6061 T4/T6/T651/6511 알루미늄 라운드 바

What Is 6061 Aluminum Round Bar?

6061 Aluminum Round Bar is made from 6061, one of the most widely used heat-treatable aluminum alloys. Its balanced mix of magnesium and silicon gives good strength after the T6/T651 aging treatment while keeping the material easy to machine and weld.

In T6 condition it delivers strong structural performance, which is why it appears across architecture, transport, and general engineering.

화학 성분

열처리 상태에 따른 기계적 특성

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

템퍼 선택 가이드

• O — soft, for heavy forming.
• T4 — naturally aged; good formability with moderate strength.
• T6 — solution heat-treated and artificially aged; the standard high-strength temper.
• T651 / T6511 — T6 with stress relief by stretching (T6511 for extrusions); best dimensional stability for machining.

주요 특징

뛰어난 가공성

T651/T6511 round bar is a workshop favorite for turned and milled parts.

High Strength and Stability

T6 temper delivers strong, dimensionally stable stock for precision work.

Versatile in Precision Engineering

Used for shafts, spindles, and fixtures where consistency matters.

내식성

Performs well indoors and in mild outdoor or marine-adjacent service.

애플리케이션

• 자동 스크류 기계 제품
• Fasteners, fittings, and shafts
• Machine parts and tooling
• Structural and bicycle components

가공 및 표면 마감 참고 사항

• 가공: 6061 machines cleanly with standard carbide tooling; T651/T6511 give the best dimensional stability.
• 용접: readily welded by TIG/MIG with 4043 or 5356 filler; strength in the heat-affected zone drops relative to T6.
• Anodizing & finishing: anodizing and powder coating available for appearance and added corrosion protection.
• 절단: supplied cut to size; standard and custom lengths supported.

품질 문서 및 검사

• 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.

6061 알루미늄 자주 묻는 질문

Is 6061 round bar heat-treatable?

Yes. It is supplied in O, T4, T6, T651, and T6511 tempers.

Which temper for machined parts?

T651 or T6511 is preferred for machining because stress relief minimizes warping after cutting.

What diameters are available?

Typical range is 6–400 mm; custom sizes can be reviewed on enquiry.

주문 관련 일반적인 자주 묻는 질문

최소 주문 수량은 어떻게 되나요?

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.

일반적인 리드 타임은 얼마인가요?

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.
