C64800 Bronze vs. Grade M30H Nickel

C64800 bronze belongs to the copper alloys classification, while grade M30H nickel belongs to the nickel alloys. They have a modest 31% 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 C64800 bronze and the bottom bar is grade M30H nickel.
