Z13004 Zinc vs. CC763S Brass

Z13004 zinc belongs to the zinc alloys classification, while CC763S brass belongs to the copper alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is Z13004 zinc and the bottom bar is CC763S brass.
