6063 Alüminyum Alaşım

What Is 6063 Aluminum Alloy?

6063 is a heat-treatable aluminum-magnesium-silicon (Al-Mg-Si) alloy with low alloying content, which gives it outstanding extrudability and a clean, bright surface after anodizing. Its strength is moderate (lower than 6061), but its combination of formability, corrosion resistance, and finish quality makes it the most widely used architectural extrusion alloy worldwide.

Temper Seçim Kılavuzu

• T5 — the standard as-extruded temper for most architectural profiles; good strength and finish at low cost.
• T6 — solution heat-treated and artificially aged; higher strength than T5 for structural or load-bearing sections.
• T52 — stress-relieved by stretching; best dimensional stability after machining.
• T4 — naturally aged; used for sheet and parts that will be formed before final aging.
• O — annealed; selected when maximum formability is required.

Temel Özellikler

Ekstrüde Edilebilirlik

Highest among common 6xxx alloys — complex, thin-wall profiles are produced efficiently.

Yüzey İşlemi

Takes anodizing and powder coating exceptionally well; bright, uniform decorative finishes.

Korozyon Direnci

Good general atmospheric corrosion resistance; suitable for indoor and most outdoor architectural use.

Kaynaklanabilirlik

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

Güç

Moderate — lower than 6061, adequate for most architectural and light structural roles.

Uygulamalar

• Pencere, kapı ve perde duvar çerçeveleri
• Handrails, balustrades, and railings
• Furniture, display, and shop-fitting profiles
• Heat sinks and LED lighting housings
• Electronics enclosures and frames
• Solar panel framing
• Decorative trim and architectural ornaments

İşleme ve Yüzey Kaplama Notları

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

Kalite Belgeleri ve Denetim

• 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 FAQ

6063 alüminyum ne için kullanılır?

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.
