Marine aluminum alloy sheet most use Al-Mg series and Al-Mg-Si series alloys are the most used and have good effects. The alloy of marine aluminum sheet are 5052, 5053H116, 5083H321, 5086, 5A06 aluminum plates, etc. For example, a ship uses aluminum 5.6 and 8 mm thick 5083 aluminum alloy sheet, 10 and 14 mm thick 5052 aluminum alloy plate, round head flat aluminum of 5A06 alloy, some aluminum alloy castings. The installation of the superstructure is riveted to the steel deck with 5A05 alloy rivets and measures are taken to prevent contact corrosion. The superstructure of the ship is about 100 tons of aluminum, which is 50% lighter than steel. The overall weight of the boat is reduced by 12% and the center of gravity is raised by 15 cm, significantly improving the stability of the boat. Al-Zn-Mg alloys are also of increasing interest.
Use of marine aluminum alloy sheet are:
1, Aluminum alloys are used for hull construction. The superstructure and upper devices of various types of ships (masts, chimneys, gun mounts of gunboats, lifting devices, etc.) are more and more inclined to use 5083 aluminium alloys. The use of aluminum in the superstructure is a wide extruded siding.
2, Aluminum alloy for outfitting.
The advantages of marine aluminum alloy sheet are:
1, Aluminum has obvious weight reduction effect, energy saving effect and environmental protection effect, which helps to improve the balance, comfort and safety of transportation vehicles. key material.
2, The application scope and proportion of aluminum materials in rail vehicles, automobiles, ships, ships and containers are increasing day by day, and all-aluminum modern transportation tools have emerged in large numbers. The transportation industry has become a major user of aluminum materials, and the rapid development and wide application of aluminum materials are partially replacing steel as the basic material of the transportation industry.
