Platinum Spooled Wire

Designed for high-performance environments, our Platinum Spooled Wire delivers exceptional purity, consistency, and reliability - ideal for scientific, industrial, and biomedical use. Produced from up to 99.998% pure platinum with tight dimensional tolerances, it's built for advanced R&D, emerging technologies, and precision systems. Offered in diameters from 0.01 mm to 1 mm and multiple tempers, it integrates easily into assemblies where precision and repeatability matter. Platinum’s chemical inertness ensures corrosion resistance in aggressive environments, while its high melting point and thermal stability support reliable performance under extreme conditions. A predictable resistivity profile makes it ideal for temperature sensing, and superior ductility allows cold-working into ultra-fine or robust conductors - available in lengths up to 285 meters. With catalytic activity, electrochemical stability, and biocompatibility, platinum remains the top choice for fuel cells, sensors, and implantable devices.
