Alliage d'aluminium 6082

What Is 6082 Aluminum Alloy?

6082 (EN AW-6082, AlSi1MgMn) is a heat-treatable 6000-series aluminum alloy with magnesium and silicon as the main alloying elements, plus manganese for strength and corrosion resistance. It offers a strong combination of medium-to-high strength, good corrosion resistance, and excellent extrudability, which makes it one of the most widely used structural aluminum alloys.

Compared with 6061, 6082 generally provides higher strength in thicker sections while remaining weldable and formable in the appropriate tempers. It is commonly supplied in O, T4, T6, and T651 tempers across sheet, plate, bar, tube, and extruded profiles.

Guide de sélection des tempéraments

• O (annealed): maximum formability and lowest strength; choose for deep forming.
• T4: solution heat treated and naturally aged; good formability with moderate strength.
• T6 / T651: solution heat treated and artificially aged (T651 is stress-relieved); highest standard strength for structural use.
• H112: strain-hardened for plate/extrusion with relaxed property control; general structural use.

Key Characteristics of 6082 Aluminum

Rapport force/poids

6082 delivers strong specific strength, especially in T6/T651, making it suitable for load-bearing structures.

Résistance à la corrosion

Good general corrosion resistance; in aggressive marine environments consider cladding or appropriate surface treatment.

Formabilité et soudabilité

Readily formed in O/T4 and weldable by TIG/MIG. Welded zones are softer than the base temper and should be accounted for in design.

Applications courantes

• Bridges, trusses, towers, and pylons
• Railway and transport structures, truck frames
• Marine and shipbuilding components
• Machined parts, fixtures, and wear plates
• Automotive structural components

Remarques concernant le traitement et la finition de surface

Usinage

6082 machines well in the soft (O) and solution-heat-treated tempers; T6/T651 tempers are stronger and can work-harden at the cutting edge, so sharp tooling and appropriate feeds are recommended.

Welding

6082 is generally weldable using TIG or MIG processes with matching or 4043/5356 filler, depending on the service requirement. Welded zones lose some strength compared with the base temper — design accordingly for structural use.

Forming & Heat Treatment

Forming is best done in the O or T4 condition. Final strength is developed by the specified temper; do not re-heat-treat without confirming the alloy’s response.

Finition de la surface

Common finishes include anodizing, polishing, and powder coating. Anodizing quality depends on surface preparation, so confirm finish requirements before production.

Documents relatifs à la qualité et contrôle qualité

Every 6082 order ships with a Mill Test Certificate (MTC) that reports the actual chemical composition and mechanical properties against the ordered specification. We can also arrange:

• Third-party inspection and SGS test reports on request.
• Dimension and surface inspection records for critical tolerances.
• Material certificates aligned to ASTM, EN, GB, or JIS as required.

Please confirm the required standard and any additional documentation when placing the order.

6082 Aluminum FAQ

Is 6082 the same as 6061?

No. Both are 6000-series structural alloys, but 6082 has higher manganese and typically higher strength in thicker sections, while 6061 is more common in North America and easier to source in some tempers.

Can 6082 be welded?

Yes. It welds well with TIG/MIG using appropriate filler. Note that welded zones are softer than the surrounding T6 material.

What lead time should I expect?

Stock items ship in 10–30 days; custom sizes and tempers typically 30–60 days depending on specification.
