Grade M30C Nickel vs. C23400 Brass

Grade M30C nickel belongs to the nickel alloys classification, while C23400 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 22 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is grade M30C nickel and the bottom bar is C23400 brass.
