Aluminum Aloys for Hulls
5000 Series Aluminum
5052 aluminum alloy is suitable for boat structures, auxiliary components, and small boat hulls, featuring excellent corrosion resistance, formability, and fatigue strength.
5000 Series Aluminum
A typical welding alloy among non-heat-treatable options, boasts the highest strength. Known for good weldability, corrosion resistance, and low-temperature performance, it is mainly utilized in boat structures.
6000 Series Aluminum
6061 aluminum alloy is a heat-treatable, corrosion-resistant alloy with high strength, but low weld joint strength. It is mainly used for threaded and riveted structures not in direct contact with seawater.
Outfitting Aluminum Alloys
1000 Series Aluminum
The 1050 aluminum alloy has low strength but good workability, weldability, and corrosion resistance. It boasts high surface treatment properties and is suitable for interior decoration in ships.
3000 Series Aluminum
3003 aluminum alloy has a strength 10% higher than 1100, and it exhibits good formability, weldability, and corrosion resistance.
3000 Series Aluminum
The 3203 aluminum alloy is used for ship interior decoration, top and side plates of liquefied petroleum gas tanks, as well as for manufacturing structural support components and other key parts in ship structures.
Aluminum for Boat Building
Aluminum alloys for marine use can be classified into various product types, including marine grade aluminum sheets, aluminum profiles, aluminum tubing, aluminum rods, forgings, castings, and more.
Hull structure of ship
The aluminum alloys primarily used for the hull structure of ships are 5083 aluminum, 5086 aluminum, and 5456 aluminum.
Superstructure of Ship
The 6000 series alloys are mainly used for the superstructure of ships because they are prone to intergranular corrosion in seawater.
Outfitting Aluminum
The ship outfitting primarily utilizes extruded aluminum profiles for upper ship structures, such as extruded structures and deck.
Our Aluminum Plate Hickness
The thickness of marine grade aluminum sheet used is determined by factors such as ship structure, vessel specifications, and application areas. Thinner plates are generally preferred for lightweight considerations, but the depth of corrosion during the service life of the plates should also be taken into account. Commonly provided aluminum plate thicknesses include thin plates of 1.6mm and thicker plates of 30mm and above.
Our Aluminum Plate Size
To minimize welding, 2.0m-wide aluminum plates are commonly used, while large vessels employ 2.5m-wide plates. These aluminum plates typically have a length of 6m, and we also provide special dimensions as per shipyard contracts. Patterned plates are used on the decks for slip resistance.
