B443.0 Aluminum vs. 383.0 Aluminum

Both B443.0 aluminum and 383.0 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 90% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is B443.0 aluminum and the bottom bar is 383.0 aluminum.
