Composition: Pt 90/Rh 10
Form: Foil (Light Tight)
Material: Platinum/Rhodium
Commodity: Precious Metals
Light Tight:
Light Tight
Platinum Rhodium Alloy Foil Light Tight (Pt90/Rh10) offers exceptional corrosion resistance, thermal stability, and mechanical integrity in a fully opaque sheet free of pinholes, preventing any external light penetration. The high platinum content enhances chemical inertness, while rhodium improves hardness and oxidation resistance, making it suitable for aerospace heat shields, optical barriers, and high-purity furnace components. Applications include precision thermocouple sheaths for ultra-high-temperature measurements, catalyst substrates in emission control systems, and light-exclusion barriers in sensitive spectroscopic setups. In research, this foil is employed in optical device isolation, photonic experiment chambers, and high-vacuum thermal testing. The flawless light-tight structure, combined with noble alloy performance, ensures reliability in environments demanding both optical control and long-term material stability.
