For more detailed information including pricing, customization and shipping.
Due to the harsh marine environment where ships work, marine aluminum plates must be able to withstand the corrosion of seawater, electrochemistry, marine organisms and microorganisms. The construction and working environment of ships require aluminum to have good corrosion resistance, weldability, plasticity, and certain tensile strength, yield strength, elongation, impact resistance and other properties. The use of aluminum to build ships not only saves resources and protects the environment, but also helps to reduce the weight of transportation vehicles.
Marine grade aluminum plates are mainly 5xxx and 6xxx series aluminum alloys, especially 5083 aluminum sheet plate, 5086 aluminum sheet plate, 5454 aluminum sheet plate, 5754 aluminum sheet plate, 5052 aluminum sheet plate and 6061 aluminum sheet plate. Common tempers are H111, H112, H321, H116, etc. Marine grade aluminum sheets plates are mainly used in ship decks, engine pedestals, ship sides, bottom outer plates and other components. Our marine aluminum plates have passed CCS, DNV, BV, ABS classification certifications. The product's mechanical properties, welding performance and corrosion resistance are up to the ship standards.
5083 Marine aluminum sheet plate: 5083 aluminum plate is the strongest non-heat treatable aluminum alloy that maintains its strength even after welding, has high strength and low ductility fracture properties and is highly corrosion resistant and good anti-rust function, can resist the corrosion of the hull by sea water, marine climate and harsh environments, reduce maintenance costs such as oiling, is great significance to the safety and life of ships. 5083 marine aluminum sheet plate is mainly used for decks, engine bases, ship sides, bottom outer plates, keels, and hull structural materials. The common tempers of 5083 aluminum sheet plate for shipbuilding are O, H111, H112, H116 and H321. 5083-H116 and 5083-H321 aluminum sheets plates have better corrosion resistance and are more suitable for the marine underwater environment than H111 and H112 tempers.
5086 Marine aluminum sheet plate: 5086 aluminum plate is a typical anti-rust aluminum, which is widely used in occasions that require high corrosion resistance, good weldability, and medium strength, such as weldable parts for ships and automobiles. 5086 aluminum sheet has high electrical conductivity and excellent corrosion resistance. 5086 aluminum sheet can be strengthened by strain hardening and cold working until it is stronger than 5083. While 5086 aluminum sheet is compatible with several welding methods, arc welding is the alloy of choice. 5083 and 5086 aluminum plates are commonly used in ship hull structures and decks, ship sides, bottom outer plates, etc. 5086 aluminum plate for the ship can achieve energy saving, emission reduction and improve ship performance.
5052 Marine aluminum sheet plate: 5052 aluminum plate is a common marine grade aluminum plate. It has excellent weldability, good corrosion resistance, cold workability, medium strength, good formability and fatigue resistance; is suitable for manufacturing economical aluminum ships. 5052 Marine grade aluminum plate is the material of choice for high-speed ships such as fast ferries, yachts and offshore work boats. It is widely used in the manufacture of ship sheet metal parts, bottom plates, portholes, bottoms, and side plate of shipbuilding containers. 5052-H32 aluminum sheet plate and 5052-O aluminum sheet plate for small freshwater lake yachts hulls, because fresh water is not as corrosive as seawater.
5454 Marine aluminum sheet plate: 5454 aluminum plate has very good corrosion resistance, rust resistance and weldability, especially to seawater and general environmental conditions. 5454 Aluminum plate is a non-heat-treatable alloy that can be strengthened by cold working. Its strength is 20% higher than medium-strength 5052 aluminum plate. 5454 Marine grade aluminum and 5083 marine grade aluminum are sister alloy, has lower stress corrosion levels when operating in the 150°F to 300°F range. It has excellent anti-rust properties, high fatigue strength and excellent weldability. 5454 Aluminum sheet plate is usually used in environments with high rust prevention requirements, such as marine facility pipelines, aluminum tank car bodies, automobile wheels, ships and other welded structures. The commonly used alloy is 5454-H32 aluminum plate.
5754 Marine aluminum sheet plate: 5754 aluminum sheet is a low magnesium marine aluminum alloy used in the shipbuilding industry, has superior corrosion resistance, good weldability and moderate strength, and is ideal for marine industry and other industrial applications with corrosive operating environments. 5754 Aluminum alloy is stronger than 5251. This high strength makes 5754 aluminum sheet plate ideally suited for marine applications requiring a combination of strength and resistance to seawater corrosion. 5754 Marine grade aluminum plate is commonly used in shipbuilding, marine applications, finishing industry equipment. The common tempers of 5754 aluminum sheet plate are H22, H32, H111.
