Grade M30H Nickel vs. C21000 Brass

Grade M30H nickel belongs to the nickel alloys classification, while C21000 brass 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 (4, in this case) are not shown.

For each property being compared, the top bar is grade M30H nickel and the bottom bar is C21000 brass.
