ZA-8 vs. C46500 Brass

ZA-8 belongs to the zinc alloys classification, while C46500 brass belongs to the copper alloys. They have a modest 39% 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 (7, in this case) are not shown.

For each property being compared, the top bar is ZA-8 and the bottom bar is C46500 brass.
