SAE-AISI 1018 Steel vs. Grade CU5MCuC Nickel
SAE-AISI 1018 steel belongs to the iron alloys classification, while grade CU5MCuC nickel belongs to the nickel 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 (8, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI 1018 steel and the bottom bar is grade CU5MCuC nickel.
