A1-Mg-Si based alloy sheet

Abstract

The present invention provides an Al—Mg—Si based alloy sheet whose press-formability (particularly, deep-drawing formability, stretch-formability and bendability) is made higher than conventional Al—Mg—Si based alloy sheets of JIS 6000 series. For texture of the Al—Mg—Si based alloy sheet, orientation density of at least Cube orientation is controlled in accordance with a sort of press forming, so that press-formability improved to match with the press forming is provided. For example, to improve deep-drawing formability of an Al—Mg—Si based alloy sheet, the ratio of orientation density of Goss orientation to the orientation density of the Cube orientation (Goss/Cube) is set to 0.3 or less, and a grain size is set to 80 μm or less.
