AWS E219 vs. Type 3 Magnetic Alloy
AWS E219 belongs to the iron alloys classification, while Type 3 magnetic alloy belongs to the nickel alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is AWS E219 and the bottom bar is Type 3 magnetic alloy.
