EN-MC32110 Magnesium vs. ASTM A182 Grade F122

EN-MC32110 magnesium belongs to the magnesium alloys classification, while ASTM A182 grade F122 belongs to the iron alloys. There are 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is EN-MC32110 magnesium and the bottom bar is ASTM A182 grade F122.
