Type 2 Magnetic Alloy vs. C71640 Copper-nickel

Type 2 magnetic alloy belongs to the iron alloys classification, while C71640 copper-nickel belongs to the copper alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is Type 2 magnetic alloy and the bottom bar is C71640 copper-nickel.
