ACI-ASTM CD4MCu Steel vs. N07752 Nickel

ACI-ASTM CD4MCu steel belongs to the iron alloys classification, while N07752 nickel belongs to the nickel alloys. They have a modest 29% 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 CD4MCu steel and the bottom bar is N07752 nickel.
