6063 Al-Mg-Si Aluminum Alloy Rod

6063 is a low-alloy, heat-treatable aluminum alloy in the Al-Mg-Si system. It offers superior anodizing results and a high-quality surface finish compared to 6061. While its strength is lower than that of 6061, it exhibits good corrosion resistance, excellent weldability, and no tendency toward stress corrosion cracking. It is primarily used for decorative applications, lightweight components, and parts where surface appearance is important.

6063 is a low-alloy, heat-treatable aluminum alloy from the Al-Mg-Si series. It offers excellent plasticity and superior extrudability. Compared to 6061, it provides a much better finish after anodizing and achieves a higher surface quality. While its strength is lower than that of 6061, it features good corrosion resistance, excellent weldability, and no tendency toward stress corrosion cracking. It is widely used for decorative applications, lightweight components, and parts where appearance is critical. Common tempers include T5 (most frequently used) and T6; the density is 2.70 g/cm³.

Standards

Chinese National Standard (GB) for bars: GB/T 3191-2019 ("Extruded bars of aluminum and aluminum alloys"); chemical composition per GB/T 3190.

American Standard (ASTM): ASTM B221.

European Standard (EN): EN AW-6063 (AlMg0.7Si), EN 573-3.

Specifications

Shapes: Round bars (most common), square bars, hexagonal bars.

Available tempers: O, T4, T5, T6.

Tolerances: Standard extrusion tolerances / high-precision tolerances for precision-machined (turned) bright bars.

Mechanical properties

Tensile strength Rm	≥215 MPa
Yield strength Rp0.2	≥170 MPa
Post-fracture elongation A	≥10%
Brinell Hardness HB	≈75 HB

Application Scenarios

1. Architectural Decoration: Building frameworks, door and window fittings, railings, and curtain wall decorative elements.

2. Industrial Frameworks: Lightweight equipment supports, assembly line frames, and profiles for workstations.

3. Furniture and Consumer Goods: Aluminum alloy furniture, protective barriers, and components for fitness equipment.

4. Heat Dissipation Components: Simple heat sinks and cooling bases.

5. Structural/Decorative Parts: CNC-machined parts requiring anodized finishes, and enclosures for instruments or devices.

6. Small-scale Transport Components: Vehicle interior trim, handrails, and lightweight, non-load-bearing structural elements.

Not suitable for high-load-bearing applications. This material is best suited for projects requiring a high-quality aesthetic finish or anodizing; for load-bearing components, 6061 aluminum alloy is the preferred choice.

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.
