AA5005 AA5754 Hot Rolled Aluminium Sheet for Boat

04/28 2025

Features that Define AA5005 and AA5754 for Boats

1. Superior Corrosion Resistance in Marine Environments: Magnesium enhances the ionic barrier and an oxide film on aluminum surfaces, rendering both AA5005 and AA5754 highly resistant to seawater corrosion—macroscopic rustor marine corrosion that could otherwise undermine the vessel’s safety and longevity.

2. Mechanical Strength & Fatigue Resistance:

• AA5754 typically exhibits higher tensile strength (about 190 MPa after strain hardening treatments like H111 or H22) enabling it to withstand immense mechanical stress—ideal for the structural hull.
• AA5005 delivers satisfactory strength with a focus on corrosion resistance, suitable for external panels or protective coatings on sections less subject to impact.

3. Weldability and Formability: Both alloys can be welded reliably with minimal risks of stress corrosion cracking. Boat fabricators benefit from the aluminum sheets’ ability to bend, emboss, and form easily during manufacturing without structural impairment.

4. Weight Optimization: Given that aluminum is about one-third the weight of steel, transitioning to AA5005 or AA5754 hot rolled sheets for building boats champions fuel efficiency and buoyancy performance.
