ASTM A372 Grade E Steel vs. 5154A Aluminum
ASTM A372 grade E steel belongs to the iron alloys classification, while 5154A 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 ASTM A372 grade E steel and the bottom bar is 5154A aluminum.
