Aluminium pipe weight calculator and weight chart.
Aluminium pipe weight (kg/m) = (OD − t) × t × 0.008482, with OD and wall t in mm. A 1" × 1.6 mm (25.4 × 1.6) aluminium tube weighs 0.32 kg/m. Alloys such as 6061 and 6063 are close to 2.70 g/cm³.
Material detailsDensity: 7.85 g/cm³
Estimate costOptional rate per kg
Theoretical weight from nominal size and density. Actual weight varies within mill tolerances.

Frequently asked questions
How do you calculate aluminium pipe weight?
Weight (kg/m) = π × (OD − t) × t × 2.70 / 1000, with OD and wall t in mm.
How much lighter is aluminium than steel?
Aluminium at 2.70 g/cm³ weighs about 34% of mild steel (7.85) for the same size.
Which aluminium alloys are used for pipes?
6061 and 6063 are the most common for tubes and pipes; 5083 is used in marine work.
What does a 50 mm OD × 3 mm aluminium tube weigh?
Using 2.70 g/cm³, the theoretical mass is about 1.196 kg/m or 7.176 kg for 6 m. This is a geometric estimate; confirm alloy density, actual dimensions and tolerance for the purchase.
