CC381H Copper-nickel vs. Grade CY40 Nickel

CC381H copper-nickel belongs to the copper alloys classification, while grade CY40 nickel belongs to the nickel alloys. They have a modest 32% 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 CC381H copper-nickel and the bottom bar is grade CY40 nickel.
