Type 4 Magnetic Alloy vs. ASTM F15 Fe-Ni-Co
Type 4 magnetic alloy belongs to the nickel alloys classification, while ASTM F15 Fe-Ni-Co belongs to the iron alloys. They have 43% of their average alloy composition in common. There are 22 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.
For each property being compared, the top bar is Type 4 magnetic alloy and the bottom bar is ASTM F15 Fe-Ni-Co.
