What Are Advantages of Marine Grade Aluminium 5083
Marine grade aluminum 5083 features high strength, corrosion resistance, plasticity and excellent welding performance in the shipbuilding industry. In the 1960s, it has been widely used to make yacht shells, hull superstructures, masts and port infrastructure. In the 1970s, high-speed aluminum passenger ships appeared in Scandinavia for the first time. With their speed and economic advantages, aluminum ships once became a model in the field of passenger ships.
Ship structures are mostly used in harsh seawater media and marine environments, so whether aluminum alloys are corrosion resistant is one of the main signs that determine whether they can be used as marine grade aluminum.
Generally, marine aluminum alloy sheet and welded joints are required to be free from stress corrosion, spalling corrosion and intergranular corrosion in seawater and marine environments. Contact corrosion, crevice corrosion and marine adhesion corrosion should be avoided as much as possible.
Among them, 5083 aluminum plate is a typical welding aluminum alloy with medium strength, good weldability, corrosion resistance and low temperature performance. It can be used as a marine aluminum plate on the side of the ship.
The working environment of ships requires structural materials to have certain properties such as mechanical strength, fatigue strength, elongation and impact resistance. The side and bottom outer plates of ships require high corrosion resistance. Generally, 5083 aluminum sheets are used. The common tempers are 5083 H116/H321/H112. Haomei 5053 aluminium sheets have been successfully used on yachts, cruise ships and other ships.
For example, Haomei 5083 aluminum plate with thicknesses of 4mm and 5mm are generally used for the upper part of ships. 6-8 mm thick aluminum sheets are mainly used for engine bases, and 10-12mm thickness is mainly used for underwater parts. Haomei 5083 aluminum enjoys high reputation because of superior performance and stable performance.
5083 aluminum plate is also widely used for the keel of ships. The keel is a longitudinal member that connects the bow post and the stern post in the center of the base of the hull. It is located at the bottom of the ship and is usually the first part of the ship to be built. Welcome to leave message below to inquire it.
