5052 H32 Aluminum Sheet

5052 H32 aluminum sheet is an Al-Mg series rust-proof aluminum alloy, famous for its balance of strength, formability, and corrosion resistance.

5052 H32 aluminum alloy is renowned for its excellent corrosion resistance, moderate strength, good formability, and superior weldability, making it one of the preferred materials in the marine and shipbuilding industries. It is especially suited for hull plating, internal structures, liquid storage systems, and corrosion-resistant hardware components. Its overall performance ensures long-term service life and reliability in harsh marine environments.

5052-H32 aluminum sheet is a high-strength, non-heat-treatable alloy, known for its excellent corrosion resistance, especially in marine and industrial environments. The "H32" temper indicates that the material has undergone strain hardening and stabilization treatment, which enhances its strength and machinability.

5052 H32 aluminum sheet is known for its excellent fatigue strength, good weldability, and corrosion resistance, making it particularly suitable for marine environments and vehicle manufacturing. Haomei Aluminum has an annual production capacity of 1 million tons and supports custom specifications with extra-wide (2650mm) and extra-thick (600mm) options.

5052 H32 Aluminum Sheet Typical Applications

5052 H32 Aluminum in Marine Applications

Hull Structure

Application: Used for manufacturing hulls, deck plates, and sidewall structures for small and medium-sized boats.

Advantages:

Excellent resistance to seawater corrosion: 5052 alloy contains magnesium (Mg), which provides strong resistance to chloride corrosion, making it ideal for long-term exposure to marine environments.
Moderate strength: Compared to higher-strength 7xxx or 2xxx series aluminum alloys, 5052 is easier to process into complex structural shapes, making it suitable for small and medium boat structures.
Good weldability: Can be welded using TIG, MIG, and other methods without special treatment, providing high structural integrity.

Ship Flooring

Application: Used for flooring in ship interiors, corridors, cockpit areas, and deck working areas.

Advantages:

Lightweight: The density is only 2.68 g/cm³, which helps reduce the overall weight of the hull and improve fuel efficiency.
Wear and corrosion resistance: Performs well even in high humidity and salt mist environments, remaining corrosion-free for many years.
Excellent compatibility with surface treatments: Can be anodized, slip-resistant treatments are available, improving durability and aesthetics.

Fuel Tank Systems
