238.0 Aluminum vs. EN AC-46200 Aluminum

Both 238.0 aluminum and EN AC-46200 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 91% 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 238.0 aluminum and the bottom bar is EN AC-46200 aluminum.
