SAE-AISI 1078 Steel vs. N09777 Nickel

SAE-AISI 1078 steel belongs to the iron alloys classification, while N09777 nickel belongs to the nickel alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 SAE-AISI 1078 steel and the bottom bar is N09777 nickel.
