ALUMINUM ALLOY SHEET FOR BLOW MOLDING AND PRODUCTION METHOD THEREFOR

摘要

Provided is an aluminum alloy plate for blow molding comprising: 0.3% by mass or more and 1.8% by mass or less of Mg; 0.6% by mass or more and 1.6% by mass or less of Si; and 0.2% by mass or more and 1.2% by mass or less of Mn; wherein, in at least one surface of the aluminum alloy plate for blow molding, X and Y satisfy the following relations: 0.10≦X, and, Y≦−8.0X+10.8; wherein X represents the ratio of regions whose valley depth in a roughness curve is 0.3 μm or more; and Y represents the yield stress upon deformation of the aluminum alloy plate for blow molding under predetermined conditions.
