ZA-27 vs. 1230A Aluminum

ZA-27 belongs to the zinc alloys classification, while 1230A aluminum belongs to the aluminum 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 ZA-27 and the bottom bar is 1230A aluminum.
