5083H116 Aluminum Plate
5083 Aluminum Plate in the H116 temper is a marine-grade alloy renowned for its exceptional corrosion resistance, making it the top choice for shipbuilding and offshore structures.
Overview
5083 Aluminum Plate in the H116 temper is a marine-grade alloy renowned for its exceptional corrosion resistance, making it the top choice for shipbuilding and offshore structures.
The H116 temper is specifically designed for harsh service. It undergoes a special stabilization treatment that provides superior resistance to intergranular and exfoliation corrosion in seawater, making it ideal for critical, long-term immersed structures like hull plating and decks. It achieves an optimal balance of strength, weldability, and manufacturability.
5083 H116 aluminum sheet and 5083-H321 marine grade aluminium plate both are often used for the underwater part of the ships because of its excellent corrosion resistance.

Why Choose 5083 H116 Aluminum Plate?
The H116 temper is specifically designed for harsh service. It undergoes a special stabilization treatment that provides superior resistance to intergranular and exfoliation corrosion in seawater, making it ideal for critical, long-term immersed structures like hull plating and decks. It achieves an optimal balance of strength, weldability, and manufacturability.
5083 H116 aluminum sheet and 5083-H321 marine grade aluminium plate both 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.

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
The aluminum 5083 H116 temper is specifically designed for harsh service. It undergoes a special stabilization treatment that provides superior resistance to intergranular and exfoliation corrosion in seawater, making it ideal for critical, long-term immersed structures like hull plating and decks. It achieves an optimal balance of strength, weldability, and manufacturability
