High quality 3mm, 4mm, 5mm, 8mm 5083 H116/H321/H112 aluminum plates for ships, DNV/CCS certified sheets

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.

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.

Parameters:

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.

DNV certification: DNV (Det Norske Veritas) is an internationally renowned classification society, and its certification indicates that the plates meet international maritime standards and specifications.

CCS certification: CCS (China Classification Society) is the China Classification Society, and its certification indicates that the plates meet the relevant requirements and standards of the China Maritime Safety Administration.

5083 H116/H321/H112 aluminum plates are DNV/CCS certified, which means that these plates have passed rigorous testing and audits, meet international and domestic maritime standards, and are suitable for shipbuilding.
