Alloy 5083 aluminum plates have higher strength than 5052 plate and has exceptional thermal conductivity. In the tempered condition, it retains good formability due to excellent ductility. It is highly suitable for welding and can be hardened by cold work. Because Alloy 5083 exhibits excellent resistance to general corrosion, it is used in marine applications
Marine aluminum according to the manufacturing process can be divided into deformed aluminum and cast aluminum, due to the marine aluminum strength, corrosion resistance and weldability and other special requirements, so more choice of marine aluminum aluminum – magnesium alloy, aluminum – magnesium – silicon alloy and aluminum – zinc – magnesium alloy, wherein the 5-series aluminum – magnesium alloy most widely used in the ship, then the 5-series marine aluminum What are the characteristics of it
5-series aluminum plate 5083,5086,5456 . 6-series alloy in seawater occur inter-granular corrosion, and therefore use more upper part of the ship’s structure, 7 alloy drawback is poor corrosion resistance, and therefore limited range. On the whole, the 5 Series marine aluminum sheet is the most widely used, the most promising of aluminum products.
5 Series 5083 aluminum can be seen as representative of marine aluminum products, the state has O, H111, H112, H116, H321, etc., 5083 aluminum alloy composition: Al Al: margin silicon Si: ≤0.40, copper Cu: ≤0.10, magnesium Mg: 4.0 ~ 4.9, zinc Zn: ≤0.25 Mn Mn: 0.40 ~ 1.0 titanium Ti: ≤0.15 chromium Cr: 0.05 ~ 0.25 iron Fe: 0 ~ 0.400,5083 aluminum moderate strength, corrosion resistance and good formability, anti- higher fatigue, generally used as the main hull structure. Others such as 5052,5086,5454,5456, also is used in the hull structure or pressure vessels, piping, hull and decks.
Generally, the thickness of the sheet is determined by the structure of the hull, vessel size and use of the site, etc., from the viewpoint of lightweight hull, generally try to use thin, but should also consider the depth of corrosion in the time sheet, usually used there are more than 1.6mm thin sheet of 30mm and above the slab. Press the shipyard also has a contract to use some special specifications sheet. Non-slip, using deck checkered.
