C96300 Copper-nickel vs. 50Cr-50Ni-Cb Alloy

C96300 copper-nickel belongs to the copper alloys classification, while 50Cr-50Ni-Cb alloy belongs to the otherwise unclassified metals. They have a modest 22% 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 (8, in this case) are not shown.

For each property being compared, the top bar is C96300 copper-nickel and the bottom bar is 50Cr-50Ni-Cb alloy.
