C67400 Bronze vs. Commercially Pure Zinc

C67400 bronze belongs to the copper alloys classification, while commercially pure zinc belongs to the zinc alloys. They have a modest 36% 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 (2, in this case) are not shown.

For each property being compared, the top bar is C67400 bronze and the bottom bar is commercially pure zinc.
