5083 aluminum plate and 5086 aluminum plate are the main alloys of marine aluminum plate, both belong to 5 series AL-Mg alloy, and are widely used anti-rust aluminum. Because ships sail in seawater or inland rivers all year round, the requirements for anti-corrosion and other anti-rust are relatively high. These two alloys are high-magnesium alloys, which have good strength, corrosion resistance and machinability among non-heat-treatable alloys. They have beautiful surfaces after anodizing and good arc welding performance.Click to Order
In shipbuilding, 5083 and 5086 aluminum plates are often used to process multiple parts such as hulls, consoles, and decks. But the more important one is the underwater part of the hull, especially in the perennial seawater contact, the underwater part of the hull must be able to resist the corrosion of seawater and be durable for a long time. The most commonly used products in this part are 5083-H116 and 5083-H321. The ship plates in these two states have the best corrosion resistance and are more suitable for the underwater environment of the ocean than H111 and H112. Although the temperature of 5083-H116 and H321 ship plate is only slightly different during the production process, its corrosion resistance is obviously better than other states.

5083/5086 marine grade aluminum sheet has a small specific gravity, so it can reduce the weight of the ship, reduce the capacity of the single engine, increase the speed and reduce fuel consumption;It has good corrosion resistance, can reduce maintenance costs such as oiling, and can extend the service life (usually more than 20 years);It has good processing and forming performance, and is easy to perform various forms of processing such as cutting, stamping, cold bending, forming and cutting;It has good welding performance and can be welded more easily;5083/5086 marine grade aluminum sheet has small modulus of elasticity, high ability to absorb impact stress and high safety;Aluminum scrap is easily recovered and can be recycled.
Excellent corrosion resistance makes these two alloys widely used in marine applications such as ships, automobiles, aircraft weldments, subway light rails, pressure vessels that require strict fire protection (such as liquid tank cars, refrigerated vehicles, refrigerated containers), refrigeration devices, televisions Towers, drilling equipment, transportation equipment, missile parts, armor, etc.
