There are many 5083 aluminum sheet exporter in China, and after exported to other country, the application of 5083 aluminum plate is on the marine ship building. Ship structures are often used in harsh seawater media and marine environments, so whether aluminum alloys are resistant to corrosion is one of the main signs that determine whether they can be used as marine aluminum alloys. 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 marine bio-adhesion corrosion should be avoided; small uniform corrosion and points are allowed. corrosion.
Experience has shown that any aluminum vessel that has been used for decades without any significant corrosion. The decommissioning of such ships is usually due to technical obsolescence rather than the aging of aluminum structures. In general, the excellent maritime resistance of the 5000 series aluminum-magnesium alloys are recognized as the marine aluminum alloys especially in the seawater corrosion resistance. The 5083 aluminum plate is a typical welding aluminum alloy for marine application, so it is also know as marine grade aluminum alloy. 5083 aluminum 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 side. The 5083 aluminum sheet exporter has passed the DNV and ISO9001 quality-system certification, which has the ability of long using period in marine environment.
