C68400 Brass vs. Grade M30H Nickel

C68400 brass belongs to the copper alloys classification, while grade M30H nickel belongs to the nickel alloys. They have a modest 34% 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 C68400 brass and the bottom bar is grade M30H nickel.
