General marine grade aluminum alloy, mostly refers to 5-series magnesium aluminum alloy. Custom plate aluminum alloy boats for sale distinguish the models according to the magnesium content, such as: 5052, 5083, etc.; simply understand that 5052 contains less magnesium and has better molding properties and is better for pressing, while 5083 contains magnesium. The high point is more brittle and hard, not suitable for pressing, but 5083 is harder than 5052 and has better corrosion resistance. 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 is used for the lower part of the boat (underwater part) and 5052 The upper part of the boat (surface part)



Custom plate aluminum alloy boats for sale material selection:
1. Outfitting also uses 5052 alloy, 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. From the perspective of hull weight reduction, thin plates are generally used as much as possible, but the depth of corrosion of the plates during use should also be considered. 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, and some special specifications are used in accordance with shipyard contracts. In order to prevent slip, the deck adopts checkered plates.
