SAE-AISI A4 Steel vs. N06045 Nickel

SAE-AISI A4 steel belongs to the iron alloys classification, while N06045 nickel belongs to the nickel alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI A4 steel and the bottom bar is N06045 nickel.
