Barre plate en aluminium 6063-T5/T52/T6

What Is 6063 Aluminum Flat Bar?

6063 Aluminum Flat Bar is produced from the standard architectural Al-Mg-Si alloy, valued for its excellent surface finish, good corrosion resistance, and outstanding anodizing response. It is normally supplied in the T5 and T6 tempers and suits decorative and light-structural applications where form and finish matter.

Guide de sélection des tempéraments

• T5 — standard as-extruded temper; good strength and anodizing finish at low cost.
• T6 — solution heat-treated and aged; higher strength for structural use.
• T52 — stress-relieved for better dimensional stability after machining.
• O / T4 — available when forming or further fabrication is required.

Caractéristiques principales

Finition de la surface

Excellent anodizing and powder-coating response for decorative appearances.

Résistance à la corrosion

Good atmospheric corrosion resistance for architectural and indoor use.

Soudabilité

Readily welded by TIG/MIG; post-weld strength recovers after heat treatment.

Formabilité

Moderate strength with good formability in O and T4 tempers.

Applications

• Architectural trim and molding
• Window and door frames
• Framework and supports
• Fixtures and fittings
• Decorative finishes

Remarques concernant le traitement et la finition de surface

• Extrusion: 6063 is the most extrudable of the common 6xxx alloys; complex profiles are produced efficiently.
• Finition de surface : excellent response to anodizing and powder coating; a bright, decorative finish is readily achieved.
• Usinage : fair machinability; use sharp tooling and adequate coolant for T5/T6 tempers.
• Soudage : readily welded by TIG (GTAW) and MIG (GMAW); post-weld strength recovery is good after heat treatment.
• Formation : O and T4 tempers form well; T5/T6 are used as-extruded for structural shapes.

Documents relatifs à la qualité et contrôle qualité

• Mill Test Certificate (MTC / EN 10204 3.1) supplied with every order.
• Certified to ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (occupational health & safety).
• Third-party inspection reports (e.g. SGS) available on request for specific orders.
• Dimensional and surface inspection against ASTM / EN / GB specifications before shipment.

6063 Aluminum Flat Bar FAQ

À quoi sert l'aluminium 6063 ?

6063 is the standard “architectural aluminum” alloy. It is used for window and door frames, curtain walls, railings, furniture, heat sinks, electronics enclosures, and decorative trim where a high-quality surface finish and good anodizing response matter more than maximum strength.

Is 6063 heat-treatable?

Yes. 6063 is a heat-treatable 6xxx (Al-Mg-Si) alloy. It is most often used in the T5 and T6 tempers; T4 and O are available for forming and sheet applications.

6063 vs 6061 — which should I choose?

6063 extrudes more easily and anodizes better, making it ideal for architectural profiles. 6061 offers higher strength and better machinability, suiting structural and machined parts. Choose 6063 when finish and formability lead, 6061 when strength and machining lead.

What tempers are commonly stocked for 6063?

T5 and T6 are the standard extrusion tempers. T52 (stress-relieved) is used where dimensional stability after machining is important. Sheet is commonly supplied in T4, T5, and T6.

Can 6063 be anodized?

Yes. 6063 is one of the best alloys for anodizing and produces a bright, uniform, decorative oxide layer. It is also compatible with powder coating and wet painting.

Is 6063 suitable for marine environments?

6063 has good general corrosion resistance but is not a marine-grade alloy like 5083 or 6061. For continuous saltwater exposure, specify 5xxx or 6061 and confirm the anodizing/paint system with us.

How is 6063 flat bar supplied?

6063 flat bar is typically extruded and supplied in T5 or T6. T52 is used when stability after machining is important. Standard sizes can be cut to length; custom widths and thicknesses are developed on request.

FAQ générale sur les commandes

Quel est le délai de livraison habituel ?

Standard extrusion and stock shapes are usually delivered within 10–60 days depending on size, temper, and finishing. Custom profiles are quoted case by case.

Fournissez-vous des certificats d'essai en usine ?

Yes. An MTC (EN 10204 3.1) is supplied with every order, and third-party inspection reports can be arranged.

Can you supply custom profiles and sizes?

Yes. We develop custom 6063 extrusions and offer cut-to-length, CNC machining, anodizing, and powder coating.

Which standards do your products meet?

We work to ASTM (B221/B209/B241), EN 573/485/755, GB/T 3190/5237, and JIS H4000, among others.

How are products packed for export?

Profiles and bars are bundled and wrapped; sheets are palletized with interleaving. Seaworthy export packaging is standard, with custom crating on request.
