Grade N7M Nickel vs. Type 2 Magnetic Alloy

Grade N7M nickel belongs to the nickel alloys classification, while Type 2 magnetic alloy belongs to the iron alloys. They have 50% of their average alloy composition in common. There are 23 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 grade N7M nickel and the bottom bar is Type 2 magnetic alloy.
