Why use aluminum sheet for ship deck?
Aluminum sheet for ship deck refers to aluminum alloy sheet used for ship deck construction. The deck is an important component of the hull, located above the inner bottom sheet, used to cover the space inside the ship and divide it horizontally into layers. The deck is composed of steel sheets and frames, which plays an important role in ensuring the strength and unsinkability of the hull, and provides an area for arranging various cabins, placing weapons and equipment, and mechanical equipment. Since ships are exposed to the marine environment for a long time, aluminum sheets for ship decks need to have excellent corrosion resistance, light weight and good mechanical properties.
Marine aluminum sheets for decks mainly use 5083 patterned aluminum sheets, 5052 patterned aluminum sheets, 5086 aluminum sheets and 6082 aluminum sheets. These aluminum sheets have high corrosion resistance and good weldability, which can meet the use requirements of ship decks in harsh marine environments. In addition, aluminum sheets for decks are also commonly used to manufacture hull structures, such as decks, bottom outer sheets, etc., to enhance the strength and stability of the hull.
Alloy series introduction:
Aluminum sheets for ship decks usually use 5000 series (such as 5052, 5083, 5754, 5454, etc.) and 6000 series (such as 6061, 6082) aluminum alloys, especially aluminum checkered sheets.
5086 aluminum checkered sheet: low density, high tensile strength, high elongation, and strong corrosion resistance. It has medium strength and good weldability. Therefore, it is widely used as marine-grade aluminum sheet.
6061 aluminum checkered sheet: 6161 aluminum sheet has excellent corrosion resistance, weather resistance, anti-slip properties, and easy processing. It is an indispensable material for making ship decks. In particular, it has no tendency to stress corrosion cracking.
5052 aluminum baffle: novel structure, good anti-slip effect, light weight, excellent durability, mass per square meter is about 7kg, tensile strength is 200N per square millimeter, relative elongation is higher than 10%, and can withstand high bending without breaking.
5086 aluminum patterned sheet: low density, high tensile strength, high elongation, strong corrosion resistance. It has medium strength and good weldability. Therefore, it is widely used as marine-grade aluminum sheet.

Main features of aluminum sheets for ship decks:
1. Corrosion resistance: Ship decks require high corrosion resistance, and 5000 series aluminum sheets are suitable for marine environments and can resist seawater erosion.
2. Lightweight: The density of aluminum alloy is one-third of that of steel. The use of aluminum sheets can reduce the weight of the hull, reduce fuel consumption, and increase speed and cargo capacity.
3. Strength and impact resistance: Aluminum sheets have high tensile strength and toughness, can withstand large impacts, and adapt to unstable marine environments.
4. Welding performance: 5000 and 6000 series aluminum sheets have good weldability and achieve good connections while ensuring structural strength.
5. High temperature resistance: Aluminum sheets maintain stable performance in high and low temperature environments and adapt to changes in sea temperatures.
6. Environmental protection: Aluminum sheets are recyclable and environmentally friendly, and the recycling cost of aluminum is relatively low, which helps to reduce the long-term cost of ship manufacturing and maintenance.
