Marine Grade Aluminium Flat Bar

 

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.

Differences between PS and CTP base plate

图片
With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,...

Introduction of aluminum foil insulation material

图片
Aluminum foil insulation material is the best thermal insulation material at present in the world. It has the advantages of light weight, low thermal conductivity, good heat resistance, aging resistance, easy combustion with other substrates, bonding does not produce droplet and other excellent properties. On the application, it is widely used in building roofing, wall, ceiling, floor, doors and windows as insulation materials. Aluminum foil itself is a good conductor of heat, directly used basically has no heat insulation, but accelerate the heat loss, so when used the insulation cotton is wrapped inside the aluminum foil . It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer. Introduction of advantages of aluminum foil insulation material: (1) Simplification of structure to avoid waste. (2) It is unnecessary to set roof exhaust system. (3) Waterproof lay...
