6000 and 7000 series aluminum alloys have poor corrosion resistance and are not suitable for marine environments. 5083 aluminum plate can be regarded as a representative product of the 5000 series marine grade aluminum plate, and the tempers include O, H111, H112, H116, H32, etc. Aluminium marine plate 5083-O has excellent strength at low temperature, such as liquefied natural gas temperatures. The material of large spherical tanks used for the transportation and delivery of liquefied natural gas, cryogenic storage tanks, liquefied natural gas is transported by ships at a temperature of minus 162 degrees Celsius, and is considered a clean energy source. The 5083 aluminium plate is widely used in LNG storage tanks. These materials must resist becoming brittle at low temperatures and be lightweight, corrosion-resistant and usable for safety during ocean transportation.

The aluminium marine plate 5083-O and other different states are mainly used in the mold manufacturing industry, shipbuilding industry and vehicle manufacturing industry, and a stable production process has been formed. The magnesium alloy content of this aluminum plate is between 4.0% and 4.9%, and the magnesium alloy content is relatively high, so the hardness and corrosion resistance are good, it can be anodized to further improve its anti-rust and corrosion resistance. Marine aluminium plate 5083 is usually used in shipbuilding and high-end equipment, so the ASTM B928 and EN573 standard must be strictly implemented to prepare the alloy ratio during production to ensure that the alloy content can meet the standard without exceeding the standard. Secondly, during annealing, it is necessary to release and relieve the internal stress, and it is also necessary to pay attention not to overburn to avoid deformation of the internal microstructure. Therefore, it is necessary to work hard to master the balance between the annealing temperature and annealing time. In terms of plate shape, attention should be paid to ensuring flatness and no scratches on the surface.

Haomei Aluminum a large-scale manufacturer of aluminium marine plate 5083-O and other tempers like H111, H112, H116 and H321. The 5083 aluminum plate produced has good gloss, good corrosion resistance, sufficient strength, good process performance and welding performance.
