Grade CX2MW Nickel vs. CC382H Copper-nickel

Grade CX2MW nickel belongs to the nickel alloys classification, while CC382H copper-nickel belongs to the copper alloys. They have a modest 34% 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 grade CX2MW nickel and the bottom bar is CC382H copper-nickel.
