What is the Density of Aluminum？

Aluminum is a soft, lightweight metal that ranges in appearance from silver to dark gray, depending on its surface roughness. The density of aluminum alloy depends on its alloying elements

What is density?

The mass per unit volume of a substance is called density, which is represented by the symbol ρ, and its calculation formula is ρ=m/v (m is mass, v is volume). The concept of density can be used to solve a series of practical problems, such as calculating the mass of blanks, identifying metal materials, etc.

Density of Aluminum

The density is mainly related to the alloying elements and content in the aluminum alloy. The smaller the volume of magnesium and silicon, the lower the density; the higher the volume of iron, manganese, copper, zinc, and other elements, the greater the density. Basically, it will be between 2.6-2.9 g/cm³.

How to Calculate Weight by the Aluminum Density?

The mass of aluminum alloy is: m=l*w*δ*p (the letter l represents the length, the letter w represents the width, the thickness of the metal plate is usually represented by the Greek letter symbol δ, and the letter p represents the density.)

Step 1: Find its density according to the grade of aluminum alloy

The density of aluminum alloy varies according to the alloying elements added, generally between 2.6 g/cm³ and 2.9 g/cm³. The density of aluminum varies with its purity; the higher the impurity content, the greater its density. We know the density of aluminum 7075 is 2810 kg/m³(2.810 g/cm³) by looking up the table above.

Step 2: Calculate the volume of aluminum alloy

The volume of aluminum alloy material is equal to length x width x thickness. That is, V= l*w*δ

For example: An aluminum alloy plate is 6mm thick, 1200mm wide, and 2440mm long.

Its volume is (the density of the aluminum alloy plate is known to be 0.00275g/mm 2440mm*1200mm*6mm=17568000mm

Step 3: Calculate the mass of aluminum alloy

The mass density of aluminum alloy material x volume, that is, m=p*V
Still, the previous example: An aluminum 7075 plate is 6mm thick, 1200mm wide, and 2440mm long, the density of the aluminum 7075 plate is known to be 0.0.00281 g/mm³:
m=2440mm*1200mm*6mm*0.00281 g/mm³=49366.08 g
