ALUMINUM ALLOY SHEET FOR BLOW MOLDING AND PRODUCTION METHOD THEREFOR

摘要

Provided is an aluminum alloy sheet for blow molding that contains 0.3-1.8 mass% of Mg, 0.6-1.6 mass% of Si, and 0.2-1.2 mass% of Mn. With regards to at least one surface of the aluminum alloy sheet for blow molding, when the proportion of an area in which the trough depth of the roughness curve is 0.3 µm or more is designated as X and the yield stress when the aluminum alloy sheet for blow molding is deformed under predetermined conditions is designated as Y, the relational expressions 0.10 <= X and Y >= -8.0X + 10.8 are satisfied.
