Application advantages of aluminum plates on ships

Application advantages of aluminum plates on ships

Aluminum plates have been used in the shipping industry for a long time, but they have been widely used in ships in modern times. Aluminum plates have low density, high toughness, high stiffness and corrosion resistance. Ship designers believe that aluminum plates are more suitable for the shipbuilding industry than thick steel plates. Advantages of the application of aluminum plates on ships: The production cost of aluminum is low, so it is more reasonable to use aluminum profiles to manufacture ships.

Specifications of marine aluminum plates

Plate Thickness: The thickness of ship aluminum plate usually ranges from a few millimeters to tens of millimeters, depending on the size and type of hull. Common thicknesses include 5mm, 8mm, 10mm, etc.

Alloys: Aluminum plates for ships usually use high-strength, corrosion-resistant aluminum alloys, such as 5 series (such as 5083, 5086) and 6 series (such as 6061, 6082 aluminum sheet) aluminum alloys. These alloys offer superior strength and corrosion resistance.

Width and Length: The width and length of aluminum panels will vary depending on the design and manufacturing requirements of the hull. Standard widths are usually between 1 meter and 2.5 meters, while lengths can be customized as required.

Surface treatment: In order to improve corrosion resistance, some marine aluminum plates may undergo surface treatment, such as anodizing, coating, etc. This helps increase the weather resistance of aluminum panels and slows down the corrosion process.

Certification and standards: Aluminum plates for ships usually need to comply with specific certification standards, such as the regulations of the International Maritime Organization (IMO), certification by classification societies (such as DNV, LR, ABS, etc.).

Advantages of aluminum plate application on ships

• 1. Due to the low density of aluminum plates, the net weight is lighter than other materials. The overall net weight of ships made of aluminum plates is about 15 to 20% lighter than ships made of thick steel plates. In this way, designers can reduce the volume of a single engine. Increase the sailing speed; the fuel consumption will also be greatly reduced. Ships made of aluminum materials are more reliable, easier to operate, and have higher transportation capacity.
• 2. The corrosion resistance of aluminum plates reduces maintenance costs such as oiling and can extend the service life (usually more than 20 years).
• 3. The processing and forming performance is good, which is convenient for cutting, stamping, cold-formed steel, forming and cutting and other types of processing. It is suitable for the streamlined hull; it can extrude large and medium-sized wide and thick-walled aluminum profiles. Reduce the number of welds and make the hull structure rational and lightweight.
• 4. The welding performance is good and the welding can be carried out relatively easily. The elastic mold is small, has a large ability to absorb impact internal stress, and has a high reliability factor. It has no ultra-low temperature ductility and is most suitable for ultra-low temperature equipment.
• 5. Aluminum waste is easy to recycle and can be recycled. Because it is non-guided, the Feng Shui compass is not affected. All-aluminum ships can prevent mine attacks and are suitable for use as minesweepers.

From the perspective of ship designers, the advantages of aluminum plates in ships are that ships made of aluminum alloy profiles can achieve better efficiency and longer service life. This advantage of aluminum alloy profiles makes it more suitable for use in ships. With the rapid development of aluminum plate manufacturers, the shipping industry has provided a wide range of applications for aluminum profiles.

Specific applications of aluminum plates in ships

Aluminum sheets have many applications on ships, mainly due to their excellent performance and characteristics. The following are some common applications of aluminum plates in the marine field:

Hull structure: Aluminum plates are often used in the construction of hull structures, especially on light ships and high-speed craft. Aluminum has a lower density and superior strength, allowing the hull to be lightweight but still have sufficient structural strength.

Hull Shell: Aluminum sheets can be used to construct the hull shell, providing good corrosion resistance. This is very important for ships in marine environments, as the salt and humidity in seawater can have a corrosive effect on metal materials.

Deck and Superstructure: Lightweight yet strong aluminum panels are also commonly used on ships’ decks and superstructures to reduce overall weight and improve vessel stability.

Marine equipment and components: Aluminum alloy can be cast or processed to form and used to manufacture various marine equipment and components, such as marine ladders, railings, masts, ladders, etc.

Cargo holds and storage equipment: In some specific types of ships, aluminum sheets are also used to manufacture cargo holds and storage equipment. Its lightweight nature has a positive effect on improving freight efficiency and reducing fuel consumption.

Marine bulkheads: Aluminum alloy plates can also be used to build bulkhead structures on ships to ensure that water does not quickly enter the entire hull in the event of an accident.
