5182 is a high-magnesium 5xxx aluminum alloy (AlMg4.5Mn0.4) known for its balance of strength, formability, and weldability. It is widely used for automotive body panels, packaging, and welded structures, and is supplied in sheet, plate, bar, tube, and wire across O, H32, and H34 tempers.
Available forms: sheet / plate / bar / tube / wire / coil
Common tempers: O, H111, H32, H34
Processing support: CNC machining / laser cutting / welding / anodizing
Quality documents: MTC report with every order
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.
5182 Aluminum Alloy is supplied in several forms and tempers. Standard size ranges are below; other dimensions can be discussed with our team.

Mechanical values are representative room-temperature typicals for plate, sheet, or bar and should be confirmed against the ordered thickness and the supplied MTC.
Choose the softest temper that meets the strength need to keep forming and welding straightforward.
At about 4.5% Mg, 5182 delivers good strength while staying formable in soft tempers.
Commonly used for drawn and formed parts such as automotive body panels and can stock.
Good resistance in atmospheric and mildly corrosive environments.
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.
Note: anodized color of 5xxx alloys can differ slightly from 6xxx alloys; confirm the finish on a sample if color match matters.
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.

No. 5182 is a non-heat-treatable 5xxx alloy; strength is set by magnesium content and strain hardening.
O, H111, H32, and H34 are common for formed and welded parts.
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.
Custom sizes are usually produced within 10–60 days depending on alloy, temper, and quantity. Confirm the schedule when you request a quote.
