5 series marine aluminum sheet refers to aluminum alloy sheet with magnesium as the main alloying element, which is mainly used in shipbuilding. 5 series aluminum sheet has excellent corrosion resistance and good mechanical properties, and is particularly suitable for use in humid environments such as ships.

Marine aluminum sheets are usually anodized and coated before use to enhance their corrosion resistance and anti-slip ability, extend their service life, and adapt to the high salinity and high humidity in the ship environment.

Main models of 5 series marine aluminum sheets

In shipbuilding, the commonly used 5 series marine aluminum sheet models are mainly 5052, 5083, 5086 and 5754. These models are slightly different in composition, performance and use, but all have good corrosion resistance and processing performance.

1.5052 aluminum sheet: It has excellent corrosion resistance, formability and fatigue strength, and is particularly suitable for ships, vehicles, bottle caps, and honeycomb sheets.

2.5083 aluminum sheet: It is one of the more commonly used 5 series aluminum alloys, with excellent corrosion resistance and high strength. It is widely used in shipbuilding and is often used in key parts such as hull bulkheads and hull belly sheets.

3.5086 aluminum sheet: The main alloy component is magnesium, which has good corrosion resistance, weldability and medium strength. It is mainly used for the bottom sheet of the ship, and can also be used as a material for other local parts.

4.5454 aluminum sheet: It is often used in hull bulkheads, chemical storage tanks, hull tanks and other fields, and also has good corrosion resistance and processing performance.

5.5754 aluminum alloy: 5754 aluminum alloy has high ductility and good corrosion resistance, and is suitable for hulls and decorative parts.

Features of 5 series aluminum alloy ship sheets

1. Excellent corrosion resistance: Adding alloy elements such as magnesium and silicon, it can be used for a long time in harsh environments (such as seawater).

2. Good processing performance: It has good plasticity, is easy to stamp, stretch and bend, and is suitable for processing parts with complex shapes.

3. Moderate strength: meet the material strength requirements, reduce the ship's deadweight, and improve navigation efficiency.

4. Good weldability: a variety of welding methods can be used, and the welded joints have high strength and good airtightness.

5. Lightweight: Compared with traditional steel, 5 series aluminum alloys have a lower density, which helps to reduce the weight of the hull, improve speed and fuel efficiency.

6. Environmentally friendly and recyclable: high recycling rate, in line with environmental protection and energy-saving requirements.

Application areas of 5 series marine aluminum sheets

1. Hull structure: 5083 and 5454 alloys are often used to manufacture the main structural parts of the hull, such as the outer shell, deck, etc.

2. Internal partitions and bulkheads: 5052 and 5754 aluminum sheets are suitable for partitions and bulkheads inside the ship because of their good processing performance and light weight.

3. Marine fuel tanks: 5454 is often used to manufacture marine fuel tanks and water tanks because of its good corrosion resistance to seawater and fuel.

4. Deck and passage: 5052 and 5754 are suitable for decks and passages on ships, and have sufficient durability and corrosion resistance.

Because 5 series marine aluminum sheets have excellent corrosion resistance and processing performance, they are also often used to manufacture offshore platforms, offshore oil and gas production equipment, etc.

Surface quality requirements for marine aluminum sheets

1. The surface of the aluminum sheet is free of cracks, rust, and scratches;

2. The surface color, gloss, texture, etc. are uniform and consistent, without obvious color difference or defects.

3. The surface is clean and free of dust and other impurities.
