Alliage d'aluminium 5182

What Is 5182 Aluminum Alloy Aluminum?

5182 Aluminum Alloy (AlMg4.5Mn0.4) is a non-heat-treatable aluminum-magnesium (5xxx) alloy. Its strength comes from magnesium in solid solution and strain hardening, not heat treatment. It offers good corrosion resistance—especially in marine and industrial environments—and welds well, which makes it a common choice for structures exposed to water, chemicals, or cycling loads.

Guide de sélection des tempéraments

• O (recuit) : softest, best formability and corrosion resistance; for deep drawing and welding.
• H1xx / H2xx / H3xx: strain-hardened tempers with increasing strength and decreasing ductility.
• H116 / H321 : stabilized tempers for marine plate with good exfoliation-corrosion resistance.

Choose the softest temper that meets the strength need to keep forming and welding straightforward.

Caractéristiques principales

High magnesium content

At about 4.5% Mg, 5182 delivers good strength while staying formable in soft tempers.

Formabilité

Commonly used for drawn and formed parts such as automotive body panels and can stock.

Résistance à la corrosion

Good resistance in atmospheric and mildly corrosive environments.

Applications

• Automotive body panels and structures
• Beverage can and packaging stock
• Marine and transport fabrications
• Welded containers and enclosures

Remarques concernant le traitement et la finition de surface

5182 Aluminum Alloy is a non-heat-treatable 5xxx alloy, so strength comes from strain hardening (H-tempers), not heat treatment. It cuts, drills, and welds well with standard aluminum tooling.

• Découpe : CNC machining, laser cutting, and sawing are supported.
• Soudage : TIG and MIG welding with matching or compatible 5xxx filler.
• Formation : good cold formability in O and soft H-tempers.
• Finition de surface : mill finish, anodizing, polishing, powder coating, or PVC film protection.

Note: anodized color of 5xxx alloys can differ slightly from 6xxx alloys; confirm the finish on a sample if color match matters.

Documents relatifs à la qualité et contrôle qualité

Every 5086 order ships with a Mill Test Certificate (MTC) that reports the actual chemical analysis and mechanical results for the supplied material. Third-party SGS or equivalent test reports can be arranged on request for project or tender requirements.

• MTC (EN 10204 3.1 or 3.2) with every order
• Dimensional inspection against the agreed tolerance
• Surface and visual check before packing
• Material traceability by heat / lot number

5182 Aluminum Alloy Aluminum FAQ

Is 5182 heat treatable?

No. 5182 is a non-heat-treatable 5xxx alloy; strength is set by magnesium content and strain hardening.

What tempers are typical for 5182 sheet?

O, H111, H32, and H34 are common for formed and welded parts.

5182 vs 5083?

5182 is a medium-strength forming alloy (Mg ~4.5), while 5083 is a higher-strength marine plate alloy. Pick based on forming needs versus required strength.
