380.0 Aluminum vs. A380.0 Aluminum

Both 380.0 aluminum and A380.0 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. Their average alloy composition is basically identical. There are 31 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 380.0 aluminum and the bottom bar is A380.0 aluminum.
