C71580 Copper-nickel vs. Type 1 Magnetic Alloy
C71580 copper-nickel belongs to the copper alloys classification, while Type 1 magnetic alloy belongs to the iron alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 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 C71580 copper-nickel and the bottom bar is Type 1 magnetic alloy.
