5456 Marine Grade Aluminum Plate Sheet

5456 aluminum plate has excellent anti-corrosion properties. Compared with 5083 aluminum plate, 5456 aluminum plate is very similar in performance but has slightly improved strength, although it is sensitive to stress corrosion.

5456 aluminum plate is mainly used for ship decks. Since 5456 aluminum plates of different hardness can meet various needs, it is widely used in different parts of ships, such as living decks, walking decks and driving decks.

Marine grade 5456 aluminum plate is used in structural applications and can be cold worked. Its strength is higher than 5086 and 5083, and it is a typical welded aluminum alloy. Typically used in bulkheads and superstructures, patrol boats and work boat hulls. 5456 is stronger than other marine grades of aluminum and is commonly used in pressure vessels and storage tanks in salt water environments.

Why choose 5456 for marine grade aluminum plate?

• 1. Corrosion resistance: Marine environments are notorious for their corrosive nature, and salt water is particularly harsh. 5456 aluminum plate/sheet has excellent corrosion resistance under these conditions, making it ideal for marine structures, ships and offshore platforms. This resistance is mainly due to the alloying elements used in its composition.
• 2. Strength: 5456 aluminum alloy has good strength properties, allowing it to withstand harsh marine environments. While not as strong as other aluminum alloys such as 5083, it is strong enough for many marine applications. The strength of the material makes it suitable for use in structural components such as hulls, masts and superstructures.
• 3. Weldability: Weldability is a critical factor in marine applications as structures often require complex fabrication and repair. 5456 Aluminum has good weldability, enabling strong and durable welded joints to be formed without compromising its corrosion resistance. Optimum results require proper welding techniques and filler materials that are compatible with 5456 alloy.
• 4. Formability: Marine grade aluminum should be easily formable to accommodate various manufacturing processes and design requirements. This property of 5456 aluminum alloy is crucial for the production of components with complex geometries, such as boat hulls and marine fittings.
