CC383H Copper-nickel vs. N08020 Stainless Steel

CC383H copper-nickel belongs to the copper alloys classification, while N08020 stainless steel belongs to the iron alloys. They have a modest 36% 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 (5, in this case) are not shown.

For each property being compared, the top bar is CC383H copper-nickel and the bottom bar is N08020 stainless steel.
