CR012A Copper vs. Grade M30C Nickel

CR012A copper belongs to the copper alloys classification, while grade M30C 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 (1, in this case) are not shown.

For each property being compared, the top bar is CR012A copper and the bottom bar is grade M30C nickel.
