Abstract
This aluminum alloy sheet has increased BH properties under low-temperature short-time-period conditions after long-term room-temperature aging by means of causing aggregates of specific atoms to be contained having a large effect in BH properties, the distance between atoms being no greater than a set distance, and containing either Mg atoms or Si atoms measured by 3D atom probe field ion microscopy in a 6000 aluminum alloy sheet containing a specific amount of Mg and Si.
