EN 2.4669 Nickel vs. CC381H Copper-nickel

EN 2.4669 nickel belongs to the nickel alloys classification, while CC381H copper-nickel belongs to the copper 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 (5, in this case) are not shown.

For each property being compared, the top bar is EN 2.4669 nickel and the bottom bar is CC381H copper-nickel.
