Marine aluminum plate is the emerging market for R & D applications of aluminum products. Shipboard production capacity has also become an important indicator of the comprehensive strength of various aluminum processing enterprises. With the upgrading of domestic aluminum production process, leading enterprises in Henan Province - Mingtai aluminum plate production scale gradually expanded, increasingly rich types of alloys, product performance has reached the international advanced level.

At present, Compared with 5754 aluminum plate, 5086 aluminum plate, 5083 aluminum plate has been one the most promising aluminum alloys for shipbuilding industry, with excellent corrosion-resistance durable and Certified by DNV, CSS, ABS.

In the production of 5083 aluminum alloy, magnesium has a certain solid solution, is the main strengthening element. Its production processes are: ingredients—smelting—casting—homogenization—sawing—milling—heating—hot rolling—annealing—pre-stretching—sawing finished product size—acceptance. Hot rolling cracking is one of the common problems in marine grade aluminium plate 5083 alloy production before 2000. Since then, with the accumulation of experience, most enterprises have adopted the methods of controlling the content of trace sodium, improving the homogenization process, selecting the best rolling temperature and hot rolling process parameters, etc. to effectively improve the cracking of hot rolling. which reduces the production cost and increases the quality competitiveness.

Element requirements of 5083 marine aluminum plate:

Aluminum alloy 5083 is the typical marine grade aluminum, and aluminium plate 5083 usually used in shipbuilding industry, and the common temper are H116. The alloy content of aluminum alloy 5083 are: Al: reminder, Silicon Si: ≤0.40, Copper Cu : ≤ 0.10, Magnesium Mg: 4.0 to 4.9, Zinc Zn: ≤ 0.25, Manganese Mn: 0.40~1.0, Titanium Ti : ≤ 0.15, Chromium Cr: 0.05~0.25, Iron Fe: 0.000~ 0.400. The properties of 5083 aluminum plate are: Tensile strength σb (MPa): ≥ 270, Conditional yield strength σ0.2 (MPa): ≥110, elongation δ10 (%): ≥20, elongation δ5 (%): ≥12.

 

The performance requirements of marine aluminium plate 5083 are very strict. First, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, weldability, processability and surface quality are required. In order to ensure the quality and ensure sufficient toughness, the chemical composition of Mn/C is required to be above 2.5, and the carbon equivalent is also strictly required, and is produced by the manufacturer approved by the ship inspection department.
