50Cr-50Ni Alloy vs. C96400 Copper-nickel

50Cr-50Ni alloy belongs to the otherwise unclassified metals classification, while C96400 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 21 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni alloy and the bottom bar is C96400 copper-nickel.
