Type 2 Magnetic Alloy vs. C71500 Copper-nickel

Type 2 magnetic alloy belongs to the iron alloys classification, while C71500 copper-nickel belongs to the copper alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is Type 2 magnetic alloy and the bottom bar is C71500 copper-nickel.
