Type 3 Magnetic Alloy vs. ACI-ASTM CD3MWCuN Steel

Type 3 magnetic alloy belongs to the nickel alloys classification, while ACI-ASTM CD3MWCuN steel belongs to the iron alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 Type 3 magnetic alloy and the bottom bar is ACI-ASTM CD3MWCuN steel.
