5083 aluminum plate for shipboard floor

By zhangmenghao More Blogs by This Author

Ship structures are often used in harsh seawater media and marine environments, so whether or not aluminum alloys are resistant to corrosion is one of the main signs that determine whether it is a Marine Grade Aluminum. It is generally required that marine aluminum alloy substrates and welded joints have no tendency of stress corrosion, exfoliation corrosion and intergranular corrosion in seawater and marine environment; contact corrosion, crevice corrosion and sea organism adhesion corrosion should be avoided as much as possible; small uniform corrosion and points are allowed. corrosion.


Experience has shown that any small aluminum vessel can be used for decades without any significant corrosion. The decommissioning of such vessels is usually due to technical obsolescence rather than the aging of aluminum structures. In general, the excellent maritime resistance of the 5- and 6-series aluminum-magnesium alloys, especially the seawater corrosion resistance, is now recognized. Among them, the 5083 aluminum plateis a typical aluminum alloy for welding. It has the highest strength, weldability, corrosion resistance and low temperature performance in non-heat treated alloys. It can be used as a marine aluminum plate on the ship's side or the bottom of the ship.


At present, the 5083 aluminum sheetproduced by Mingtai Aluminum's 5083 aluminum sheet manufacturerhas entered the world shipbuilding market and obtained the international authority certification of China Classification Society Certificationand Norwegian Classification Society Certificationbecause of its low density and high strength. The ship side made with it can reduce the weight of the ship by more than 20%.
