Grade CX2M Nickel vs. CC381H Copper-nickel

Grade CX2M nickel belongs to the nickel alloys classification, while CC381H copper-nickel belongs to the copper alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is grade CX2M nickel and the bottom bar is CC381H copper-nickel.
