Marine grade aluminum 5052

Marine grade aluminum is increasingly used in shipboard manufacturing. Due to the special environment of the ship, the craft and performance standards for marine aluminum plates are more stringent. Marine grade aluminum 5052 is such an aluminum alloy product, which can meet the requirements of corrosion resistance and high strength in the marine environment.marine-grade-aluminum-5052-1

Marine-grade aluminum 5052 performance summary

In practical applications, the advantages of marine grade aluminum 5052 are very obvious. The first is the small specific gravity, which can reduce the weight of the ship, save energy, and increase the load. Secondly, it has good corrosion resistance, reduces the cost of oiling, and extends the service life. The third is good welding and processing forming performance, which is conducive to later processing. Moreover, 5052 aluminum sheet is easy to recycle and can be recycled. At the same time, it does not burn and is safe in a fire. Of course, this is only part of the performance, the following focuses on the main performance of marine-grade aluminum 5052.marine-grade-aluminum-5052-2

Excellent corrosion resistance

Because the ship plate is immersed in seawater for a long time and the environment is humid, the ship plate is required to have high corrosion resistance and can be used in harsh seawater media and marine environments. Therefore, corrosion resistance is one of the main signs of marine alloys. Marine grade aluminum 5052 belongs to the AL-Mg series alloy gold aluminum plate, which is a typical anti-rust aluminum with very good corrosion resistance.marine-grade-aluminum-5052-3

Has high specific strength and specific modulus

The structural strength and size of ships are closely related to the yield strength and elastic modulus of the material. Since the elastic modulus and density of aluminum alloys are roughly the same, the addition of alloying elements has little effect, so the marine grade aluminum 5052 yield is increased within a certain range. Strength is effective in reducing the structure of the ship. It is usually difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. Therefore, marine aluminum alloys are generally medium-strength, corrosion-resistant, and weldable alloys.marine-grade-aluminum-5052-4

Excellent welding performance

At present, the automatic argon arc welding method is mainly used in ships. The good weldability indicates that the cracks formed during the welding of marine grade aluminum 5052 are smaller. That is to say, the aluminum plate must have good welding crack resistance because it cannot pass under shipbuilding conditions. Heat treatment again to restore the lost welding performance.marine-grade-aluminum-5052-5

Excellent processing performance

Marine grade aluminum 5052 has a good cold and hot forming properties. Because the shipbuilding has to undergo multiple treatments such as cold processing and hot processing, the marine aluminum alloy must be easy to process and shape, free of cracks, impact resistance, and still meet the strength and corrosion resistance requirements after processing.marine-grade-aluminum-5052-6Now marine grade aluminum 5052 is more and more widely used in the shipbuilding industry, and the demand is increasing day by day. Whether it is for civilian use to military use, or from fishing boats to marine mining vessels, marine grade aluminum 5052 can be used as a material for ship hulls, superstructures, various facilities, pipelines, and even appliances.
