Type 1 Magnetic Alloy vs. Type 4 Magnetic Alloy
Type 1 magnetic alloy belongs to the iron alloys classification, while Type 4 magnetic alloy belongs to the nickel alloys. They have 60% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is Type 1 magnetic alloy and the bottom bar is Type 4 magnetic alloy.
