The aluminum alloy board null mass which is superior in rijingumaku characteristic

摘要

PROBLEM TO BE SOLVED: To provide an Al-Mg-Si-based aluminum alloy sheet, wherein ridging marks upon press forming can be prevented even in the case forming conditions are made more severe.;SOLUTION: In the Al-Mg-Si-based aluminum alloy sheet having a specified composition, regarding the texture in the sheet width direction relatively in a relatively wide range, three of Goss orientation, Cube orientation and rotation Cube orientation, particularly, are suppressed by the average area ratio in the sheet width direction, and further, respective deviations in the respective orientations in the texture are suppressed as well. Thus, the ridging marks having a cycle of relatively large sheet surface ruggedness in the sheet width direction are suppressed.;COPYRIGHT: (C)2011,JPO&INPIT
