Grade CU5MCuC Nickel vs. SAE-AISI 1340 Steel

Grade CU5MCuC nickel belongs to the nickel alloys classification, while SAE-AISI 1340 steel belongs to the iron alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is grade CU5MCuC nickel and the bottom bar is SAE-AISI 1340 steel.
