Platinum/Rhodium Alloy Spooled Wire (Pt60/Rh40)

Platinum Rhodium Alloy Spooled Wire (Pt60/Rh40) combines high-temperature oxidation resistance, mechanical strength, and excellent electrical conductivity in a continuous, manageable wire format. The spooled configuration enables precise deployment in applications requiring extended lengths, such as thermocouple fabrication, high-temperature sensor assemblies, and custom heating elements. The Pt-Rh alloy’s stability under extreme thermal cycling makes it invaluable for aerospace instrumentation, industrial process monitoring, and catalyst electrode systems. Specific uses include long-run thermocouple leads, furnace atmosphere sensors, and conductive elements in emission control units. In research, the wire supports high-precision electrical testing, prototype thermoelectric devices, and experiments involving sustained high-temperature exposure. Its combination of noble alloy resilience and convenient spool handling ensures reliability in both advanced industrial processes and scientific investigation.
