Why Aluminum Tubing?
Aluminum tube offers exceptional strength-to-weight, corrosion resistance, excellent machinability, and clean cosmetics. It’s ideal for frames, automation, transport, marine, aerospace, displays, and construction.
- Lightweight structural members with high stiffness-to-weight
- Good weldability (6061/6063), strong fatigue options (2024/7075)
- Attractive surface with anodize or powder coat finishes
- Reliable global availability and consistent tolerances
Manufacturing Routes
- Extruded Structural Tube (ASTM B221/B429): best cost/performance for frames & general fabrication.
- Seamless Extruded/Seamless Pipe (ASTM B241): improved integrity and concentricity; common for schedule 40/80.
- Drawn Seamless (ASTM B210): tight OD/ID control and surface for precision or aerospace needs.

Aluminum Tube Weight Calculator
Estimate linear weight for round/square/rectangular tubing. Density prefilled at 2.70 g/cm³ (6061/6063). Adjust if needed.
How it’s calculated
- Convert mm to cm and compute cross-section area A.
- Round: A = π/4 × (OD² − ID²); ID = OD − 2×wall.
- Square: A = W² − (W − 2×wall)².
- Rect: A = W×H − (W − 2×wall)×(H − 2×wall).
- Volume V = A × length.
- Mass m = V × density. Report kg (and lb).
Round: ID = OD − 2×wall = -234.000 mm; A = π/4×(OD²−ID²). Volume = A×L; Mass = Volume×Density with ρ=2.7 g/cm³.

Frequently Asked Questions (FAQs)
Tube vs pipe — which should I choose?
Choose tube (OD × wall) for structural/precision assemblies; choose pipe (nominal × schedule) for fluid conveyance and pressure services.
Is 6061-T6 bendable?
Yes with proper tooling and radii. For tight bends, use O/T4 then age to T6 after forming.
Can you supply drawn seamless for aerospace?
Yes—drawn seamless per ASTM B210 in 2024/7075 and others upon request.
Which finishes do you offer?
Mill, brushed, clear/black anodized, powder coat. Architectural anodize recommended for 6063.
What information speeds up my quote?
Shape, OD × wall (or nominal × schedule), length, alloy/temper, quantity, finish, destination port, and any drawings/tolerance notes.
Do you offer square/rectangular tubes?
Yes—wide range of H×W and walls across 6061/6063 for frames and architectural systems.
