C71500 Copper-nickel vs. 50Cr-50Ni Alloy

C71500 copper-nickel belongs to the copper alloys classification, while 50Cr-50Ni alloy belongs to the otherwise unclassified metals. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is C71500 copper-nickel and the bottom bar is 50Cr-50Ni alloy.
