Aluminum Weight Calculator — Sheet, Rod, Tube & Bar
Instantly find the weight of any aluminum piece — flat sheet, round rod, square bar, or hollow tube — by entering the dimensions and your alloy density. Supports metric and imperial inputs and outputs weight in kilograms, pounds, and grams.

How does this calculator work?
Aluminum weight = volume × density. For a flat sheet: L × W × T × 2710 kg/m³; for a round rod: π × r² × L × 2710 kg/m³; for a hollow tube subtract the inner cylinder. Default density 2710 kg/m³ covers most 6061/6063 alloys; adjust for your specific alloy using its datasheet value.
Formula
How this is calculated
All material weight calculations come down to the same principle: weight equals volume multiplied by density. This calculator computes the volume of the selected aluminum shape from the entered dimensions and then multiplies by the alloy density you specify.
For a flat sheet or plate the volume is simply length × width × thickness. For a round rod it is the cross-sectional area (π × radius²) times the length. A square bar uses side² times length. A hollow tube (round tube) subtracts the inner circular area from the outer: π × (r_outer² − r_inner²) × length, where the inner radius equals the outer radius minus wall thickness.
The default density of 2710 kg/m³ covers most common structural aluminum alloys (6061, 6063, 5052). Denser alloys such as 7075-T6 (≈ 2810 kg/m³) or pure aluminum (2699 kg/m³) can be entered in the density field. Cast alloys and composites will differ further — always use the datasheet value for critical applications.
Frequently asked questions
Pure aluminum has a density of about 2700 kg/m³. Common wrought alloys (6061, 6063, 5052) are 2700–2720 kg/m³; high-strength 7075-T6 is about 2810 kg/m³. Cast alloys vary from 2640 to 2880 kg/m³.
For an angle profile, decompose it into two rectangular bars (deducting the corner overlap), compute the volume of each, then add them. Alternatively, look up the manufacturer's weight-per-metre spec from the extrusion datasheet, which accounts for exact corner radii.
Yes — just change the density. Steel ≈ 7850 kg/m³, copper ≈ 8960 kg/m³, titanium ≈ 4507 kg/m³, brass ≈ 8500 kg/m³. The formula (volume × density) is universal.
