Monel R-405 vs. CC750S Brass

Monel R-405 belongs to the nickel alloys classification, while CC750S brass belongs to the copper 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 (4, in this case) are not shown.

For each property being compared, the top bar is Monel R-405 and the bottom bar is CC750S brass.
