The price of marine grade aluminium sheet used in shipbuilding varies greatly, which is related to the thickness, alloy, temper, quality and other factors of the product. The price of marine aluminum sheet is not easy to determine, and a more accurate quotation needs to be integrated in various aspects. Therefore, the user needs to know the information and find the aluminum sheet manufacturer's professional to give a more detailed quotation based on the actual situation. Most of marine grade aluminum sheet use the 6-8 mm shipbuilding aluminum plate with 5083 and 5086 aluminum plates. This product has many specifications, tempers, and a wide range of thicknesses, which can meet the actual needs of users.

Before telling the price of marine grade aluminum sheet, we should know the specification of marine aluminum plate first.

Alloy: 5083, 5086, 5052, 5059, 5454, 5383

Thickness: 3-50mm

Width: 20-2650mm

Material status: O, H32, H111, H112, H114, H116, H321, etc.

Performance characteristics: high strength, low density, strong corrosion resistance, durable, easy to process, flat surface, economical and environmentally friendly, and high recyclability.

Aluminum sheet for shipbuilding are mainly aluminum-magnesium series alloys, aluminum-magnesium-silicon series alloys and aluminum-zinc-magnesium series alloys. According to the location used, they are divided into aluminum alloys for upper outfitting and aluminum alloys for hull structures. The equipment includes masts, portholes, chimneys, wheelhouses, etc. The hull structure includes bulkheads, floors, keels, bottom shells, and ship sides. The commonly used marine grade aluminum sheet alloy profiles for portholes in the superstructure of ships are 6063 aluminum alloys, and 6063 and 6061 aluminum alloys are often used for masts and gangways. In addition, the use of extruded aluminum-magnesium alloy for the wall plate can prevent deformation during welding and ensure a more reasonable stress distribution. In the hull structure, the application rate of aluminum-magnesium alloys is relatively high, among which 5454 and 5083 aluminum alloys are the main materials for manufacturing decks.

Although the price of marine aluminum sheet is higher than ordinary aluminum sheet, it is still hot and needed in shipbuilding industry. The product application advantages of marine grade aluminum sheet are:

1, Excellent welding performance:

It has good welding crack resistance, and the performance of welded joints after welding is not much different, so it is very conducive to shipbuilding welding;

2, Excellent corrosion resistance:

Alumina film and anodic oxidation technology can maintain a very stable form in seawater;

3, Low density:

Light, which is conducive to the increase of the maximum speed of the ship and the fuel economy, so as to obtain a longer cruising range with the same amount of fuel.
