ActiveFeCrAl foil for metallic honeycomb substrates
金属蜂窝载体用铁铬铝箔材
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for iron-chromium-aluminum (FeCrAl) foil used in metallic honeycomb substrates. It is applied in the manufacturing of catalytic converters for automotive exhaust systems, where the foil serves as a high-temperature-resistant, oxidation-resistant support structure for catalyst coatings. The standard ensures consistent foil thickness, surface quality, and mechanical properties critical for reliable performance in emission control applications.
