513.0 Aluminum vs. ASTM A285 Carbon Steel

513.0 aluminum belongs to the aluminum alloys classification, while ASTM A285 carbon 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 513.0 aluminum and the bottom bar is ASTM A285 carbon steel.
