Al-Mg-Si-BASED ALLOY SHEET HAVING EXCELLENT SURFACE PROPERTY, PRODUCTION METHOD THEREFOR, AND PRODUCTION INTERMEDIATE MATERIAL THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an Al-Mg-Si-based alloy sheet in which the generation of ridging marks on press forming is remarkably suppressed, to provide a production method for obtaining such aluminum alloy sheet, and to provide a production intermediate material thereof. SOLUTION: The Al-Mg-Si-based alloy sheet has a prescribed componential composition, and in which each texture is present in a well balance. The alloy can efficiently be produced by the production method and the production intermediate material. COPYRIGHT: (C)2005,JPO&NCIPI
