Aluminium AlMg3 (EN AW-5754) datasheet
AlMg3 is the aluminium alloy for sheet that has to last outdoors and near water: not heat treatable, easy to weld and resistant to seawater. Below are the values from EN 573-3 and EN 485-2 for sheet up to 6 mm, with their sources.

Mechanical properties
Limits to EN 485-2 for sheet, by temper and thickness. Tensile strength, proof stress and elongation are guaranteed values. The inspection certificate states which temper was delivered.
| Condition | Thickness (mm) | Rp0.2 (MPa) | Rm (MPa) | A50 (%) | Hardness (HBW) | Min. bend radius |
|---|---|---|---|---|---|---|
| O/H111 (soft) | > 0.5 ≤ 1.5 | ≥ 80 | 190–240 | ≥ 14 | ≈ 52 | 0.5 t |
| O/H111 (soft) | > 1.5 ≤ 3 | ≥ 80 | 190–240 | ≥ 16 | ≈ 52 | 1 t |
| O/H111 (soft) | > 3 ≤ 6 | ≥ 80 | 190–240 | ≥ 18 | ≈ 52 | 1 t |
| H22/H32 (quarter hard) | > 0.5 ≤ 1.5 | ≥ 130 | 220–270 | ≥ 8 | ≈ 63 | 1 t |
| H22/H32 (quarter hard) | > 1.5 ≤ 3 | ≥ 130 | 220–270 | ≥ 10 | ≈ 63 | 1.5 t |
| H22/H32 (quarter hard) | > 3 ≤ 6 | ≥ 130 | 220–270 | ≥ 11 | ≈ 63 | 1.5 t |
| H24/H34 (half hard) | > 0.5 ≤ 1.5 | ≥ 160 | 240–280 | ≥ 6 | ≈ 70 | 1.5 t |
| H24/H34 (half hard) | > 1.5 ≤ 3 | ≥ 160 | 240–280 | ≥ 7 | ≈ 70 | 2 t |
| H24/H34 (half hard) | > 3 ≤ 6 | ≥ 160 | 240–280 | ≥ 8 | ≈ 70 | 2.5 t |
Hardness and bend radius are for information only. The bend radius is the smallest inside radius for a 90° bend, as a multiple of the sheet thickness t. Rm and Rp0.2 are the same in every thickness band up to 6 mm; only elongation and bend radius change.

Processing
Heat treatment
Not heat treatable: its strength comes from cold work during rolling alone. Soft annealing at 360 to 380 °C for 1 to 2 hours, cooled in the furnace.[1][4]
Welding
Very good weldability with MIG and TIG. thyssenkrupp recommends AlMg3 (Al 5754) or AlMg5Mn (Al 5556A/B) as filler. Klöckner rates resistance welding only as fair.[1][2]
Forming and bending
Good cold formability: Klöckner rates bending at 2 and deep drawing in temper O at 2 as well, on a scale from 1 (very good) to 6. The smallest bend radii are in the table. For parts that will be bent, order H111 or H22/H32: H12, also quarter hard, reaches only 5 to 7 % elongation.[1][2]
Corrosion
Very good resistance to weather and seawater. The soft temper resists best: if cold-rolled strip is held warm for a long time, even at moderate temperatures, Mg₂Al₃ can precipitate at the grain boundaries and cause intergranular corrosion and stress corrosion cracking.[1][2][4]
