Overview of Medical Grade Platinum Iridium (Pt90/10) Wire
Our medical grade platinum iridium (Pt90/10) wire is a premium precious metal alloy specifically developed for high-performance interventional guidewires and other minimally invasive medical devices. Composed of 90% platinum and 10% iridium, this alloy combines platinum’s excellent ductility and biocompatibility with iridium’s enhanced hardness, strength, and radiopacity.
The result is a material that offers outstanding visibility under fluoroscopy, reliable navigation through tortuous vessels, and long-term durability in dynamic vascular environments. Ideal for manufacturers of guidewires used in interventional cardiology, radiology, and neurology, this Pt/Ir wire meets stringent medical standards (including ASTM B684) and is FDA-approved for internal use.
