How it works

How the weight is calculated

A tube's weight is the metal area of its wall × length × density. For a round tube the metal area simplifies to π × wall × (OD − wall).

Tube weight formulas

Round tube
π × t × (OD − t) × L × density
Square tube
[A² − (A − 2t)²] × L × density
Rectangular tube
[W × H − (W − 2t)(H − 2t)] × L × density
6061 round, per metre
0.00848 × t × (OD − t) kg, sizes in mm

Worked example: 6061 round tube, OD 50 × 3 mm wall × 6 m: π × 0.003 × 0.047 × 6 × 2700 = 7.18 kg.

Reference data

Aluminium alloy densities used in the calculator

The calculator multiplies volume by the typical density of the selected alloy. These are the values it uses. Values are typical figures from published alloy data; the mill test certificate for your lot is the final reference.

Getting it right

Why the delivered weight differs from the theoretical weight

Dimensional tolerance

Mills supply to a tolerance band, not the exact nominal size. Plate on the plus side of its thickness tolerance can weigh 2–5% more than the calculated figure.

Alloy and temper

Density varies with the alloying elements, from about 2.64 g/cm³ for 5A06 to 2.83 g/cm³ for 7050 and 2011. Temper has no practical effect on density.

Cladding and coatings

Alclad layers, anodising, paint, PVC film and interleaving paper add small amounts of weight. Coated coil and sheet are usually quoted by net metal weight.

Packing and pallets

Freight is charged on gross weight. Wooden cases, pallets, steel strapping and coil cores typically add 3–8% on top of the metal.

Next step

What to send for a fast quotation

Weight is only the first step. To quote firm prices and availability, Metline needs:

  • Alloy and temper, for example 6061-T6 or 5083-H116
  • Exact dimensions with tolerances, or the governing standard (ASTM B209, EN 485, IS 737)
  • Quantity in pieces or kilograms, and whether cut-to-size is needed
  • Surface, protective film or finish requirements
  • Inspection documents: mill test certificate to EN 10204 3.1, third-party inspection
  • Delivery location in India or export port, and the date you need the material

Email the details to sales@metline.in or use the enquiry form. The quote button in the calculator carries your sizes into the form automatically.

FAQ

Frequently asked questions

How do I calculate aluminium pipe weight per metre?

For a round 6061 pipe, weight per metre ≈ 0.00848 × wall × (OD − wall), with sizes in millimetres. A 2-inch Schedule 40 pipe (OD 60.3 mm, wall 3.91 mm) weighs about 1.87 kg/m.

Does it matter whether the tube is seamless or welded?

Not for weight. Seamless and welded tubes of the same size and alloy weigh the same. The choice affects pressure rating, concentricity and price, so state it in your enquiry.

How accurate is this aluminium weight calculator?

It gives the theoretical weight from nominal dimensions and the typical density of the alloy. Real material is within a tolerance band, so delivered weight usually differs by a few percent. Use the result for budgeting, handling and freight planning, and rely on the weighbridge or packing list for invoicing.

What density does the calculator use for aluminium?

Each alloy has its own typical density, from 2.64 g/cm³ (5A06) to 2.84 g/cm³ (2219). If your alloy is not listed, choose "Other alloy" and enter the density from its data sheet. Pure aluminium is 2.70 g/cm³.

Can I use inches or feet?

Yes. Every dimension has its own unit selector (mm, cm, m, in or ft), so you can mix units, such as a width in inches and a length in feet. The result is always shown in kilograms and pounds.

Is the weight per piece or for the whole order?

Both. Enter the number of pieces and the calculator shows the total weight, the weight of each piece and the weight per running metre.
