Product Description
Shipping & Delivery
High-Purity Platinum–Rhodium Alloy Wire for Thermocouples & High-Temperature Applications
FrankLab supplies Platinum–Rhodium (Pt–Rh) alloy wire with ultra-high purity and tightly controlled composition, widely used in high-temperature thermocouples, precision temperature measurement, electrochemical research, and advanced materials applications.
Platinum–Rhodium alloys combine the chemical inertness of platinum with the enhanced mechanical strength and high-temperature stability of rhodium, making them the industry standard for Type S, Type R, and Type B thermocouples.
