5083 | ﹤0.25 | ﹤0.25 | 0.7-1 | ﹤0.25 | ﹤0.2 | ﹤0.15 | ﹤0.4 | 4--5.2 | 0.05 | 0.15 | Al |
Thickness(mm) | Temper | Tensile strength(Mpa) | Yield strength(Mpa) | Elongation(%) |
3-12.5 | H116 | 330-400 | ≧230 | L0=50mm: ≥10 |
12.5-50 | H116 | 330-400 | ≧230 | L0=5D: ≥10 |
3-12.5 | H321 | 330-400 | ≧230 | L0=50mm: ≥10 |
12.5-50 | H321 | 330-400 | ≧230 | L0=5D: ≥10 |
In the aluminum alloy family, 5083 aluminum alloy is favored for its excellent mechanical properties and outstanding corrosion resistance. Its main components include: aluminum (about 90%), magnesium (4.0%~4.9%), manganese (0.4%~1.0%) and other trace elements. This unique combination of ingredients enables 5083 aluminum alloy to perform well in various harsh environments.
5083 aluminum alloy plates have very high strength, especially after welding, it can still maintain excellent performance, which makes it a popular choice in shipbuilding, aerospace and construction industries. At the same time, its corrosion resistance makes it widely used in marine environments and chemical processing industries, and it can effectively resist the erosion of salt water and chemical media.
Advantages of aluminum boat hull
1. Lightweight: Aluminum alloy is a lightweight material with a relatively low density, making it suitable for yacht construction. Lightweight performance helps reduce the total weight of the yacht, improve fuel efficiency, and make it easier to handle and maneuver.
2. Strength and durability: Aluminum alloys have good strength and durability, and can withstand the impact of seawater, bad weather and sea conditions on yachts. This allows aluminum alloy yachts to provide good performance and safety in various conditions.
3. Corrosion resistance: Aluminum alloys have good corrosion resistance and are not easily eroded by seawater. This helps reduce maintenance work and extend the service life of the yacht.
4. Design freedom: Aluminum alloys have good plasticity and can be easily built into yachts of various shapes and designs. This provides designers with more freedom to create various types of yachts to meet the needs and preferences of boat owners.
