C36200 Brass vs. ZA-12

C36200 brass belongs to the copper alloys classification, while ZA-12 belongs to the zinc alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is C36200 brass and the bottom bar is ZA-12.
