EN 1.4588 Stainless Steel vs. CC383H Copper-nickel

EN 1.4588 stainless steel belongs to the iron alloys classification, while CC383H copper-nickel belongs to the copper alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is EN 1.4588 stainless steel and the bottom bar is CC383H copper-nickel.
