More info

Platinum Rhodium (PtRh) Wire is a durable, high-performance alloy wire made from platinum and rhodium. It’s highly effective in applications requiring precision and stability, such as in high-temperature environments, sensors, and industrial equipment. Its resistance to oxidation and thermal stress ensures reliable long-term performance even in the harshest conditions. The wire is also suitable for use in fine electrical components and high-performance instruments. This alloy is good for electrical contacts, precision tools, and high-heat use. Heeger Materials provides Platinum-Rhodium Wire in various gauges and lengths, and you can customize them to meet your specific requirements.

Platinum Rhodium Wire is commonly used as thermocouple wires to make high-temperature thermocouples, capable of measuring and controlling temperatures in the range of 0-1800°C. The common types include Type B, Type R, and Type S.
