Abstract:
1. An Al—Mg—Si alloy sheet, comprising Mg in an amount of 0.4 to 1.9 mass % and Si in an amount of 0.2 to 1.9 mass %, wherein respective textures of Cube orientation, CR orientation, RW orientation, Goss orientation, Brass orientation, S orientation, Cu orientation, and PP orientation satisfy the conditions of the following expression (1): (where [x] denotes the standard deviation (%) of the area ratio of an orientation x in a sheet cross section every 500 μm along the sheet width direction); and wherein the Al—Mg—Si alloy sheet is produced by a process comprising cold rolling an intermediate material, which comprises Mg in an amount of 0.4 to 1.9 mass % and Si in an amount of 0.2 to 1.9 mass %, which is in shape of a sheet, and in which the average value of the crystal sizes along the sheet thickness direction of textures of respective orientations is 50 μm or less.
