Aluminum alloy foil, a laminated body, the manufacturing method of aluminum alloy foil, and the manufacturing method of a laminated body

摘要

The aluminum alloy foil 1 is an aluminum alloy foil which has the 1st surface 1A. Aluminum alloy foil 1 contains aluminum, silicon, 0.4 mass % or more and 1.75 mass % or less manganese, 0.02 mass % or more and 0.08 mass % or less iron, 0.00001 mass % or more and 0.03 mass % or less zinc; 0.00001 mass % or more and 0.02 mass % or less copper and 0.00001 mass % or more and 0.01 mass % or less magnesium are included. Aluminum alloy foil 1 WHEREIN: The sum total of content of a silicon and iron is 0.1 mass % or less. In the aluminum alloy foil 1, the ratio of the mass of manganese with respect to the total mass of silicon and iron is 7.0 or more. On the 1st surface 1A, the area ratio of the 2nd phase particle|grains with a circle equivalent diameter of 1.5 micrometers or more is 0.1 % or less. The electrical resistivity is 3.0 μΩcm or more and 5.0 μΩcm or less.
