6061 T4/T6/T651/6511 Aluminium-Flachstahl

What Is 6061 Aluminum Flat Bar?

6061 Aluminum Flat 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.

Gängige Normen: ASTM B221, ASTM B211, EN 755, GB/T 6892.

Chemische Zusammensetzung

Mechanische Eigenschaften je nach Temperierung

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

Leitfaden zur Auswahl der Härtung

• 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.

Wesentliche Merkmale

Hohes Festigkeits-Gewichts-Verhältnis

T6 flat bar carries real structural load at a fraction of steel’s weight.

Gute Bearbeitbarkeit

Cuts and drills cleanly, ideal for CNC-produced brackets and parts.

Schweißeignung

Joins reliably by TIG/MIG; design around post-weld temper loss.

Korrosionsbeständigkeit

Handles atmospheric and mild marine exposure with optional anodizing.

Anwendungen

• Machined parts and fasteners
• Structural and architectural supports
• Brackets, fixtures, and machine bases
• Transportation and marine fittings

Hinweise zur Bearbeitung und Oberflächenveredelung

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

Qualitätsdokumente und Qualitätsprüfung

• Werkstoffprüfzeugnis (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.

Häufig gestellte Fragen zu 6061-Aluminium

Is 6061 flat bar heat-treatable?

Yes. It is supplied in O, T4, T6, T651, and T6511; T6/T651 are the structural tempers.

6061-T6 vs T651 — what is the difference?

T651 is stress-relieved by stretching after aging, giving better dimensional stability and less warping after machining.

Can flat bar be cut to size?

Yes. Standard and custom lengths are supplied cut to your dimension list.

Allgemeine Fragen zur Bestellung

Wie lautet die Mindestbestellmenge?

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.

Wie ist die typische Lieferzeit?

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.
