Commodity: Precious Metals Material: Platinum/Rhodium Form: Foil (Light Tight) Composition: Pt 60/Rh 40 Temper: As Rolled Thickness: 0.125mm Coating: Uncoated Opacity: Light Tight Surface Finish: Standard
Platinum Rhodium Alloy Foil Light Tight (Pt60/Rh40) combines exceptional high-temperature oxidation resistance, mechanical stability, and electrical conductivity in a fully opaque sheet free of pinholes, ensuring no external light transmission for sensitive optical or thermal systems. The Pt-Rh alloy’s superior resistance to chemical attack and creep deformation under extreme heat makes it valuable in aerospace thermal shielding, precision furnace linings, and high-vacuum environments. Applications include thermocouple sheathing in extreme-temperature calibration, catalyst supports for emission control, and reflective barriers in aerospace optical systems. In research, the light-tight foil supports spectroscopy setups, photonic device isolation, and controlled-environment optical experiments. This combination of a flawless, pinhole-free surface with the alloy’s mechanical and chemical durability ensures reliable performance in demanding scientific and industrial contexts.
