Type 3 Magnetic Alloy vs. C71580 Copper-nickel
Type 3 magnetic alloy belongs to the nickel alloys classification, while C71580 copper-nickel belongs to the copper alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is Type 3 magnetic alloy and the bottom bar is C71580 copper-nickel.
