Monel R-405 vs. CR007A Copper

Monel R-405 belongs to the nickel alloys classification, while CR007A copper belongs to the copper 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 (3, in this case) are not shown.

For each property being compared, the top bar is Monel R-405 and the bottom bar is CR007A copper.
