CC762S Brass vs. Z20301 Zinc

CC762S brass belongs to the copper alloys classification, while Z20301 zinc belongs to the zinc alloys. They have a modest 25% 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 CC762S brass and the bottom bar is Z20301 zinc.
