Below is the standardized chemical composition as per EN 485 and ASTM B209 specifications commonly used worldwide:
| Element | Composition (%) |
|---|---|
| Aluminum (Al) | Balance |
| Magnesium (Mg) | 3.0 – 3.5 |
| Manganese (Mn) | 0.5 – 1.0 |
| Chromium (Cr) | 0.05 – 0.25 |
| Iron (Fe) | ≤ 0.4 |
| Silicon (Si) | ≤ 0.4 |
| Copper (Cu) | ≤ 0.1 |
| Zinc (Zn) | ≤ 0.2 |
| Titanium (Ti) | ≤ 0.15 |
Mechanical Properties & Temper Designations
The performance of the 5754 aluminum plate is influenced heavily by the temper, or hardening process, achieved mainly by cold working alongside appropriate heat treatments.
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| O | 130 – 180 | 55 – 125 | ≥ 25 |
| H22 | 190 – 255 | 110 – 160 | ≥ 10 |
| H24 | 205 – 265 | 125 – 165 | 8 – 11 |
| H32 | 220 – 275 | 145 – 185 | 6 – 10 |
