Grade M30C Nickel vs. C18900 Copper

Grade M30C nickel belongs to the nickel alloys classification, while C18900 copper belongs to the copper 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 (2, in this case) are not shown.

For each property being compared, the top bar is grade M30C nickel and the bottom bar is C18900 copper.
