EN 1.5662 Steel vs. EQ21A Magnesium
EN 1.5662 steel belongs to the iron alloys classification, while EQ21A magnesium belongs to the magnesium alloys. There are 28 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 1.5662 steel and the bottom bar is EQ21A magnesium.
