Overview of High-Performance Cobalt Chromium Tubes
Engineered from premium medical-grade cobalt chromium alloys (L605 / MP35N equivalents), these seamless precision tubes are the preferred choice for next-generation interventional device components. Designed specifically for demanding minimally invasive applications, our CoCr tubing combines ultra-high tensile strength, fatigue resistance, and excellent fluoroscopic visibility to enable thinner struts, superior deliverability, and long-term performance in vascular scaffolding, catheter systems, and endovascular delivery devices.
Features of Cobalt Chromium Interventional Device Tubing Components
Exceptional Mechanical Strength & Fatigue Resistance – High tensile strength (900–1400 MPa) allows ultra-thin walls while maintaining radial force and durability under cyclic loading in stents and hypotubes.
Superior Corrosion Resistance & Biocompatibility – Chromium oxide passive layer ensures long-term stability in physiological environments; fully biocompatible for permanent implants.
High Radiopacity – Superior X-ray visibility during fluoroscopy-guided minimally invasive procedures, reducing procedure time and improving precision.
Precision Tolerances & Surface Finish – Tight dimensional control (±0.001" possible), smooth electropolished surfaces, and kink-resistant performance for catheter components and guidewires.
MRI Compatibility & Thin-Wall Capability – Minimal imaging artifacts; supports ultra-thin struts for better crossing profiles in complex interventional cardiology and neurovascular interventions.
Custom Manufacturing Ready – Laser-cuttable, balloon-expandable, and compatible with drug-eluting coatings for advanced endovascular devices.
Applications of CoCr Tubes in Minimally Invasive Interventional
Cardiovascular Interventions – Coronary and peripheral balloon-expandable stents, stent delivery systems, and structural heart components.
Neurovascular & Peripheral Interventions – Guidewires, microcatheters, hypotubes, and embolic protection devices requiring high pushability and torque control.
Endovascular Delivery Systems – Thin-wall tubing for balloon catheters, introducer sheaths, and transcatheter valve delivery systems.
Interventional Radiology & Minimally Invasive Surgery – Precision components for vascular access, atherectomy devices, and chronic total occlusion (CTO) crossing tools.

FAQs on CoCr Tubing for Interventional Devices
Q1: What alloys are used in these high-performance cobalt chromium tubes?
A: Primarily medical-grade L605 (Co-Cr-W-Ni) and MP35N (Co-Cr-Ni-Mo) alloys meeting ASTM F90, ASTM F562, and ISO 5832-4 standards.
Q2: Why choose CoCr over stainless steel or nitinol for interventional components?
A: CoCr offers higher radial strength, better radiopacity, and superior fatigue life in thin-wall designs, enabling lower profile devices with reduced recoil—critical for minimally invasive stent delivery and catheter performance.
Q3: Are these tubes suitable for laser cutting into stents?
A: Yes – seamless drawn tubing is optimized for laser cutting into bare-metal stents (BMS) and drug-eluting stents (DES) with excellent edge quality and surface finish.
Q4: What wall thickness and diameter ranges are available?
A: Micro to standard sizes: OD 0.3–25 mm, wall thickness 0.05–2 mm (custom ultra-thin options down to 0.0005" available for high-performance interventional applications).
Q5: Do the tubes support MRI and fluoroscopy procedures?
A: Excellent radiopacity under fluoroscopy and proven MRI compatibility with minimal artifacts, ideal for real-time image-guided minimally invasive interventions.
