Product Details
5052 aluminum sheet is a popular Al-Mg alloy from the 5000 series, well-known for its excellent corrosion resistance, moderate strength, and good formability. It is widely used in marine, transportation, and industrial applications where durability and resistance to environmental factors are important.
Chemical Composition of 5052 Aluminum
| Element | Content (%) |
|---|---|
| Aluminum (Al) | Balance |
| Magnesium (Mg) | 2.2 – 2.8 |
| Chromium (Cr) | 0.15 – 0.35 |
| Iron (Fe) | ≤ 0.4 |
| Silicon (Si) | ≤ 0.25 |
| Copper (Cu) | ≤ 0.1 |
| Manganese (Mn) | ≤ 0.1 |
| Zinc (Zn) | ≤ 0.1 |
| Titanium (Ti) | ≤ 0.03 |
Composition Highlights
Magnesium (Mg): Enhances corrosion resistance, especially in marine environments
Chromium (Cr): Improves structural stability and prevents stress corrosion cracking
Low copper and silicon content: Maintains good weldability and formability
