Karatasi ya alumini ya daraja la baharini is specially treated to withstand use in water or wet environments. Kwa kawaida, hii inafanywa kwa kuongeza aloi maalum kwa chuma ili kuifanya sugu ya kutu. Metali nyingi, kama vile alumini, kuwa na alama za baharini.
Structural steel is the traditional material used in the shipbuilding industry due to its excellent mechanical properties and low manufacturing costs. Hata hivyo, the increasing demand for larger, yet light ships made designers search for alternative materials. Aluminum alloys were a great choice because they provided high corrosion resistance, weighed less, and were considered economical in the long run.
Hot sale alloy temper: 5052, 5083

Types of Marine Grade Aluminum Alloys
Aluminum alloys are generally classified according to the primary alloying element added to aluminum and the alloys' ability to respond to thermal and mechanical treatment. Cast aluminum alloys are formed by pouring molten liquid metal into molds of requisite shapes and cooled; solid metal is mechanically deformed or forged or rolled to the required shape to form wrought aluminum alloys.
Marine grade wrought aluminum alloys usually comprise aluminum-magnesium (Al-Mg) alloys and aluminum-magnesium-silicon (Al-Mg-Si) aloi. They are generally used in structural shipbuilding, boat lifts, docks, and other offshore structural applications.
Cast aluminum alloys are used in numerous marine applications because casting processes can create relatively complex shapes, including ships' superstructures, vipengele vya muundo, interior fixtures and various supports. They are usually aluminum-silicon (Al-Si) or Al-Mg alloys.
The marine grade aluminum sheet stands for the aluminum sheet can be applied to the marine industry with good performance. The marine aluminum sheet alloy are 5000 mfululizo na 6000 mfululizo wa aloi ya alumini, represented by 5083 sahani ya alumini, ikijumuisha 5083 sahani ya alumini, 5086 sahani ya alumini, 5052 sahani ya alumini, 5383 sahani ya alumini, 5454 sahani ya alumini, 5456 sahani ya alumini, 5754 sahani ya alumini, 6061 sahani ya alumini, 6063 sahani ya alumini, na kadhalika. The features of marine aluminum plate are low density, nguvu ya juu, ship weight reduction, upinzani wa juu wa kutu, kudumu, economical and environmental protection.
To the specific application of marine grade aluminum sheet:
On the ship’s side, the outer bottom plate of the ship can be made of 5083 sahani ya alumini, 5086 sahani ya alumini, 5456 sahani ya alumini na 5052 sahani ya alumini. The excellent corrosion resistance of the marine aluminum sheet can better resist the erosion of sea water and prolong the life of the ship.
The top and side plates of the marine ship container can be made of 3003 sahani ya alumini, 3004 sahani ya alumini na 5052 sahani ya alumini. The 3003 aluminum plate has good anti-rust effect. Under the long-term sea wind and rain, the rust of the top plate is reduced to some extent.
The wheelhouse can be made of 5083 sahani ya alumini, 6N01 aluminum plate and 5052 sahani ya alumini. The non-magnetic plate of the aluminum plate makes the compass unaffected and ensures the correct direction of the ship during navigation.
