EN-MC32110 Magnesium vs. ASTM A514 Steel

EN-MC32110 magnesium belongs to the magnesium alloys classification, while ASTM A514 steel belongs to the iron 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 EN-MC32110 magnesium and the bottom bar is ASTM A514 steel.
