C76200 Nickel Silver vs. ZA-27

C76200 nickel silver belongs to the copper alloys classification, while ZA-27 belongs to the zinc alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is C76200 nickel silver and the bottom bar is ZA-27.
