EN AC-45000 Aluminum vs. 238.0 Aluminum

Both EN AC-45000 aluminum and 238.0 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 93% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is EN AC-45000 aluminum and the bottom bar is 238.0 aluminum.
