  • Platinum-Iridium Alloy Tube

    • Platinum-iridium alloy tube is made from a high-quality blend of platinum (Pt) and iridium (Ir) in a 90/10 ratio (PtIr10). This chemical composition offers excellent biocompatibility, resistance to electrolytic corrosion, and radiopacity, making it an ideal choice for demanding medical environments.

    Widely used in the manufacturing of precision interventional devices, Platinum-iridium alloy tubes are commonly applied in neuroelectrodes, vascular intervention catheters, and other high-reliability implantable or diagnostic medical equipment. The alloy’s mechanical strength, chemical stability, and visibility under imaging systems (such as fluoroscopy) allow for safe and precise navigation within the human body.
