PROBLEM TO BE SOLVED: To obtain an Al-Mg-Si series aluminum alloy for forming in which ridging marks are suppressed. ;SOLUTION: In an Al-Mg-Si series alloy sheet contg., by weight, 0.2 to 1.0% Mg and 0.2 to 1.5% Si, as to the texture, the orientation distributed density in the Goss orientation is regulated to ≤3, the orientation distributed density in the PP orientation is regulated to ≤3, and the orientation distributed density in the Brass orientation is regulated to ≤3. As the alloy components, one or more kinds among, by weight, ≤1.0% Mn, ≤0.3% Cr, ≤1.0% Fe, ≤0.3% Zr, ≤0.3% V and 0.1% Ti by 0.01 to 1.5% in total and moreover one or ≥ two kinds among ≤1.0% Cu, ≤0.2% Ag, ≤1.0% Zn and ≤0.2% Sn by 0.01 to 1.5% in total may be contained.;COPYRIGHT: (C)1999,JPO
