4004 Aluminum vs. EN AC-44500 Aluminum

Both 4004 aluminum and EN AC-44500 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 97% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is 4004 aluminum and the bottom bar is EN AC-44500 aluminum.
