A380.0 Aluminum vs. EN AC-44000 Aluminum

Both A380.0 aluminum and EN AC-44000 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 94% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is A380.0 aluminum and the bottom bar is EN AC-44000 aluminum.
