5A05 Aluminum Coil
5A05 Aluminum Alloy: The High-Strength Marine-Grade Solution for Demanding Applications
Premium Magnesium-Alloyed Aluminum with Exceptional Performance
5A05 aluminum alloy (equivalent to AA5056) is a high-performance magnesium-aluminum alloy containing 4.8-5.5% magnesium. This non-heat-treatable alloy delivers superior strength (225+ MPa tensile) while maintaining excellent corrosion resistance in marine environments. With 15% minimum elongation, it outperforms standard 5005 alloy in structural applications requiring both strength and formability.
Key Advantages:
- Marine-Grade Durability: 0.03 mm/year corrosion rate in saltwater
- High Strength: 110 MPa yield strength in annealed condition
- Weldability: 90% joint efficiency with 5356 filler
- Cost-Effective: 20% lower than 5083 alloy

Why 5A05 Outperforms Competitors?
First, its magnesium content ensures superior strength. Second, the alloy maintains excellent weldability. Moreover, it offers cost savings versus premium alloys. Additionally, marine corrosion resistance exceeds industry standards. Finally, global availability ensures supply chain reliability.
For architectural projects, consider anodizing (20-25μm) or PVDF coatings. Industrial applications benefit from mill finish or embossing. Regardless of application, 5A05 delivers proven performance.
