Annealed Type 2 Magnetic Alloy vs. ASTM A387 Grade 11 Class 1
Both annealed Type 2 magnetic alloy and ASTM A387 grade 11 class 1 are iron alloys. Both are furnished in the annealed condition. They have 52% of their average alloy composition in common. There are 25 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 Type 2 magnetic alloy and the bottom bar is ASTM A387 grade 11 class 1.
