The **aluminium circle weight calculator** mainly involves its density, thickness and diameter. Here we Haomei Aluminum will offer weight calculation formula and weight chart to help you calculate the accurate weight of an aluminum circle.

The aluminium circle weight calculation formula is:

Weight (g) = π × Radius² × Thickness x Density of aluminum (g/cm³)

where π is the circumference (about 3.14159), radius is the radius of the aluminium circle, and thickness is the thickness of the circular piece.

The following are the basic steps for calculating the weight of aluminium circle:

Determine the density of aluminum: Aluminum has a density of approximately 2.7 g/cm³ (this value will vary slightly depending on the purity of the aluminum and the composition of the alloy).

Measure the thickness and diameter of the aluminium circle:

Diameter (D): Measure the diameter of the aluminium circle using a suitable tool (e.g. caliper).

Thickness (T): Again, use a suitable tool to measure the thickness of the aluminium circle. Note that thickness here is usually measured in millimeters (mm) or centimeters (cm).

Calculate the area of the aluminium circle: The area of the aluminum circle is π × (D/2)^2, where D is the diameter of the aluminum circle

Calculating the Volume of an aluminum circle: The volume of an aluminium circle is its area multiplied by its thickness, i.e., π × (D/2)^2 × T.

Calculate the aluminium weight: The weight of an aluminum circle is its volume multiplied by the density of the aluminum, i.e., π × (D/2)^2 × T × 2.7 (if the density is in g/cm³ and the thickness is in cm).

For example, if the diameter of an aluminum circle is 10 cm, the thickness is 0.5 cm, and we use 2.7 g/cm³ as the density of aluminum, then the weight of the aluminum circle is calculated as follows:

Area = π × (10/2)^2 = 78.54 cm²

Volume = 78.54 × 0.5 = 39.27 cm³

Weight = 39.27 × 2.7 = 106.029 g (or about 106 g)

Note: In practice, the calculated weight may differ slightly from the actual weight due to measurement errors and the specific composition of the aluminum alloy.
