High-formability Al-Mg sheet
5182 Aluminium Sheet
5182 is a 4.5 % magnesium sheet alloy that combines high strength with excellent formability in the annealed state. It is the standard material for beverage can ends, a leading choice for automotive inner body panels, and a common shell plate for road tankers. Metline supplies 5182 sheet and coil in O, H111, H19 and H48 to ASTM B209 and EN 485, worldwide.

What is 5182 aluminium?
5182 is a high-magnesium (4.0 – 5.0 %) alloy with a lower manganese content than 5083. That chemistry gives very high work hardening, so annealed sheet stretches and draws deeply while finished parts end up strong.
Three industries depend on it. In packaging, 5182-H19 and H48 are rolled very thin for beverage and food can ends, where high strength allows thinner gauge and the alloy survives the severe forming of the rivet and score for the opening tab. In automotive, 5182-O is used for inner door, bonnet and boot-lid panels, where its deep-drawing ability matters more than surface appearance. In road transport, 5182-O and H111 plate is rolled into tanker shells and pressed into heads under EN 14286.
One limitation shapes its use on cars: 5182-O forms Lüders bands (stretcher-strain marks) after small amounts of plastic strain. These visible lines are unacceptable on outer panels, so 5182 is used for inner panels while outer skins use 6xxx alloys. Special stretcher-strain-free processing reduces the effect where needed.

5182 tempers
H111
Annealed and lightly levelled. Tanker shells and flat plate for welded structures.
H19
Extra-hard cold-rolled can-end stock; high strength in very thin gauges.
H48
Strain hardened then lacquered or coated, the lacquer cure acting as a partial anneal. Standard for coated can ends and tabs.
H2x / H3x
Intermediate tempers can be produced on request for specific parts; strength is agreed per specification.
Not a marine temper
5182 is not normally produced in the corrosion-tested H116 or H321 tempers. For hull plating, use 5083 or 5086.

Forming, joining and finishing
Forming
Excellent stretch and deep drawing in O. Expect Lüders bands on unpainted visible surfaces; use stretcher-strain-free material or keep parts hidden.
Welding
MIG and TIG with ER5183 or ER5356; resistance spot welding and adhesive bonding are common in vehicles.
Temperature
With more than 3 % magnesium, avoid sustained service above about 65 °C to prevent sensitisation.
Paint bake
Unlike 6xxx outer-panel alloys, 5182 does not gain strength in the paint-bake cycle; it may soften slightly.
Corrosion
Good resistance in atmospheric and many chemical environments.
Coating
Takes coil coatings and lacquers well, which is essential for can stock.
Where 5182 is used
- Packaging: beverage and food can ends, ring-pull tabs and easy-open ends
- Automotive: inner door, bonnet and boot-lid panels, reinforcements and structural brackets
- Road tankers: shells, heads and baffles for ADR fuel tankers
- Industrial: shutters, pressed housings and containers

5182 aluminium (aluminum) sheet: frequently asked questions
Why is 5182 used for can ends?
Its high magnesium content gives very high strength after cold rolling (about 420 MPa in H19), so ends can be made thinner, and it survives the severe forming of the rivet and score.
Can 5182 be used for car outer panels?
Usually not. In O temper it forms stretcher-strain marks (Lüders lines) that show through paint. It is used for inner panels; outer skins use 6xxx alloys such as 6016 or 6111.
Is 5182 suitable for marine use?
It resists seawater well, but it is not produced in the corrosion-tested H116 or H321 tempers required for hull plating. Use 5083 or 5086 for marine structures.
Can 5182 be welded?
Yes, by MIG, TIG and resistance spot welding, normally with ER5183 or ER5356 filler.
What is the difference between 5182-H19 and H48?
H19 is extra-hard as-rolled; H48 is strain hardened then lacquered, the curing cycle slightly stabilising the metal. H48 is supplied ready-coated for can ends.
