PtIr10 Platinum Iridium Wire 0.025mm Medical Electrode Wire 90%Pt 10%Ir Alloy
PtIr10 Platinum Iridium Wire 0.025mm for Medical Electrode Applications
Product Overview
PtIr10 platinum iridium wire is a precision-drawn fine wire with a nominal composition of 90% platinum and 10% iridium. At 0.025 mm (25 µm) diameter, this wire combines the corrosion resistance and electrical stability of platinum with the additional strength and spring-back properties provided by iridium. It is widely specified in the manufacture of medical electrodes, guidewires, sensor contacts and other precision components.
Key Features
