Alluminium Alloy 5083 Angles & Flats

What are Alluminium Alloy 5083 Angles & Flats?

Alluminium Alloy 5083 is a non-heat-treatable Alluminium alloy primarily alloyed with magnesium. It is widely known for its exceptional corrosion resistance, especially in marine and saltwater environments, along with good strength and weldability.

Key Functions:

• Provide high structural strength
• Resist corrosion in marine environments
• Ensure durability under harsh conditions
• Enable efficient fabrication and welding

Chemical Composition of Alluminium Alloy 5083

Typical Composition:

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

This composition provides excellent corrosion resistance and strength.
