Grade CX2M Nickel vs. ACI-ASTM CB7Cu-2 Steel

Grade CX2M nickel belongs to the nickel alloys classification, while ACI-ASTM CB7Cu-2 steel belongs to the iron alloys. They have a modest 21% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 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 grade CX2M nickel and the bottom bar is ACI-ASTM CB7Cu-2 steel.
