Abstract
An aluminum alloy sheet for a magnetic disk, a blank, and a substrate which are excellent in the proof stress and Young's modulus and in which the occurrence of cracks during rolling is prevented are provided. The aluminum alloy sheet for a magnetic disk, the blank, and the substrate contain: 2.1 mass% or more and 4.8 mass% or less of Mg; 1.00 mass% or less of Cu; 0.01 mass% or more and 0.30 mass% or less of Cr; 0.20 mass% or less of Si; and one or more of 0.10 mass% or more and 1.70 mass% or less of Fe, 0.06 mass% or more and 1.50 mass% or less of Mn, and 0.0001 mass% or more and 2.70 mass% or less of Ni, with the remainder being Al and impurities, in which the total content of Fe, Mn, Ni, and Cr is 1.05 mass% or more and 2.40 mass% or less, and a relationship of the content of Mg (mass%) < -2.75 the total content (mass%) + 8.8 is satisfied.
