Monel 400 vs. CR008A Copper

Monel 400 belongs to the nickel alloys classification, while CR008A 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 (4, in this case) are not shown.

For each property being compared, the top bar is Monel 400 and the bottom bar is CR008A copper.
