EN AC-47100 Aluminum vs. 4004 Aluminum

Both EN AC-47100 aluminum and 4004 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 96% 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 EN AC-47100 aluminum and the bottom bar is 4004 aluminum.
