AISI 310 Stainless Steel Foil (Light Tight)

AISI 310 Stainless Steel Foil (Light Tight) is a high-chromium, high-nickel austenitic alloy designed for extreme-temperature stability, oxidation resistance, and complete exclusion of external light transmission through its pinhole-free structure. This unique light-tight quality makes it indispensable in optical, photonic, and electronic shielding applications where both structural and environmental protection are essential. Its combination of heat resistance up to ~1100 °C and corrosion resilience supports use in aerospace thermal management systems, catalyst carriers for emission control, and precision shielding for OLED and flexible display manufacturing. Specific applications include light-isolated sensor housings, high-purity furnace encapsulation, and optical calibration devices. In research, it enables controlled testing environments for light-sensitive materials, surface oxidation behavior studies, and thermal cycling performance evaluations. The synergy of light-tight integrity, high-temperature capability, and corrosion performance ensures its critical role in both advanced manufacturing and scientific innovation.
