5083 aluminum alloy belongs to the Al-Mg series of rust-proof aluminum alloys, which has strong resistance to seawater corrosion and good weldability and machinability. Among them, 5083 aluminum plates in H116, H321 and H112 states are widely used in the shipbuilding industry due to their different processing technology and performance characteristics.

H116 state: After special heat treatment and anti-corrosion treatment, it is suitable for structural parts in seawater environment for a long time, such as hull and deck.

H321 state: Through stabilization treatment, it can maintain excellent stress corrosion resistance after welding, and is often used in marine engineering and high-end shipbuilding.
H112 state: suitable for processing scenarios that require high plasticity, such as ship frame structures and internal support components.

Advantages of marine 5083 aluminum plate:

1. Moderate strength: Good strength performance in non-heat-treatable alloys.

2. Good corrosion resistance: It is a typical rust-proof aluminum plate that can adapt to harsh marine environments.

3. Good weldability: Good welding crack resistance, and cracks are not easy to appear during welding.

4. Good cold working performance: Easy to perform various cold working operations.

5. Low density: It can reduce the weight of the ship plate, save energy consumption, and increase the load.

Application of 5083 marine grade aluminum plate in ships:

1. Shipbuilding deck: used to construct the deck part of the ship, providing sufficient strength and corrosion resistance.

2. Engine pedestal: key parts to support and fix the engine, requiring the material to have high strength and good weldability.

3. Side and bottom outer plates: these parts are in contact with seawater for a long time, requiring the material to have excellent corrosion resistance.
