6060 Aluminum Alloy

What Is 6060 Aluminum?

6060 is a lower-strength member of the 6xxx (Al-Mg-Si) family, closely related to 6063 but with slightly tighter impurity control. Its main advantage is excellent extrudability and a smooth, bright finish after anodizing, which makes it the default choice for decorative and structural architectural profiles.

Like other heat-treatable alloys, its strength comes from the magnesium-silicide precipitate formed during the T5/T6 aging treatment. In the O temper it is soft and easy to bend; in T5/T6 it reaches moderate structural strength.

Available 6060 Aluminum Products

Extruded Profile & Tube

Custom cross-sections per drawing; typical section size 5–400 mm, tube outer diameter 6–300 mm, wall 0.5–20 mm, length up to 6000 mm (or coil for small sections).

Sheet & Plate

Thickness 0.5–150 mm, width 500–2600 mm, length 500–12000 mm. Sheet is typically 0.5–6 mm; plate 6–150 mm.

Bar

Round bar diameter 6–400 mm, length up to 6000 mm; cut to size on request.

Specifications & Equivalent Designations

Common standards: ASTM B221, EN 755, EN 12020, GB/T 6892.

Chemical Composition

Mechanical Properties by Temper

Values below are typical for extruded or drawn product and should be confirmed against the mill test certificate for the specific temper and section.

Temper Selection Guide

• O — soft, for bending and forming operations.
• T4 — naturally aged; moderate strength with good formability.
• T5 — cooled from extrusion and artificially aged; the most common architectural temper, good finish.
• T6 — solution heat-treated and aged; highest strength of the common 6060 tempers.

Key Characteristics

Extrudability

6060 flows well in the extrusion press, allowing thin walls and complex shapes at good press speed.

Surface Finish After Anodizing

It produces a uniform, bright anodized layer, which is why it dominates window, door, and decorative trim.

Corrosion Resistance

Good in atmospheric and mild industrial environments; suitable for indoor and most outdoor architectural use.

Weldability

Readily welded by TIG/MIG; post-weld strength in the heat-affected zone is lower than the parent T6, so design accordingly.

Moderate Strength

Enough for architectural and light structural roles, but not for highly loaded structural members (use 6061/6082 instead).

Applications

• Window, door, and curtain-wall frames
• Railings, handrails, and balustrades
• Furniture tubing and decorative trim
• Lighting tracks and fixtures
• Transport interior profiles

Processing & Surface Finish Notes

• Extrusion: primary production route; dies made to customer drawing.
• Anodizing: clear or colored anodizing is the standard finish for 6060 trim.
• Powder coating: available for color-matched architectural parts.
• Welding: TIG/MIG with 4043 or 5356 filler; minimize heat input to protect the temper.
• Machining: fair machinability; use sharp tools and appropriate speeds for the T temper.

Quality Documents & Inspection

• Material Test Certificate (MTC) supplied with every order, per EN 10204 3.1 where requested.
• Dimension and visual inspection on each shipment; ultrasonic or eddy-current testing available on request.
• Third-party testing such as SGS can be arranged for composition and mechanical verification when required (SGS provides a test report, not a company certification).
• Management system: ISO 9001 (quality), ISO 14001 (environment), ISO 45001 (occupational health and safety) — no year suffix.

6060 Aluminum FAQ

Is 6060 heat-treatable?

Yes. 6060 is a heat-treatable 6xxx alloy; its strength develops through T5/T6 aging.

6060 vs 6063 — which should I choose?

They are very similar. 6063 is slightly more common for premium architectural anodizing; 6060 offers comparable finish with marginally different impurity limits. Either works for most trim.

Can 6060 be anodized?

Yes, and it anodizes to a bright, even finish — this is its primary selling point.

What tempers are typically stocked?

O, T4, T5, and T6. T5 and T6 dominate architectural extrusion.

General Ordering FAQ

What is the minimum order quantity?

MOQ depends on form and temper. Standard sections and tempers can start from a few hundred kilograms; custom-dimension or special-temper orders are reviewed case by case.

What is the typical lead time?

For stock-available tempers, lead time is typically 10–30 days. Custom extrusion or heat-treated conditions may take up to 60 days. Confirm with our sales team at enquiry.

Can you supply cut-to-size and processing?

Yes. We offer cutting, CNC machining, welding, anodizing, and polishing. Provide your drawings or dimension list with the enquiry.

What documents come with the shipment?

Every order ships with an MTC. SGS or other third-party test reports can be arranged on request.
