CR021A Copper vs. Monel 400
CR021A copper belongs to the copper alloys classification, while Monel 400 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 (4, in this case) are not shown.
For each property being compared, the top bar is CR021A copper and the bottom bar is Monel 400.
