EN 2.4952 Nickel vs. C71000 Copper-nickel

EN 2.4952 nickel belongs to the nickel alloys classification, while C71000 copper-nickel belongs to the copper alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is EN 2.4952 nickel and the bottom bar is C71000 copper-nickel.
