EN 1.0070 Steel vs. 1200 Aluminum

EN 1.0070 steel belongs to the iron alloys classification, while 1200 aluminum belongs to the aluminum 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 1.0070 steel and the bottom bar is 1200 aluminum.
