Type 3 Magnetic Alloy vs. Grade VDC Steel

Type 3 magnetic alloy belongs to the nickel alloys classification, while grade VDC steel belongs to the iron alloys. There are 22 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is Type 3 magnetic alloy and the bottom bar is grade VDC steel.
