What Is The Density Of Aluminum? 

The density of aluminum always plays a critical role when it comes to the selection of aluminum metal. You all know that aluminum is a very cheap and abundantly available metal and a great replacement for the expensive copper in the electrical field. Aluminum is a lightweight silvery-white metal of main Group 13 of the periodic table. It is the most abundant metallic element in Earth’s crust and the most widely used non ferrous metal. The atomic number of aluminum is 13 and its atomic weight is 26.9815. So, without any delay let’s get started and know about the density of aluminum

What Is The Density Of Aluminum? 

The density of aluminum is about 2,710 kg/m3. But the density of aluminum foil is greater than 2700 kg/m3.  The density of the alloys of aluminum does not vary widely from this figure ranging between 2,640 kg/m3 and 2,810 kg/m3. aluminum density is unique in various ways and makes this material the popular choice for many applications. Some of the benefits of aluminum have to offer to include lightweight, resistance to corrosion, electrical and thermal conductivity, recyclable, etc. 

Now you know the density of aluminum kg m3, let’s know the aluminum density in different units. 

So, the density of aluminum lb/in3 is 0.1 lb/in3, while the density of aluminum in lb/ft3 is 169  lb/ft3. as well, the density of aluminum g cm3 is 2.70 g/cm3 and the density of aluminum 6061 is 2.7 g/cm3

Now you know the density of aluminum in kg and also in other units too. Let me tell you about the definition as well as the calculation of the aluminum density in detail. 

Definition Of Density Of Aluminum 

The density of aluminum is defined as the mass of aluminum metal per unit given the volume of the aluminum metal. It gives you a measure of the amount of aluminum contained in the given volume of substances. The aluminum density is a function of temperature and also pressure. Its SI unit is kilogram per cubic metre but for the general purpose, the more conveniently used unit is grams per cubic centimeter.  

The aluminum density is dependent upon the temperature, and it has been found that with an increase in temperature, the density of aluminum decreases. This means the aluminum density is inversely proportional to the temperature. Therefore, the density of aluminum at different temperatures holds different values. The definition of aluminum density in symbolic form is as,

The density of aluminum = mass of aluminum/ volume of aluminum kg/m3

                                       ⍴  = m/ v   kg/m3  

Where, m is the mass of aluminum 

            V is the volume of the aluminum, and 

            ⍴ is the density of aluminum kg/m

How To Calculate Density Of Aluminum? 

To calculate the density of the aluminum, go with the procedure given below. 

  • First of all, determine the mass of the aluminum metal. 
  • Determine the volume of aluminum. You can use the formula of the volume to calculate it according to the shape of aluminum metal. 
  • Now, divide the mass by the volume, and you will get the aluminum density. 

Let’s understand by taking an example. 

A rectangular piece of aluminum with a height of 5m, a width of 2m, and a length of 7m. The mass of the aluminum piece is 140 grams, then find its density. 

So, the density of aluminum = mass of aluminum/ volume of aluminum kg/m3

First of all, 

Find out the volume, so the volume of rectangular piece of aluminum is = length x height x width 

                                           V =  7 x 5 x 2 = 70 m3  

Now, divided the mass by volume, 

So, density of aluminum is =  140 / 70 = 2 g/m3

What Is The Exact Density Of Aluminum?

The density of aluminium is about 2,710kg/m3. The density of the alloys of aluminium does not vary widely from this figure ranging between 2,640kg/m3 and 2,810kg/m3.

What Is The Density Of Aluminum In Cubic Inches?

Density of Aluminum [Al]. In Imperial or US customary measurement system, the density is equal to 168.4931 pound per cubic foot [lb/ft³], or 1.5601 ounce per cubic inch [oz/inch³] .

Why Is Aluminium Not Dense?

Aluminium has three electrons in its outer shell, and can form three bonds. Aluminium has a face-centered-cubic (fcc) structure which means the density is related to the cube of inter-atomic separation. For element of similar atomic mass this arrangement results in lower densities.

What Is The Weight Of Aluminum?

Aluminum has an atomic weight of 26.9815 in Daltons or grams per mole (g/mol). This means if you have a certain number of moles of aluminum, you can multiply it by the atomic weight to figure out how many grams per mole of aluminum you have. This accounts for the weight of aluminum in its pure form.       

Is Aluminium High Density?

Low density is one of the main advantages of aluminum over other structural metals. Aluminum has a density that measures at about one-third the density of steel or copper.    


While going through this article you became well aware of the aluminum density and its definition. The aluminum is easily identified from its silvery white color with a bluish tint. In its pure form, it is a soft metal, but when alloyed, it hardens and becomes strong. Also, it has various chemical properties. As it occurs as a compound mainly in bauxite which is a mixture of aluminum and oxygen and other elements. Bauxite is the main source of aluminum. So, this was all about the density of aluminum.
