C37100 Brass vs. ZA-8

C37100 brass belongs to the copper alloys classification, while ZA-8 belongs to the zinc alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is C37100 brass and the bottom bar is ZA-8.
