CC383H Copper-nickel vs. ACI-ASTM CN3MN Steel

CC383H copper-nickel belongs to the copper alloys classification, while ACI-ASTM CN3MN steel belongs to the iron alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is CC383H copper-nickel and the bottom bar is ACI-ASTM CN3MN steel.
