C97800 Nickel Silver vs. Grade CY40 Nickel

C97800 nickel silver belongs to the copper alloys classification, while grade CY40 nickel belongs to the nickel alloys. They have a modest 26% 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 C97800 nickel silver and the bottom bar is grade CY40 nickel.
