The marine grade aluminium for hull deck adopt grade of 5052, 5083 and 5083 aluminum plate with high corrosion resistance! The deck divides the ship into upper and lower parts. The part above the main deck is collectively called the superstructure; the part below the main deck is called the main hull. The long decks below the main deck are called the second deck, the third deck and so on from top to bottom. Above the main deck are short decks, which are customarily named according to the cabin name or purpose of the deck. Such as bridge deck, life-boat deck and so on.
As the marine grade aluminum alloy is used, aluminum alloy decks are also the first choice for the deck material, which not only reduces the weight, is beautiful and convenient, but also has a good anti-corrosion effect. Marine grade aluminium sheet alloy decks are generally used for 5052, 5083, 5086, 5456, 5454 aluminum plates. 5083 aluminum plates and 5086 aluminum plates are ideal marine aluminum plates for most ship manufacturers. The 5000 series belongs to the more commonly used alloy aluminum series, the main element is magnesium, and the magnesium content is between 3-5%, it can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series. Therefore, it is commonly used in aviation and shipbuilding, and it is also widely used in conventional industries.
The 5000 series aluminum alloy is a deformed aluminum alloy with Mg as the main alloying element, namely Al-Mg anti-rust aluminum alloy, 5000 series marine grade aluminium alloy is not heat-treatable and strengthened aluminum alloy.
