5182 Aluminum vs. ZA-27

5182 aluminum belongs to the aluminum alloys classification, while ZA-27 belongs to the zinc alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is 5182 aluminum and the bottom bar is ZA-27.
