EN 1.7227 Steel vs. EN-MC21110 Magnesium

EN 1.7227 steel belongs to the iron alloys classification, while EN-MC21110 magnesium belongs to the magnesium alloys. There are 24 material properties with values for both materials. Properties with values for just one material (8, 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 1.7227 steel and the bottom bar is EN-MC21110 magnesium.
