Type 2 Magnetic Alloy vs. Grade M30H Nickel

Type 2 magnetic alloy belongs to the iron alloys classification, while grade M30H nickel belongs to the nickel alloys. They have 51% of their average alloy composition in common. There are 25 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 2 magnetic alloy and the bottom bar is grade M30H nickel.
