ACI-ASTM CB7Cu-2 Steel vs. EN 2.4669 Nickel

ACI-ASTM CB7Cu-2 steel belongs to the iron alloys classification, while EN 2.4669 nickel belongs to the nickel alloys. They have a modest 28% 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 (6, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CB7Cu-2 steel and the bottom bar is EN 2.4669 nickel.
