EN AC-51300 Aluminum vs. 308.0 Aluminum

Both EN AC-51300 aluminum and 308.0 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 89% 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 EN AC-51300 aluminum and the bottom bar is 308.0 aluminum.
