Aluminum sheet, alternatively referred to as aluminum plate, is a multi - functional and lightweight substance that finds extensive application across diverse industries. Generally crafted from high - purity aluminum alloy, it exhibits remarkable corrosion resistance and durability. Aluminum sheets are available in a variety of thicknesses, spanning from thin foils to thick plates, thus enabling a broad spectrum of applications. Their easy machinability makes them perfect for fabrication procedures such as cutting, bending, and welding. Typical applications involve automotive body panels, aircraft components, and building materials.

At present, aluminum alloy is widely used in manufacturing common oil tankers worldwide, offering incomparable advantages in economic benefits, social benefits, safety, and environmental protection. Aluminum sheets applicable to tanker bodies are mainly from the 5000 series: the 5000 series is aluminum-magnesium alloy, with main grades including 5052, 5083, 5754. The most critical part of the tank body uses 5083 H111 aluminum sheet, while both sides of the tank cover adopt 5083-O state sheets (O temper is softer for bending forming), and the partition parts also use 5083-O state. Additionally, some manufacturers use 5454 H111 aluminum sheets for tank production.
Marine-grade aluminum plates primarily encompass the 5000 series and 6000 series aluminum plates, renowned for their exceptional resistance to seawater corrosion. Specific examples of marine-grade aluminum sheets include 5083, 5086, 5383, 5052, 6083, and 6061, among others. Each of these marine aluminum sheet plates serves distinct purposes in shipbuilding, catering to a variety of vessels such as luxurious aluminum yachts, sightseeing boats, fishing boats, assault boats, and patrol boats. Typically, the thickness of general marine-grade aluminum sheets ranges from 3 mm to 50 mm, with a common width of 2000 mm.
