ASTM B522 Class I vs. Type 4 Magnetic Alloy
ASTM B522 class I belongs to the otherwise unclassified metals classification, while Type 4 magnetic alloy belongs to the nickel alloys. There are 22 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is ASTM B522 class I and the bottom bar is Type 4 magnetic alloy.
