Large Aluminum Sheets for Shipbuilding
Aluminum alloys are of low density, large specific elastic modulus and high specific strength, and it is relatively low in price and good in manufacturability. Moreover, the weight of aluminum alloy ships is more than 15% lighter than that of steel ships, so it is an ideal material for building high-speed ships. The large aluminum sheets like 2*4m, 2*6m, 2*8m and 2*10m are very suitable for shipbuilding.
In the ship design industry, 5083 large aluminum sheets in the state of 5083H116/H321/H112 are mostly used. 5083H111 and 5083H112 belong to the same 5083 aluminum alloy, the two are essentially the same, and there is no difference in chemical composition. The alloy used for marine application is mostly 5083h111 marine aluminum plate.
5086 aluminum sheet, with a magnesium content between 3.5% and 4.5%, is a high magnesium and non-heat treatable alloy. Therefore, the strength of 5086 aluminum alloy is higher than that of 5052 aluminum alloy, but the strength is slightly lower than that of 5083 aluminum alloy. It is well used on both sides of ships, decks, tankers, pressure vessels and transportation equipment. Generally speaking, the state of commonly used 5086 marine aluminum plate is O, H111, H112, H116, H321, etc.
The anti-rust function and corrosion resistance of aluminum alloy 5052 can well deal with the corrosion of seawater, fresh water, etc. This is also an important reason why the 5052 marine aluminum plate is applied to the hull. The width of Haomei 5052 aluminum plate can reach 2650mm. In recent years, its usage has been relatively large. Aluminum alloy yachts for freshwater lakes are mostly made of 5052-H32 or 5052-O aluminum plates.
The welding of aluminum alloy ships is the focus and difficulty of its construction. In actual construction, welding equipment with small deformation and high efficiency should be used. Among them, the commonly used welding processes include melting pole automatic/semi-automatic argon arc welding MIG and tungsten electrode automatic argon arc welding TIG.
In the market of marine aluminum sheet products, classification societies require manufacturers to strictly abide by the normative standards in the marine field and the rigorousness of laboratory inspection qualifications, and only allow enterprises to enter the marine industry after certification with almost strict requirements. Haomei Aluminum’s marine grade aluminum sheets have got the certification of DNV, ABS, LR, RINA, CCS,etc. Welcome to leave message below to inquire what you need.
