Typical Chemical Composition of 5052 Alloy
5052 is an Al-Mg alloy. Magnesium is the primary alloying element, with small additions of chromium and traces of other elements to stabilize grain structure and enhance performance.

|---|
| Al | Balance | Balance | Base metal; provides low density and natural oxide film |
| Mg | ~2.5 | 2.2 – 2.8 | Increases strength, improves corrosion resistance |
| Cr | ~0.20 | 0.15 – 0.35 | Controls grain structure, enhances toughness and corrosion behavior |
| Fe | ≤ 0.40 | ≤ 0.40 | Impurity; controlled to maintain ductility and surface quality |
| Si | ≤ 0.25 | ≤ 0.25 | Impurity; excessive levels reduce formability |
| Cu | ≤ 0.10 | ≤ 0.10 | Impurity; higher copper reduces corrosion resistance |
| Mn | ≤ 0.10 | ≤ 0.10 | Minor solid-solution strengthening |
| Zn | ≤ 0.10 | ≤ 0.10 | Minor impurity; little effect at low levels |
| Others | ≤ 0.05 each | ≤ 0.05 each, ≤ 0.15 total | Tightly controlled to ensure consistent properties |
