5252 Aluminum vs. ASTM A299 Steel
5252 aluminum belongs to the aluminum alloys classification, while ASTM A299 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 5252 aluminum and the bottom bar is ASTM A299 steel.
