ALUMINUM ALLOY FOIL AND METHOD FOR PRODUCING SAME, MOLDED PACKAGING MATERIAL, SECONDARY CELL, AND MEDICAL DRUG CONTAINER

摘要

Provided is an aluminum alloy foil having good moldability. Provided is an aluminum alloy foil comprising 0.8 to 2.0 mass% of Fe, 0.05 to 0.2 mass% of Si, and 0.0025 to 0.2 mass% of Cu, with the remainder being Al and inevitable impurities. According to the aluminum alloy foil, cube orientation density is 5 or greater and R orientation density is 50 or less in the crystal orientation of the aluminum alloy foil surface. The average crystal grain size of the aluminum alloy foil is 7 to 20 µm.
