> Marine grade aluminum plate

More and more attention is paid to the lightweight of ships. Marine grade aluminum plate sheet is also used more and more in the shipbuilding process. Henan Chalco is a famous manufacturer of marine aluminum materials. We can provide a variety of certified marine products. Marine grade aluminum plate, marine grade aluminum extrusion profile, marine grade aluminum tubing, welding marine grade aluminum material, marine grade aluminum diamond plate and other products.

what is considered marine grade aluminum?

The working environment of ships requires that the hull materials have certain properties such as mechanical strength, fatigue strength, elongation and impact resistance. However, it is usually difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. Therefore, aluminum alloys for ships are generally selected to have medium-strength corrosion-resistant and weldable aluminum alloys. Therefore, Al-Mg series (5xxx series) and Al-Mg-Si series (6xxx series) are widely used as marine grade aluminum alloys, such as 5083, 5052, 5086, 6061 and so on.

what is the best marine grade aluminum

Marine grade aluminum plate 5083

Marine grade 5083 aluminum plateMarine grade 5083 aluminum plate is the most used aluminum plate in shipbuilding. It is widely used in ship structure, such as Keel of ship, ship’s rib, deck, bulwarks, ship's chimney, porthole etc.

The 5083 marine grade aluminum plate produced by Henan Chalco takes into account the structural design of the later hull, and compares and analyzes the selection of hull materials, hoping to produce a new type of ship that is safe, reliable, energy-saving and environmentally friendly. The 5083 marine aluminum plate is light in weight, wear-resistant and corrosion-resistant, which is conducive to navigation and transportation ships, and can also be used as a raw material for inland water transport hull manufacturing. In addition, the medium-thick aluminum plates of 5083 marine aluminum plates are also used in the manufacture of yachts in parks.

Features: Long width, anti-corrosion, small elastic modulus, easy to welding, easy processing, without low temperature brittleness as well as non-magnetic.

Marine grade aluminum plate 5086

Marine grade aluminum plate 5086marine grade aluminum plate 5086 is mainly alloyed with magnesium and silicon, which has excellent rust and corrosion resistance. Like 5083 marine aluminum plate, it is widely used in shipbuilding, such as Ship's side and bottom exterior board, deck.

We have a complete marine aluminum plate production line and advanced polishing technology. Our 5086 marine grade aluminum plates are smooth and uniform in brightness. At the same time, we can also customize marine grade aluminum 5086 according to customer needs.

Marine grade aluminum plate 5052

Marine grade aluminum plate 5052Compared with 5083 marine grade aluminum plate, the strength of 5052 marine grade aluminum plate is lower. In the process of shipbuilding, it is mostly used on small ships and ship structural parts, such as: cable tray on ships, porthole, Gangway, mast, etc.;

At present, the main processing technology of 5052 marine aluminum plate is through the hot rolling production line. Henan Chalco has a mature hot-rolling production line. We will provide customers with 5052 marine aluminum plates in different states according to the actual situation of the ship's hull built by the customer.

Marine grade aluminum plate 6061

Marine grade aluminum plate 60616061 marine grade aluminum plate has the advantages of good processing performance, good corrosion resistance, high toughness, no deformation after processing, easy coating, good oxidation effect, etc., and it can still maintain good operability after annealing. In particular, it has no stress corrosion cracking tendency, and its weldability and cold workability are good, and it is widely used in shipbuilding.

Marine grade aluminum plate 5754

Marine grade aluminum plate 57545754 marine grade aluminum plates are widely used in ship structures such as welded structures, storage tanks, and pressure vessels. They generally have excellent processing properties, excellent corrosion resistance, high fatigue strength, and high weldability.

No cracks, corrosion spots and traces of nitrate are allowed on the surface of the 5754 marine aluminum sheet plate. The surface is allowed to have peeling, bubbles, surface roughness and local mechanical damage whose depth does not exceed 8% of the nominal wall thickness of the part where the defect is located, but the maximum depth of the defect cannot exceed 0.5mm, and the total area of ​​the defect does not exceed 5% of the total area of ​​the plate. .

Marine grade aluminum plate 5456

Marine grade aluminum plate 5456Marine grade aluminum plate 5456 can adapt to long-term humid marine environment, has good corrosion resistance, vibration resistance, excellent low temperature performance, and the price of 5456 marine aluminum plate is relatively reasonable, and the shipbuilding cost is low. The 5456 marine aluminum alloy plate belongs to the aluminum-magnesium series of rust-proof aluminum, with slightly higher strength and stress corrosion sensitivity. It has a wide range of applications in shipbuilding, showing its superior characteristics. The choice of ship materials is of course the lighter the better.
