Commercially Pure Zinc vs. C87900 Brass

Commercially pure zinc belongs to the zinc alloys classification, while C87900 brass belongs to the copper alloys. They have a modest 33% 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 commercially pure zinc and the bottom bar is C87900 brass.
