1050A Aluminum vs. EN 1.5113 Steel

1050A aluminum belongs to the aluminum alloys classification, while EN 1.5113 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 1050A aluminum and the bottom bar is EN 1.5113 steel.
