Commercially Pure Zinc vs. C73100 Nickel Silver

Commercially pure zinc belongs to the zinc alloys classification, while C73100 nickel silver belongs to the copper alloys. They have a modest 20% 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 C73100 nickel silver.
