ACI-ASTM CK35MN Steel vs. C72150 Copper-nickel

ACI-ASTM CK35MN steel belongs to the iron alloys classification, while C72150 copper-nickel belongs to the copper alloys. They have a modest 22% 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 (4, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CK35MN steel and the bottom bar is C72150 copper-nickel.
