  • Patent number: 6203632
    Abstract: The invention relates to iron-chromium aluminum metal foil which is resistant to high-temperature oxidation. Said metal foil is produced by hot-dip aluminizing an iron-chromium support band with an aluminum-silicon alloy. The foil has the following composition in weight percent: 18-25% Cr. 4-10% Al, 0.03-0.08% Y, max. 0.01% Ti, 0.01-0.05% Zr, 0.01-0.05% Hf, 0.5-1.5% Si. It also contains residual iron and impurities resulting from the method of production. The total aluminum content of the coated metal foil is at least 7% near the surface and not less than 3% further inside.
