ABS Marine Certification 5052 Aluminum Sheet
Aluminum sheet for the freshwater yachts mostly chooses 5052-H32 or 5052-O aluminum alloy while luxury yachts on the sea are generally made of high-magnesium alloy 5083H116 or 5083H321 aluminum plates. The chosen 5052 aluminum sheet thickness is generally 3-30mm, and the thickness below 12mm is more widely used, and the size is generally 2000*8000mm and 1500*6000mm.
The American Bureau of Shipping (ABS) "Factory Approval" certificate is the "entry card" for Haomei Aluminum to enter the marine aluminum plate market, marking that the aluminum sheets produced by Haomei Aluminum meet the specifications of the American Bureau of Shipping, and the production of aluminum sheet has perfect quality assurance system and stable production capacity.
The American Bureau of Shipping has strict requirements for the qualification of the enterprise. The declaring enterprise must have complete production equipment, complete production capacity, establish a quality management system and operate it effectively, and pass the ISO9001 certification. We make it.
Although 5052 aluminum is easier to form, 5083 can provide about 1.5 times the tensile and yield strength. Tensile strength is the maximum stress a material can withstand before being pulled apart. Yield strength refers to the ability of a material to resist micro-plastic deformation. Beyond this limit, the material will not be able to return to its original shape, showing permanent deformation. But 5083 aluminum sheet is also relatively expensive.
Mechanical Properties
Temper | Tensile strength (MPa) | Yield strength (MPa) | Elongation (%) | Hardness (HB) |
5052 O | 195 | 90 | 25 | 46 |
5052 H32 | 230 | 195 | 12 | 60 |
5052 H34 | 260 | 215 | 10 | 68 |
5052 H112 | 215 | 132 | 22 | 52 |
Processability analysis
1) Corrosion resistance: 5052 aluminum has good corrosion resistance and is a typical anti-rust aluminum.
2) Weldability: 5052 aluminum alloy has good friction stir welding performance. Dynamic recrystallization occurs in the weld zone and The crystal of the weld seam is refined, and the weld seam can be bent freely at 0°C~180°C. Optimizing process parameters can make the strength of welded joints equal to or higher than that of the base metal.
3) Surface treatment: 5052 h34 aluminum can be anodized, the oxide film is easy to form, and the quality of the film is also better, which is more suitable for oxidation and coloring. When the magnesium content is high (such as 5083), its brightness is not enough. The magnesium content of 5052 is about half of that of 5083, which can be oxidized well, and the treated surface has high brightness and can be colored well.
