SAE-AISI S2 Steel vs. Grade CU5MCuC Nickel

SAE-AISI S2 steel belongs to the iron alloys classification, while grade CU5MCuC nickel belongs to the nickel alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 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 S2 steel and the bottom bar is grade CU5MCuC nickel.
