Marine grade aluminum sheet plate are specially treated and can be used in water or humid environments. Usually, this is done by adding special alloys to the metal to make it resistant to corrosion. Most metals, such as aluminum, have marine grade.

Structural steel has excellent mechanical properties and low manufacturing costs, and is a traditional material in the shipbuilding industry. However, more and more demand is greater, but light boats make designers look for alternative materials. Aluminum alloys are a good choice because they provide high corrosion resistance, light weight, and are considered a long-term economic development.


Aluminum alloys are generally classified according to the main alloying elements added to aluminum and the alloy’s ability to react to heat treatment and mechanical treatment. Casting aluminum alloy is made by pouring molten liquid metal into a mold of a desired shape and cooling; solid metal is mechanically deformed or forged or rolled into a desired shape to form a forged aluminum alloy.

Marine type wrought aluminum alloys generally include ag4mc aluminum-magnesium (Al-Mg) alloys and aluminum-magnesium-silicon (Al-Mg-Si) alloys. They are commonly used in structural shipbuilding, ship lifts, docks and other offshore structural applications.

Cast aluminum alloys are used in many marine applications because the casting process can create relatively complex shapes, including the superstructure of ships, structural components, internal fixtures, and various supports. They are usually aluminum silicon (Al-Si) or aluminum-magnesium alloys.

Applications of marine grade aluminum sheet plates

Boats construction ( jet boat, making boat hull, deck floor, boat seat ), steamboat, craft, aluminum panel sheet for ship building ( shipping containers ) etc

The marine grade aluminum falt plate of the present invention represents an aluminum plate, which can be applied to the shipbuilding industry and has excellent performance. Marine aluminum plate alloys are 5000 series and 6000 series aluminum alloys, represented by 5083 aluminum plates, including 5083 aluminum plates, 5086 aluminum plates, 5052 aluminum plates, 5383 aluminum plates, 5454 aluminum plates, 5456 aluminum plates, 5754 aluminum plates, 6061 aluminum plates, and 6063 aluminum plates. Aluminum plates for marines have a density Low, high strength, reduced ship weight, corrosion resistance, good durability, economy and environmental protection.

For specific applications of marine aluminum plates:

On the ship’s side, 5083 aluminum plate, 5086 aluminum plate, 5456 aluminum plate and 5052 aluminum plate can be used for the outer bottom of the ship. The marine aluminum plate has excellent corrosion resistance, can better resist the erosion of seawater, and prolong the service life of the ship.

The top plate and side plate of the ship container can be 3003 aluminum plate, 3004 aluminum plate and 5052 aluminum plate. 3003 aluminum plate has a good anti-rust effect. Under the action of long-term offshore wind and rain, the corrosion of the roof has been reduced.

The cab can be made of 5083 aluminum plate, 6N01 aluminum plate and 5052 aluminum plate. The non-magnetic aluminum plate keeps the compass unaffected and ensures the correct direction of the ship during sailing.

5052 aluminum plate is a commonly used marine aluminum plate. Pan 5052 aluminum alloy belongs to the aluminum-magnesium series alloy, which has a wide range of applications, good weldability, good corrosion resistance, good cold working performance, moderate strength, and good forming processing performance. Fatigue resistance. Due to its excellent weldability and corrosion resistance, it is very suitable for the marine environment and is an ideal material for shipbuilding.

5052 marine aluminum plate is the material of choice for high-speed ships, such as fast ferries, yachts and offshore vessels. It is widely used in the manufacture of ship sheet metal parts, bottom plates, portholes, bottom plates and side plates

The 5052 marine aluminum plate produced by our company has no peeling, bubbles, rough surface, and local mechanical damage. There are no cracks, rust spots and trace nitrate plates on the aluminum surface. Is it OK? Well, there are strict quality standards and inspection standards.

5083 aluminum plate belongs to aluminum magnesium silicon aluminum alloy. In addition to aluminum, its main components are magnesium and silicon. More than 4.0% of magnesium makes 5083 aluminum plate has excellent correction resistance and is easy to weld. By adding copper, 5083 aluminum plate has a conductivity of 28%. 5083 aluminum plate also has good forming characteristics, whether it is hot or cold worked. But hardening can only be achieved by cold working. In addition, 5083 aluminum plate has good strength, but it cannot be heat treated.

Alloy 5083 aluminum plate has higher strength and excellent thermal conductivity than 5052 aluminum plate. In the tempered state, it maintains good formability due to good ductility. It is very suitable for welding and can be hardened by cold work. Because 5083 alloy has excellent general corrosion resistance, it is used in marine applications. Because 5083 alloy can withstand extremely low temperatures without brittleness or performance loss, it is particularly suitable for the low temperature market.

5083 aluminum plate has higher strength than 5052 aluminum plate. It is known for its excellent performance in extreme environments. 5083 has strong resistance to sea water and industrial chemical environments. Its higher corrosion resistance, especially salt water corrosion resistance, makes it an excellent material for marine and processing applications. 5083 aluminum sheet performs well in extremely cold environments and will not become brittle. Easy to form, stamp and weld.

Alloy 5083 also maintains extraordinary strength after welding. It has the highest strength among non-heat-treated alloys, but it is not recommended to be used at temperatures exceeding 65°C.
