5083 marine grade aluminium sheet 4x8 is the main alloy of aluminum plate for ships and the main aluminum material for shipbuilding. With the development of lightweight technology, more and more ship companies have begun to adopt aluminum alloy materials. In modern times, they are mostly steel and aluminum and other composite materials. Because ships sail in sea water or inland rivers all year round, the requirements for anti-corrosion and rust prevention are relatively high. The most commonly used are 5083 H116 aluminum plate and 5083 H321 aluminum plate, the corrosion resistance of the marine grade aluminum plate in these two temper is the best.

The marine grade aluminium sheet 4x8 for ships is a high-magnesium alloy, which is Al-Mg 5000 series anti-rust aluminum, with high strength and corrosion resistance stability, and good plasticity in the annealed and extruded state. The air tightness and plasticity of the welds made by argon arc welding are acceptable. The strength of the welded joints of gas welding and spot welding is 90-95% of the basic strength, and the machinability is good. Using acid detergent to clean the surface of 5083 marine grade aluminium sheet can not only improve the gloss and brightness of the aluminum plate, but also has a good repair effect on the surface performance of the marine grade aluminum plate, which can meet the needs of customers with strict requirements on the surface of the aluminum plate.

Haomei Aluminum is a leading marine grade aluminium sheet 4x8 manufacturer in China with advanced technology and equipment and mature technology. The surface of its marine grade aluminum sheet for ships has no oil spots, no waves, no scratches, no roll marks, neat trimming, and no burrs. The performance of the marine grade aluminum plate is equivalent to that of foreign materials, and the performance is excellent. It has obtained domestic and international marine aluminum sheet material certification, and the product has opened up a broad international market with its excellent quality and stable performance.
