Type 3 Magnetic Alloy vs. C72200 Copper-nickel
Type 3 magnetic alloy belongs to the nickel alloys classification, while C72200 copper-nickel belongs to the copper alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is Type 3 magnetic alloy and the bottom bar is C72200 copper-nickel.
