What kind of aluminum alloy is used to build aluminum alloy boats

After more and more customers understand the advantages of aluminum alloy boats, many customers prefer to consult aluminum alloy boats when buying yachts. The following are the considerations for the selection of aluminum alloy materials for aluminum alloy boats:

General marine grade aluminum alloy, mostly refers to the 5 series magnesium aluminum alloy. The models are distinguished according to the magnesium content, such as: 5052, 5083, etc.; simply understand that 5052 contains less magnesium and has better molding performance, and is better for pressing, while 5083 contains higher magnesium content, which is more brittle and hard. Suitable for profile processing, but 5083 is harder and has better anti-corrosion performance than 5052. If it is used in inland freshwater waters, use 5052. If it is used in seawater or highly corrosive waters, 5083 can be used. In order to adapt to the seawater environment and beautiful appearance, 5083 will be used for the lower part of the boat (underwater part), and 5052 for it. Upper part of the boat (surface part)

Pay attention to the choice of aluminum alloy boat material:

1. Outfitting also uses 5052 alloy, and the varieties include plates, tubes and rods

2. 5083 alloy can produce wide and thin-walled extruded profiles

3. The thickness of the plates used is determined by the hull structure, ship specifications and parts of use, etc. From the perspective of hull lightweight, thin plates are generally used as much as possible, but the depth of corrosion of the plates during the use time should also be considered. The commonly used plates are: Thin plates over 1.6mm and thick plates over 30mm. In order to reduce welding, 2.0m wide aluminum plates are often used, and large ships use 2.5m wide aluminum plates, which are generally 6m in length. Some special specifications of plates are also used in accordance with shipyard contracts. In order to prevent slip, the deck adopts checkered plates.
