Marine aluminum plates can be divided into deformed aluminum plates and cast aluminum plates according to different manufacturing processes. Because marine aluminum plates have special requirements for strength, corrosion resistance, weldability, etc., Al-Mg alloys, Al-Mg-Si alloys, Al-Zn-Mg alloys are the most widely used for ships.
Al-Mg alloy is the most widely used deformed aluminum alloy. It is characterized by lower density, excellent resistance to marine climate and seawater corrosion, weldability and polishability, and excellent plasticity (Mg≤5% ), as well as good seismic performance,etc. The stability of AA 5052 aluminum alloy with Mg≤3.0% is extremely high.
Marine yachts need to use 5083 aluminum plates, inland rivers use 5456 aluminum plates, and domestic park boats generally use 5052 aluminum plates. Their mechanical properties, corrosion resistance and welding properties are relatively superior, which are widely used for the keel, outer plate and hull of the ships.
The maximum magnesium content of 5052 aluminum alloy is only 2.8%, and the 5083 alloy with the highest magnesium content has a maximum magnesium content of 4.9%. Although the strength properties of the alloy increased with the increase of Mg content, the plasticity and corrosion resistance decreased significantly.
5052 aluminum plate is a special marine aluminum plate for the manufacturing of hull of yachts due to its excellent anti-rust fuction and corrosion restance to seawater and fresh water. The freshwater lake yachts generally choose 5052h32 aluminum sheet. Because it is in contact with fresh water, the corrosiveness is not as strong as that of sea water.
Haomei 5052 aluminum sheet has been certified by CCS, DNV, ABS, BV, LR,etc, is loved by the Philippines, Myanmar, Vietnam, Thailand, Indonesia and other Southeast Asian and North American shipbuilding markets. Welcome to leave message below to inquire what you need.
