ALUMINUM ALLOY FOIL

摘要

An aluminum alloy foil formed container is provided which is formed of a aluminum alloy foil single body having at least a specified electric specific resistance, is excellent in formability and corrosion resistance, and is suitable for cooking by an electromagnetic cooker. Molten aluminum alloy is cast to a thickness of up to 10mm at a cooling rate of at least 100°C /second, then the cast product is cold-rolled to a thickness of 50-300µm, then the rolled product is annealed at at least 300°C for a heating retaining time of up to 10 minutes to form an aluminum alloy foil, 50-200µm in thickness and at least 6.0 µOcm in electric specific resistance, and it is press-formed to obtain an aluminum alloy foil formed container (10) having a bottom wall (11), a peripheral wall (12) and a flange (13). This container (10) is excellent in formability (especially pinhole resistance) and corrosion resistance, and has an electric resistance suitable for cooking by an electromagnetic cooker.
