EN 1.4005 Stainless Steel vs. Grade CU5MCuC Nickel

EN 1.4005 stainless steel belongs to the iron alloys classification, while grade CU5MCuC nickel belongs to the nickel alloys. They have 44% of their average alloy composition in common. 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 EN 1.4005 stainless steel and the bottom bar is grade CU5MCuC nickel.
