C12900 Copper vs. Grade M35-2 Nickel

C12900 copper belongs to the copper alloys classification, while grade M35-2 nickel belongs to the nickel alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is C12900 copper and the bottom bar is grade M35-2 nickel.
