5083 Marine Aluminum Plate
5083 aluminum plates are commonly used in ships, ships, automobiles and aircraft plate welding parts, pressure vessels, refrigeration devices, television towers, drilling equipment and other fields. Especially in the construction industry, it is widely used due to its good forming performance and weldability.

Overview
5083 aluminum plate belongs to the Al-Mg series alloy. It is a widely used anti-rust aluminum with medium strength, good corrosion resistance, weldability and cold workability.
5083-H116 and 5083-H-H321 marine grade aluminium plates are often used for the underwater part of the ships because of its excellent corrosion resistance.
5083 H321 aluminum plate has good corrosion resistance, machinability, weldability and medium strength.
Technical Details and Specifications
Technical description and tables retained from the original aluminum product record.
5083 aluminum plate belongs to the Al-Mg series alloy. It is a widely used anti-rust aluminum with medium strength, good corrosion resistance, weldability and cold workability.
5083-H116 and 5083-H-H321 marine grade aluminium plates are often used for the underwater part of the ships because of its excellent corrosion resistance.
5083 H321 aluminum plate has good corrosion resistance, machinability, weldability and medium strength.
After anodizing, its surface is beautiful and its arc welding performance is good. In addition, the alloy also has good cold working properties and forming properties.
Because 5083 H321 aluminum plate has the above-mentioned excellent properties, it is widely used in various fields.
In shipbuilding, it is often used to manufacture ship decks, engine mounts, ship sides, bottom outer panels and other components.
In addition, it can also be used in automobile welding parts, subway light rails, pressure vessels (such as liquid tank trucks, refrigerated trucks, refrigerated containers), refrigeration units, television towers, drilling equipment, transportation equipment and missile parts, etc.
5083-h116 and 5083-H321 aluminum plates have better corrosion resistance and are more suitable for the underwater environment of the ocean than H111 and H112 temper.
Although the temperature of 5083H116 and H321 aluminum sheets are slightly different in the production process, the corrosion resistance is significantly better than other temper.
Aluminum 5083 H321 refers to a processing method in which 5083 aluminum sheet is hardened and subjected to low temperature heat treatment, or directly heated during processing, so as to obtain stable mechanical properties
5083 marine aluminum plate is a typical Al-Mg-Si alloy with high corrosion and rust resistance. The underwater part of the hull, especially in the sea water, must be able to resist the corrosion of seawater. The most commonly used ones are 5083-H116 and 5083-H321 aluminum sheets

What are main application of 5083 aluminum plate?
Ship manufacturing: 5083 aluminum plate is one of the commonly used materials in ship manufacturing and is used to manufacture structural parts such as hulls, decks, and bulkheads.
Automobile manufacturing: Used to manufacture structural parts such as doors, hoods, and suspension systems of automobiles, helping to reduce vehicle weight and improve fuel efficiency.
Aerospace: Used to manufacture non-load-bearing structural components of aircraft, such as doors, partitions, etc., as well as non-critical components of rockets and satellites.
Construction field: used in curtain wall systems, roof and wall materials, door and window frames of high-rise buildings, etc., with good weather resistance and long service life.
Other fields: It is also widely used in pressure vessels, oil tankers, refrigerated containers, tank trucks and other occasions where corrosion resistance is required, as well as in military equipment, sporting goods and other fields.
What are difference between 5083 aluminum sheet and 5086 aluminum plate?
5086 and 5083 aluminum plates are both high-performance aluminum alloy materials with their own characteristics and application fields.
5083 aluminum plate: It has high tensile strength and yield strength, excellent corrosion resistance, especially in marine environments.
At the same time, it also has good weldability and processability, and is easy to stamp and bend.
Therefore, 5083 aluminum plates are widely used in shipbuilding, automobiles, aircraft welding parts and other fields, especially as the main aluminum material for shipbuilding.
5086 Aluminum Plate: Similar to 5083 aluminum plate, but may be slightly different in some aspects, depending on alloy composition and heat treatment status.
It also typically has high strength, excellent corrosion resistance, and good processability. 5086 aluminum plates are often used in applications that require high corrosion resistance, good weldability and medium strength, such as ship, automobile, aircraft plate welding parts, etc.
