CC763S Brass vs. ZA-27

CC763S brass belongs to the copper alloys classification, while ZA-27 belongs to the zinc alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is CC763S brass and the bottom bar is ZA-27.
