Formula: Pt 60/Rh 40
Form: Foil/Film/Sheet
Material: Platinum/Rhodium
Commodity: Precious Metals
Temper:
As Rolled
Thickness:
0.125mm
Platinum Rhodium Alloy Foil (Pt60/Rh40) delivers high-temperature oxidation resistance, chemical durability, and electrical conductivity in a thin, flexible sheet form, enabling precision integration into extreme-environment systems. The Pt-Rh composition resists creep and maintains mechanical integrity under prolonged heat exposure, making it valuable in aerospace, catalysis, and analytical instrumentation. Applications include thermocouple element protection, catalyst supports for emission control, and reflective barriers in high-vacuum chambers. In research, this foil is used for microfabricated electrode substrates, high-temperature reaction studies, and thermal interface layers. Its combination of thin-section adaptability with noble alloy resilience ensures consistent performance in both demanding industrial operations and advanced scientific experiments.
