Overview of High Purity Seamless Cobalt Chromium Tube
Our high purity seamless cobalt chromium tube is engineered specifically for demanding implantable cardiac devices and cardiovascular implants. Manufactured from premium medical-grade CoCr alloy (commonly L605 equivalent), this seamless tubing delivers unmatched biocompatibility, corrosion resistance and mechanical performance essential for long-term implantation in the human body.
Unlike traditional stainless steel, cobalt chromium seamless tubing enables thinner walls with superior radial strength, enhanced fatigue resistance under pulsatile cardiac loading, and excellent radiopacity for precise fluoroscopic placement. Ideal raw material for laser-cutting into coronary stents, pacemaker leads, heart valve frames and other implantable medical applications requiring high reliability and endothelial compatibility.
Certified to rigorous medical standards, our seamless CoCr tubing minimizes surface defects, reduces thrombogenicity risk, and supports advanced biofunctionalized cardiovascular devices. Trust this high-performance CoCr alloy tube to elevate safety and durability in next-generation implantable cardiac solutions.
Features of Seamless Cobalt Chromium Tubing for Cardiac Implants
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.
Applications in Implantable Cardiac & Cardiovascular Devices
Our high purity seamless cobalt chromium tube serves as the foundational material in various implantable medical applications, particularly:
Coronary & Peripheral Stents – Bare-metal and drug-eluting platforms requiring high radial force and flexibility.
Pacemaker & ICD Leads – Tubing for electrodes and conductor components demanding fatigue endurance.
Heart Valve Frames & Components – Structural elements in transcatheter aortic valves (TAVI/TAVR) and other prosthetic valves.
Cardiovascular Implants – Vascular grafts, septal occluders and other long-term cardiac support devices.
Neurovascular & Peripheral Devices – Where biocompatibility and strength are critical for chronic implantation.
