ASTM A283 Carbon Steel vs. EN-MC21210 Magnesium
ASTM A283 carbon steel belongs to the iron alloys classification, while EN-MC21210 magnesium belongs to the magnesium alloys. 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 ASTM A283 carbon steel and the bottom bar is EN-MC21210 magnesium.
