AISI 334 Stainless Steel vs. CC382H Copper-nickel

AISI 334 stainless steel belongs to the iron alloys classification, while CC382H copper-nickel belongs to the copper alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is AISI 334 stainless steel and the bottom bar is CC382H copper-nickel.
