Алюминиевый лист 6061 T4/T6/T651/6511

What Is 6061 Aluminum Sheet?

6061 is one of the most widely used heat-treatable aluminum alloys. In sheet form it offers an excellent balance of strength, weldability, and corrosion resistance, which makes it suitable for both fabricated structures and machined parts. The T6 temper delivers the highest strength, while O and T4 are preferred when forming or welding come first.

Available 6061 Aluminum Sheet Products

Лист и плита

6061 sheet and plate are supplied in thicknesses from 0.5 mm up to 150 mm, with widths of 1000 – 3000 mm and lengths of 1000 – 6000 mm. Thin gauge is typically supplied in O or T6; thicker plate is commonly T651 (stress-relieved by stretching).

Спецификации и эквивалентные обозначения

• AA / UNS: 6061 (A96061)
• EN AW: EN AW-6061 (AlMg1SiCu)
• Распространенные стандарты: ASTM B209, EN 485, GB/T 3880, JIS H4000

Химический состав

Механические свойства в зависимости от состояния обработки

The values below are typical room-temperature properties for 6061 and are representative of extruded, drawn, or rolled product. Exact numbers vary with section size and product form; final inspection is reported on the MTC.

Руководство по выбору температуры

• O: fully softened; best for deep drawing and welding where strength is secondary.
• T4: solution heat-treated and naturally aged; good formability with moderate strength.
• T6: solution heat-treated and artificially aged; maximum strength for structural use.
• T651: T6 with stress relief by stretching; improved dimensional stability for machined plate.

Основные характеристики

Strength and Weight

6061-T6 reaches about 310 MPa tensile strength at roughly one-third the density of steel, giving a strong strength-to-weight ratio for transport and structural parts.

Свариваемость

6061 welds well with TIG and MIG processes. Welded zones lose some strength locally, so design allowances are common for load-bearing joints.

Устойчивость к коррозии

Good general corrosion resistance; T6 performs well in atmospheric and mild industrial environments. Anodizing further improves surface protection.

Приложения

• Bicycle frames and sporting goods
• Architectural panels and railings
• Marine and ship-building fittings
• Heat exchangers and welded assemblies
• Machine parts and consumer goods

Примечания по обработке и отделке поверхности

• Механическая обработка: good in T6; use sharp tooling and appropriate coolant.
• Формовка: O and T4 form more easily than T6; observe minimum bend radii.
• Сварка: 4043 or 5356 filler is typical; post-weld heat treatment is rarely used.
• Finishing: anodizing and powder coating are standard; avoid contamination before anodizing.

Документация по качеству и контроль качества

• Сертификат испытаний на заводе (MTC): every shipment includes an MTC reporting chemical analysis and mechanical results against the ordered specification.
• Inspection: dimensional checks, visual surface inspection, and mechanical sampling are carried out before dispatch.
• Standards: material can be supplied to ASTM, EN, GB/T, or JIS requirements on request.
• Third-party testing: SGS or other nominated laboratory reports can be arranged when required by the project.

6061 Aluminum Sheet FAQ

What is the difference between 6061 T6 and T651 sheet?

T6 is solution heat-treated and artificially aged. T651 is the same热处理 condition with an added stress-relief stretch, which reduces residual stress and improves dimensional stability after machining.

Can 6061 sheet be welded?

Yes. It is one of the more weldable heat-treatable alloys; 4043 or 5356 filler is commonly used, though the weld zone is softer than the base T6 material.

Is 6061 sheet suitable for marine use?

It performs well in many marine applications, though 5xxx alloys are often preferred for continuously wetted structures. Proper finishing helps longevity.

Общие вопросы и ответы по оформлению заказов

Каковы обычные сроки выполнения заказа?

Standard stock sizes are usually dispatched within 10 – 60 days depending on temper, form, and finishing. Custom-cut or specially heat-treated material is confirmed at quotation.

Do you provide mill certificates?

Yes. An MTC is supplied with every order, and third-party test reports (for example SGS) can be arranged on request.

Which standards can you supply to?

We can work to ASTM, EN, GB/T, JIS, and customer-specific drawings. Please share the required standard when requesting a quote.

Can material be cut or machined before shipping?

Yes. Cutting-to-length, CNC machining, and basic fabrication are available; discuss your requirements when ordering.
