6066 aluminiumlegering

What Is 6066 Aluminum Alloy?

6066 aluminum is a heat-treatable 6000-series alloy containing silicon, magnesium, copper, and manganese. It delivers moderate to high strength with good corrosion resistance and is developed for extrusion, making it a practical choice for structural and industrial fabrications. Linsy supplies 6066 in T4, T6, and T651 tempers across sheet, tube, bar, and profile.

Mechanische eigenschappen per hardingsgraad

Values below are typical reference ranges; actual results vary with section thickness and temper. T6 figures reflect the supplied specification, while T4 values are typical references to be confirmed.

Temper	Treksterkte (MPa)	Opbrengststerkte (MPa)	Elongation (%, min)
T4	~200	~110	~16
T6 / T651	310 – 380	~270	10 – 12

Shear strength for T6 is around 240 MPa.

Gids voor het kiezen van de juiste temperatuur

T4 is solution heat treated and naturally aged, giving good formability right after heat treatment — useful when parts are formed before final aging. T6 / T651 are the aged tempers that deliver the higher strength needed for structural members. Choose T6/T651 for load-bearing extrusions and T4 where forming is required after heat treatment.

Belangrijkste kenmerken

Higher Strength in the 6000 Series

With its copper and manganese content, 6066 reaches higher strength than common 6061/6063 while staying extrudable.

Corrosiebestendigheid

It keeps good general corrosion resistance for structural use, though less than the lower-copper 6000-series alloys in some environments.

Vormbaarheid en lasbaarheid

6066 forms well in the T4 condition and welds with standard methods; welded zones soften locally versus the base temper.

Toepassingen

• Marine and engine-adjacent structures
• Aircraft and vehicle components
• Building frameworks and supports
• Truck bodies and rail cars
• Structural and industrial fabrications

Opmerkingen over bewerking en oppervlakteafwerking

6066 machines and forms well, especially in T4 before aging. It accepts anodizing and polishing — confirm finish and tolerance needs before production. Welding is possible with standard processes, but the heat-affected zone softens; design around it or specify post-weld treatment where strength is critical.

Kwaliteitsdocumenten en inspectie

Every 6063 square bar shipment leaves our Shenzhen plant with a Mill Test Certificate (MTC) that reports the actual chemical analysis and mechanical results for the heat. In-house checks cover dimensional tolerance, surface condition, and temper verification. Our production system is managed under ISO 9001, ISO 14001, and ISO 45001. Where a project requires it, third-party test reports (for example SGS) can be arranged on request.

Why Choose Linsy for 6063 Aluminum

Linsy is a Shenzhen-based aluminum supplier with more than 20 years of production experience across the 1000 to 8000 series. For 6063 we support both standard extruded profiles and made-to-order sections, with in-house cutting, CNC machining, and anodizing or polishing finishes. Common tempers and sizes are held for faster turnaround, while custom dimensions are produced to order. Each order ships with an MTC so procurement and quality teams can verify the material before it enters production.

6066 Aluminum FAQ

What tempers are available for 6066?

We commonly supply T4, T6, and T651 across sheet, tube, bar, and profile.

How does 6066 differ from 6061?

6066 contains more silicon, copper, and manganese, giving it higher strength than 6061 while remaining extrudable; it is selected where extra strength is needed.

Is 6066 good for welding?

Yes, it welds with standard methods, though as with other heat-treatable alloys the welded zone loses some strength compared with the base temper.

Veelgestelde vragen over bestellingen in het algemeen

Wat is de gebruikelijke levertijd?

Standard tempers and sizes are usually available within 10–60 days. Custom extrusion or machining lead times depend on section complexity and order volume — we confirm a date when the specification is fixed.

Do you provide an MTC with each order?

Yes. A Mill Test Certificate is issued for every shipment, reporting chemical composition and mechanical properties for the supplied heat.

Can sizes and tempers be customized?

Yes. We cut to length and produce custom cross-sections and tempers on request. Share your drawing or required dimensions and we will confirm feasibility.

Which surface finishes are available?

Common options include mill finish, anodizing, and polishing. Specific finishes should be confirmed against your application and tolerance needs.

Which certifications does Linsy hold?

Our management system is certified to ISO 9001, ISO 14001, and ISO 45001. Third-party test reports such as SGS can be provided on request for specific orders.
