5052 marine grade aluminum sheet plate
5052 marine grade aluminum sheet plate is a high-quality, medium-strength alloy extensively used in marine and transportation environments due to its superior corrosion resistance and excellent weldability. Composed primarily of aluminum alloyed with magnesium, 5052 aluminum exhibits excellent formability as well as outstanding resistance to saltwater corrosion, making it ideal for harsh maritime and coastal applications.
Chemical Composition
| Element | Composition (%) |
|---|---|
| Aluminum (Al) | Balance |
| Magnesium (Mg) | 2.2 – 2.8 |
| Chromium (Cr) | 0.15 – 0.35 |
| Manganese (Mn) | ≤ 0.10 |
| Iron (Fe) | ≤ 0.40 |
| Silicon (Si) | ≤ 0.25 |
| Copper (Cu) | ≤ 0.10 |
| Zinc (Zn) | ≤ 0.10 |
| Titanium (Ti) | ≤ 0.03 |
Features
1. Excellent Marine Corrosion Resistance
5052 aluminum is particularly suited to salinated or marine environments due to its magnesium content, which significantly improves resistance against seawater and salt spray corrosion.
2. High Strength
Compared to other aluminum alloys such as 1100 or 3003, alloy 5052 provides better strength and durability while maintaining enhanced workability.
3. Good Weldability
This grade is well-suited for welding using standard commercially available methods including TIG, MIG, and spot welding without losing its structural integrity.
4. Outstanding Formability
5052 aluminum sheet plates can be easily bent, stamped, pressed, and formed, helping accommodate curved or dimensional marine structures with ease.
5. Non-Magnetic and Non-Toxic
Contributing to excellent user safety where wireframes and paneling are fabrications, 5052 aluminum is non-magnetic, making it ideal for electrical enclosures or electronics cabling components in marine settings.
6. Improved Fatigue and Wear Resistance
Its resistance to mechanical stresses assures a longer service life in highly dynamic and demanding environments.
