C71500 Copper-nickel vs. EN 1.4606 Stainless Steel

C71500 copper-nickel belongs to the copper alloys classification, while EN 1.4606 stainless steel belongs to the iron alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is C71500 copper-nickel and the bottom bar is EN 1.4606 stainless steel.
