EN 1.5918 Steel vs. Grade CU5MCuC Nickel

EN 1.5918 steel belongs to the iron alloys classification, while grade CU5MCuC nickel belongs to the nickel alloys. They have a modest 34% 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 EN 1.5918 steel and the bottom bar is grade CU5MCuC nickel.
