324.0-F Aluminum vs. 5251-F Aluminum

Both 324.0-F aluminum and 5251-F 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 324.0-F aluminum and the bottom bar is 5251-F aluminum.
