Grade CU5MCuC Nickel vs. EN 1.6580 Steel
Grade CU5MCuC nickel belongs to the nickel alloys classification, while EN 1.6580 steel belongs to the iron alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is grade CU5MCuC nickel and the bottom bar is EN 1.6580 steel.
