Overview of ASTM F562 Cobalt Chromium Tube
Our ASTM F562 cobalt chromium tube (MP35N UNS R30035) is a premium multiphase cobalt-based superalloy seamless tubing specifically designed for high-performance interventional medical devices and minimally invasive instruments. Conforming to ASTM F562 standards, this Co-Ni-Cr-Mo alloy delivers ultra-high tensile strength (up to 260-300 ksi), outstanding corrosion resistance in physiological environments, non-magnetic properties, and proven biocompatibility for long-term implantation contact.
Ideal for precision hypotube manufacturing, catheter shafts, guide catheter components, and structural supports in percutaneous coronary intervention (PCI), peripheral vascular procedures, and neurovascular applications, this tubing enables thinner walls, smaller profiles, and enhanced pushability/torqueability while maintaining durability under cyclic loading.
Features of MP35N Cobalt Chromium Tube for Minimally Invasive
Ultra-High Strength & Fatigue Resistance — Exceptional tensile strength and endurance limit for reliable performance in dynamic interventional environments.
Superior Corrosion Resistance — Outstanding resistance to pitting, crevice corrosion, and bodily fluids, ensuring longevity in cardiovascular and minimally invasive procedures.
Excellent Biocompatibility — ASTM F562-compliant for surgical implant-grade applications with minimal inflammatory response.
Non-Magnetic Properties — MRI conditional/compatible for advanced imaging during and post-procedure.
Precision Dimensional Control — Seamless drawn micro-tubing with tight tolerances for hypotube, catheter, and guidewire components.
High Radiopacity — Enhanced visibility under fluoroscopy for precise navigation in interventional cardiology.
Customizable Sizes — Available in micro to small diameters with thin walls for low-profile minimally invasive device designs.
Applications of Interventional & Minimally Invasive Devices
Our CoCr alloy tubing is specifically designed for advanced interventional cardiology and minimally invasive surgical instruments, including:
Cardiovascular stent manufacturing — Hypotubing base material for drug-eluting stents and bare-metal stents requiring high radial strength.
Guidewire and catheter shafts — Core tubing for coronary guidewires, peripheral guidewires, and diagnostic/therapeutic catheters.
Endovascular delivery systems — Low-profile components for balloon catheters, sheaths, and valve delivery devices.
Neurovascular and peripheral interventions — Precision tubing for micro-catheters and embolization devices.
Other minimally invasive tools — Structural elements in orthopedic navigation instruments or hybrid interventional devices.
