Marine grade aluminium flat bar is an aluminum parallelogram bar cut from marine grade aluminium, which is widely used in shipbuilding due to its advantages of lightweight, corrosion resistance, easy processing, etc. The aluminum grades of marine grade aluminum flat bar are 5000 series and 6000 series, including 5052, 5083, 5086, 6061 and so on. 5083 marine grade aluminum alloy is an aluminum-magnesium alloy, typical rustproof aluminum grade, whose corrosion resistance, processability, strength, etc. are in line with the requirements of marine aluminum processing, and is therefore widely used in the superstructures and upper devices, such as masts, chimneys, gun mounts of gunships, lifting devices and so on. This kind of marine grade aluminium bar has a series of excellent performance characteristics, which makes it occupy an important position in shipbuilding.

Materials and specifications of marine grade aluminium flat bar:

The material of marine grade aluminum flat bar is usually 5000 series aluminum alloy, indicating and magnesium element aluminum. According to different application scenarios and requirements, different materials of marine aluminium flat bars have corresponding specifications.

1. Dimensions

The thickness of marine grade aluminum flat bar is generally 0.2 - 8.0mm, the width is generally 20 - 600mm, and the length is generally 1000 - 6000mm, of which the more common specifications are 1.0 × 20 × 2000mm, 1.0 × 30 × 2000mm, 1.0 × 40 × 2000mm, 1.0 × 50 × 2000mm, and so on.

2. Surface treatment

Marine grade flat aluminum bars generally need surface treatment, common anodic oxidation, electrophoretic coating, electrostatic spraying and other treatments. These treatments can improve the surface performance of flat aluminum bar, improve its corrosion resistance and corrosion resistance, so that it has better stability and durability in different environments.

5083 marine grade aluminium flat bar is an important material commonly used in shipbuilding. This kind of flat aluminum bar is mainly made of 5083 aluminum alloy, which belongs to the aluminum-magnesium alloy and has a series of excellent performance characteristics, especially suitable for shipbuilding field.

First, 5083 aluminum alloy has excellent corrosion resistance, especially in seawater environment. This enables 5083 marine grade aluminum flat bars to effectively resist the erosion of seawater, ensuring the durability of ship components and reducing maintenance frequency and costs.

Secondly, 5083 marine grade aluminum bar has good workability and formability. It can be shaped by cutting, stamping, cold bending and other processing methods to meet the needs of various complex shapes and structures in shipbuilding. At the same time, its excellent welding performance also facilitates the connection with other components to improve the stability and safety of the overall structure.

In addition, the flat aluminum bar is also characterized by high strength and light weight. The high strength makes it able to withstand the various forces that a ship may encounter during navigation, while the lightweight feature helps reduce the weight of the hull and improve the ship's navigation speed and fuel efficiency.

In shipbuilding, marine grade aluminium flat bar is commonly used in the manufacture of hull structures, decks, masts and other components. Its excellent performance characteristics make the ship more robust and durable, and also help to improve the safety and sailing efficiency of the ship. Overall, marine grade flat aluminum bar is an indispensable and important material in shipbuilding, and its excellent performance and wide range of applications make it occupy an important position in ship manufacturing.
