6063 Al-Mg-Si aluminum alloy tube

6063 is a heat-treatable, wrought aluminum alloy belonging to the Al-Mg-Si (aluminum-magnesium-silicon) series and is the quintessential alloy for extruded aluminum tubes and profiles. Its key characteristics include excellent extrudability, a smooth and fine surface finish, superior anodizing performance, atmospheric corrosion resistance, and a lightweight nature; it is also weldable and easy to bend and machine.

6063 Al-Mg-Si alloy, commonly known as "architectural aluminum alloy," is the classic grade for extruded aluminum tubes and profiles. Key characteristics include excellent extrudability, a smooth and fine surface finish, superior anodizing performance, atmospheric corrosion resistance, light weight, and ease of welding, bending, and machining. It offers moderate strength—lower than that of 6061—making it suitable for lightweight structural components not subject to heavy loads. Density: 2.70 g/cm³.

Common supply tempers:

T5: Air-cooled after extrusion followed by artificial aging; offers the best cost-performance ratio and is the preferred choice for architecture, decoration, and general-purpose frames. Tensile strength ≥160 MPa, yield strength ≥110 MPa, HB ≈ 60.

T6: Solution heat treatment followed by water quenching and artificial aging; offers higher strength. Tensile strength ≥215 MPa, yield strength ≥170 MPa, HB ≈ 75.

6063 aluminum tubing primarily consists of extruded seamless round tubes, though square, rectangular, and special-shaped tubes can also be produced; a small quantity of precision cold-drawn tubes is available.

Surface Treatment

Anodizing (natural/black, 5–20 μm): Preferred option; provides a dense, easy-to-clean, and corrosion-resistant finish; the top choice for medical devices and outdoor applications.

Powder coating, antimicrobial coating, polishing, and brushed finish.

Note: Bare aluminum surfaces oxidize easily; direct use in outdoor or clean-room environments is not recommended.

Application Scenarios

1. Construction (Largest usage volume)

Door and window frames, balcony railings, stair handrails, curtain wall frameworks, sunshade brackets, canopy tubing, decorative railings

2. Industrial Equipment & Frameworks

Equipment frames, instrument stands, conveyor rails, workbench supports, photovoltaic (solar) mounting structures, lightweight frames for automation equipment, light poles, display stands

3. Transportation & Leisure

Bicycle frames, hand trucks, strollers, luggage handles, marine interior structural components

4. Medical (External use only; not for human implantation)

Medical emergency carts, instrument trolleys, hospital bed side rails, wheelchair frames, mobile monitor stands, hospital corridor handrails; for external support frameworks only—must not come into contact with blood or internal tissues

5. Furniture & Others

Furniture frames, bathroom fixture supports, lightweight tubing for fitness equipment, irrigation piping

Payment Methods

Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
