4145 Aluminum vs. A413.0 Aluminum

Both 4145 aluminum and A413.0 aluminum are aluminum alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 96% 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 4145 aluminum and the bottom bar is A413.0 aluminum.
