C91700 Bronze vs. Grade M30H Nickel

C91700 bronze belongs to the copper alloys classification, while grade M30H nickel belongs to the nickel 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 (2, in this case) are not shown.

For each property being compared, the top bar is C91700 bronze and the bottom bar is grade M30H nickel.
