The density of iron is 7.87 g/cm3 near room temperature while the density of aluminum is 2.70 g/cm3 near room temperature. Therefore, this difference in densities describes that iron is heavier than aluminum. However, both are metals and very important in different industrial applications.
iron and aluminum have a closely related appearance, and they are useful as metal or as chemical compounds. However, there are several differences between iron and aluminum in their chemical and physical properties. The key difference between iron and aluminum is that iron is heavier than aluminum.
IRON
Iron is a chemical element having the atomic number 26 and the chemical symbol Fe. It is a metal in the first transition series. When considering the abundance, it is the most abundant metal on earth by means of mass. Thus, it forms most of the parts of the outer and inner core of the earth.
Atomic number = 26
Standard atomic weight = 55.84
Group = 8
Period = 4
Block = d block
Electron configuration = [Ar]3d64s2
Melting point = 1538 °C
Boiling point = 2862 °C
Oxidation states = −2 to +7 (most common are +2 and +3)
ALUMINUM
Aluminum is a chemical element having the atomic number 13, and the chemical symbol is Al. It is a silvery-white, shiny metal that resembles iron. Also, when considering its abundance, it is the 3rd most abundant metal on earth’s crust. Moreover, this metal has a wide range of applications due to its lightweight and the corrosion resistance through passivation.
Atomic number = 13
Standard atomic weight = 27
Group = 13
Period = 3
Block = p block
Electron configuration = [Ne]3s23p1
Melting point = 660.32 °C
Boiling point = 2470 °C
Oxidation states = +3 is the stable oxidation state

IRON :
- It is less reactive than aluminium.
- It reacts with moist air which corrodes the metal to form rust.
- It is magnetic.
- The atomic number is 26.
- Is not as good as a conductor of electricity than aluminium
ALUMINIUM :
- It is more reactive than iron in the reactivity series
- When it reacts with air, it forms a coating which prevents it from corroding (it forms aluminium oxide, Al₂O₃)
- It is non magnetic
- It's atomic number is 13
- Better conductor of electricity than iron
