Grade M30H Nickel vs. C19400 Copper

Grade M30H nickel belongs to the nickel alloys classification, while C19400 copper belongs to the copper alloys. They have a modest 32% 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 grade M30H nickel and the bottom bar is C19400 copper.
