6082 Marine Aluminum Tubing

In recent years, with the rapid development of the shipbuilding industry at home and abroad, reducing the weight of the hull,increasing the speed of the ship, and seeking aluminum alloy materials to replace steel components have become important issues for the aluminum processing industry and the shipbuilding industry.

Alloy 6082 has medium strength and good corrosion resistance, and is light in weight, which is an ideal material for manufacturing high-speed boat components. What are ,6082 aluminum properties?

Its tensile strength≥310MPa, yield point≥250MPa, elongation≥10%. Due to the high performance requirements of this product, Mg, Si, Fe and other elements mainly play a strengthening role, and a reasonable ratio is of great significance to the extrusion process and the performance of the final product. Therefore, it must be strictly controlled and the scope should not be too wide.

The 6082 alloy is characterized by containing Mn, which is a refractory metal, and the melting temperature should be controlled at 740-760 °C. Stir evenly for more than two times before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform.

The casting temperature of 6082 alloy is high (compared to the normal process of 6063), the casting speed is low, and the water flow is large. The above process needs to be strictly controlled and cannot be exceeded, otherwise it will easily lead to casting failure.

6082 aluminum has high deformation resistance, difficult extrusion, and high mechanical properties. After the homogenization treatment, the alloy microstructure changes as follows: (1) The intragranular segregation disappears; (2) The Ms2Si phase dissolves into α(Al), and the unbalanced eutectic disappears; (3) The β(Al9Fe2Si2) phase turns to α(Al12Fe3Si2 ) phase transformation and refine the iron-containing phase particles.

6082 marine aluminum tubing is heated by power frequency induction heating. The characteristics of this heating method are (1) the heating time is short, and the temperature can reach about 500 ℃within 3 minutes; (2) the temperature control is accurate, and the error does not exceed ±3 ℃.

According to the characteristics and performance requirements of 6082 alloy marine aluminum profiles, the above process is more reasonable. And Haomei 6082 aluminum profile has successfully passed the DNV certification. Welcome to leave message below to inquire it.

The Features of Marine Aluminum Sheet

The ship plate material was originally mainly steel. With the advancement of technology, aluminum alloy plates have been gradually used in yachts, ships and other hull parts. In recent years, many countries have successfully built all-aluminum ships. With the development of aluminum alloy technology, different parts like the hull, deck, piston and pump can be made of it.

The marine aluminum sheets have special requirements for strength, corrosion resistance, weldability, etc., so marine aluminum sheets are mostly made of aluminum-magnesium alloys, aluminum-magnesium-silicon alloys and aluminum-zinc-magnesium alloys, of which 5xxx aluminum is more often used, especially Al 5086, 5083 and 5754. What are their advantages?

1. Strong corrosion resistance. The ship needs to be immersed in water for a long time, especially seawater with high salinity and high corrosion. The aluminum alloy surface can produce a natural oxide film to resist external corrosion, and the anodized aluminum alloy can maintain a very stable state in seawater.

2. Excellent welding performance. Welding has more obvious advantages than riveting, because the performance lost due to welding cannot be recovered by re-heat treatment in shipbuilding, while industrial aluminum plates have good welding crack resistance.

3. Low density and lightness. The density of aluminum is only one-third of that of iron. Under the premise of the same hull size, the industrial aluminum hull brings lighter weight, which is greatly beneficial to the higher speed improvement of the ship and the fuel economy.

Marine yachts need to use 5083 aluminum plates, inland river ships can use 5456 aluminum plates and park boats generally use ASTM 5052 aluminum. These three alloys have relatively superior mechanical properties, corrosion resistance and welding properties, and are mainly used in the keel plate, curved outer plate and upper outer plate of the hull structure.

The Manufacturing Process of Aluminium 5083 H321

The 5083 aluminum alloy sheet has many advantages such as light weight, medium strength, and easy forming. It can be used in the manufacture of automobile parts, ships and truck tank. However, 5083 aluminum alloy has a relatively high Mg content. It is easy to precipitate β phase (Mg2Al3) at the grain boundary when placed at room temperature for a long time. The precipitation of β phase will make the material age soften.

In order to reduce the adverse effects of β phase precipitation, aluminum 5083 h321 was developed. Stabilizing annealing is carried out on the cold-deformed 5083 aluminum alloy sheet, so that part of Mg can be uniformly precipitated in the alloy in the form of β phase, ensuring that the material after aging softening still meets the performance requirements.

In the manufacturing process of 5083 h321 sheet, the amount of cold deformation after recrystallization annealing, and the temperature and time of stabilization annealing after cold deformation are three key process parameters that affect the final properties of the 5083 aluminum plate.

During the cold deformation process, as the amount of cold deformation increases, the plate lattice distortion and the degree of grain breakage will increase, and the large grains will be elongated along the rolling direction to form a fiber or band-like structure, and a large number of bits will be generated inside the grains. The interaction between dislocations is enhanced, therefore, the strength of the alloy increases.

With the increase of the annealing temperature and the extension of the holding time of the stabilized annealing, the tensile strength and the yield strength will decrease. This is due to the large deformation storage energy accumulated after the cold working of the plate, which causes recovery and softening during annealing. Partial work hardening is eliminated, so the strength is reduced and the elongation is increased.

As the amount of deformation increases, the intergranular corrosion resistance of 5083-H321 sheet decreases, and when the amount of deformation and the stabilization annealing time are the same, the intergranular corrosion resistance of the plate depends on the temperature of the stabilization annealing.A cold deformation of 20% and a stabilized annealing system of 180℃/2h are the best production processes for the 3 mm 5083 aluminum sheet.
