Z20301 Zinc vs. CC750S Brass

Z20301 zinc belongs to the zinc alloys classification, while CC750S brass belongs to the copper alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 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 Z20301 zinc and the bottom bar is CC750S brass.
