EN 1.1151 Steel vs. 3005 Aluminum

EN 1.1151 steel belongs to the iron alloys classification, while 3005 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 1.1151 steel and the bottom bar is 3005 aluminum.
