AISI 310MoLN Stainless Steel vs. C71000 Copper-nickel

AISI 310MoLN stainless steel belongs to the iron alloys classification, while C71000 copper-nickel belongs to the copper alloys. They have a modest 22% 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 (11, in this case) are not shown.

For each property being compared, the top bar is AISI 310MoLN stainless steel and the bottom bar is C71000 copper-nickel.
