Marine aluminum is a necessary material for shipbuilding. For shipbuilding enterprises, with excellent corrosion resistance, stable supply of aluminum alloy ship plate, is extremely important. In this year the domestic aluminum market, with excellent performance of Henan Chalco 5083 marine grade aluminum plate, the scale of production strength, conquered many foreign shipbuilding enterprises.  
There are several types and uses of marine grade aluminium sheet. Here are some of the main marine aluminium sheet. 7075 marine grade aluminum plate, Its good corrosion resistance and oxidation resistance, it also has good, easy to process and wear resistance, and availability is also good. At 150 degrees below, there is a high strength, and has a particularly good low temperature strength, poor welding performance, stress corrosion cracking tendency, two stage aging can improve the performance of SCC.
6061 marine grade aluminum plate has excellent processability, excellent welding characteristics and electroplating, good corrosion resistance, toughness, easy polishing, color film, excellent oxidation effect. The main alloying element in 5083 marine grade aluminum plate alloy is magnesium, which has good corrosion resistance and weldability, and medium strength. Good resistance to corrosion of the 5083 alloy is widely used in marine applications such as ships, aircraft and automotive, welding parts, light rail, pressure vessels need strict fire (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration equipment, television tower, drilling equipment, transportation equipment etc. In non heat treatable alloys, good strength, corrosion resistance, good machinability. After anodizing, the surface is beautiful. It can be machined into optical mechanical components. Marine parts and wire clips.  
In addition, there are 2024 marine grade aluminum plate and 1060 marine grade aluminum plate and so on many kinds of marine aluminum plate.
