6063-T5/T52/T6 알루미늄 사각 튜브

What Is 6063 Aluminum Square Tube?

6063 aluminum square tube is a medium-strength, heat-treatable extruded profile known as architectural aluminum. It offers a clean surface finish, strong anodizing response, and good weldability, making it suitable for both structural frameworks and decorative assemblies. Linsy supplies 6063 square tube in T5 and T6 tempers, with custom outer dimensions and wall thicknesses.

템퍼 선택 가이드

T5 is cooled from extrusion and artificially aged, giving good strength with efficient production for most frameworks and displays. T6 is solution heat treated then aged, providing the highest 6063 strength for structural or load-bearing tube. Choose T6 where the design needs more margin, and T5 where finish and cost lead.

주요 특징

Surface Finish & Anodizing Response

6063 square tube anodizes evenly, which is why it is widely used for visible architectural frameworks.

내식성

The alloy performs well in normal atmospheric and mildly industrial environments without extra coating.

성형성 및 용접성

6063 welds with standard methods and is easy to cut and assemble; note that welded zones soften locally versus the base temper.

애플리케이션

• Architectural frameworks
• Window and door frames
• Displays and exhibits
• Furniture and fixtures
• Railings and supports

가공 및 표면 마감 참고 사항

6063 square tube cuts and machines cleanly. It is well suited to anodizing and polishing — confirm coating and tolerance needs before production. Welding is straightforward, but expect some strength loss in the heat-affected zone; design around it or specify post-weld treatment when load matters.

품질 문서 및 검사

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.

6063 Aluminum Square Tube FAQ

What tempers are available for 6063 square tube?

We commonly supply T5 and T6; other tempers such as O, T4, and T52 can be arranged on request.

What outer sizes and wall thicknesses can you produce?

Typical square tube runs from about 15 mm to 200 mm outer, with wall thickness 1–10 mm. Custom sizes are available on confirmation.

Is 6063 square tube weldable?

Yes. 6063 welds well with standard processes, though the welded area softens relative to the base temper.

주문 관련 일반적인 자주 묻는 질문

일반적인 리드 타임은 얼마인가요?

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.
