 or Haynes 25 equivalent) is engineered specifically for demanding implantable medical applications, with primary use in coronary stent manufacturing and other cardiovascular stent platforms.
This premium CoCr L605 tubing offers exceptional mechanical properties, including high tensile strength, excellent radial force, minimal recoil, and superior corrosion resistance in physiological environments. Its high tungsten content provides outstanding radiopacity for precise imaging during stent deployment and follow-up procedures.
Widely adopted in drug-eluting stents (DES) and bare metal stents (BMS), this medical grade cobalt chrome alloy enables thinner strut designs without compromising structural integrity—reducing vessel trauma and improving long-term patency in balloon-expandable stent applications.
Fully compliant with ASTM F90 standards for surgical implant applications, our precision-drawn tubing ensures consistent quality, biocompatibility, and performance for next-generation implantable cardiovascular devices.
Features of Cobalt Chromium Alloy Tubes
Superior High Radial Strength & Low Recoil: Twice the strength of 316L stainless steel at equivalent ductility, delivering radial force up to 1.1 bar even in ultra-thin wall configurations for reliable vessel support.
Excellent Radiopacity for Fluoroscopic Precision: High-density tungsten (14–16%) ensures superior visibility under X-ray, critical for accurate placement of coronary vascular stents.
Outstanding Fatigue Resistance in Thin-Walled CoCr Tubing: Proven high-cycle fatigue performance specifically engineered for thin-strut balloon-expandable stents under millions of cardiac cycles.
Premium Biocompatibility & Corrosion Resistance: ASTM F90 compliant cobalt chromium alloy tubing forms a stable passive chromium oxide layer, ensuring long-term hemocompatibility in implantable medical devices.
Non-Magnetic & MRI Compatible: Fully non-magnetic in all conditions, allowing safe post-implantation imaging.
Precision Seamless Tubing for Laser Cutting: Tight tolerance, defect-free medical-grade tubing optimized for high-precision laser micromachining into complex stent geometries.
Ultra-Thin Wall Capability: Supports strut thicknesses as low as 60 µm while preserving high radial strength and minimal dogboning.
