Hliníková kulatá tyč 6061 T4/T6/T651/6511

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.

Chemické složení

Mechanické vlastnosti podle způsobu temperování

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

Průvodce výběrem tvrzenosti

• 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.

Klíčové charakteristiky

Vynikající obrobitelnost

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.

Odolnost proti korozi

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

Aplikace

• Výrobky automatických šroubovacích strojů
• Fasteners, fittings, and shafts
• Machine parts and tooling
• Structural and bicycle components

Poznámky ke zpracování a povrchové úpravě

• Machining: 6061 machines cleanly with standard carbide tooling; T651/T6511 give the best dimensional stability.
• Svařování: 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.
• Řezání: supplied cut to size; standard and custom lengths supported.

Kvalitní dokumentace a kontrola

• 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.

Často kladené otázky k hliníku 6061

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.

Často kladené otázky k objednávkám obecně

Jaké je minimální množství objednávky?

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.

Jaká je typická dodací lhůta?

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.
