Annealed ASTM B522 Class II vs. Annealed Type 4 Magnetic Alloy
Annealed ASTM B522 class II belongs to the otherwise unclassified metals classification, while annealed 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 annealed ASTM B522 class II and the bottom bar is annealed Type 4 magnetic alloy.
