Alluminium Alloy 5083 Sheets & Plates

Typical Composition:

• Aluminum (Al): Balance
• Magnesium (Mg): 4.0% – 4.9%
• Manganese (Mn): 0.4% – 1.0%
• Chromium (Cr): 0.05% – 0.25%
• Silicon (Si): ≤ 0.4%
• Iron (Fe): ≤ 0.4%
• Zinc (Zn): ≤ 0.25%

The high magnesium content enhances strength and corrosion resistance.
