Overview of Medical Grade Cobalt Chromium CoCr Tubing
Our Medical Grade Cobalt Chromium CoCr Tubing is precision-engineered for demanding interventional devices and minimally invasive instruments in cardiovascular and endovascular applications. Manufactured from high-performance CoCr alloys (conforming to standards such as ASTM F90 / F562 equivalents), this hypotubing delivers superior mechanical properties including high tensile strength, excellent fatigue resistance, and minimal recoil—critical for balloon expandable stents, guidewire cores, catheter shafts, and other minimally invasive interventional tools.
With outstanding corrosion resistance in physiological environments and proven biocompatibility, CoCr tubing ensures long-term safety and reliability in interventional cardiology procedures. Its high radiopacity enhances fluoroscopic visibility during complex endovascular interventions, while ultra-thin wall capabilities support low-profile delivery systems for enhanced patient outcomes.
Ideal for OEMs developing next-generation vascular interventional devices, this CoCr medical tubing combines durability, precision tolerances, and MRI conditional compatibility where required.

FAQs on CoCr Tubing for Interventional Devices
Q: What makes Cobalt Chromium (CoCr) tubing superior for interventional devices compared to stainless steel?
A: CoCr alloy offers higher strength-to-weight ratio, better corrosion resistance, higher radiopacity, and improved fatigue performance—ideal for thinner struts in minimally invasive stents and catheter tubing while maintaining durability.
Q: Is this CoCr tubing biocompatible and suitable for long-term implantation?
A: Yes, medical-grade CoCr materials have an extensive clinical history in cardiovascular stents, heart valves, and implants, with excellent biocompatibility and low thrombosis risk per FDA and ISO standards.
Q: What standards does your CoCr tubing comply with?
A: Typically aligned with ASTM F90, F562, or equivalent medical-grade specifications for cobalt-chromium alloy tubing in interventional applications.
Q: Can the tubing be customized for specific interventional catheter or stent designs?
A: Absolutely—custom OD, ID, wall thickness, annealing, surface finish (e.g., electropolished), and lengths are available to optimize pushability, trackability, and torque transmission in minimally invasive devices.
Q: Is CoCr tubing MRI safe or conditional?
A: Most CoCr interventional tubing is MRI conditional (non-ferromagnetic); confirm specific device labeling for field strength limits.
