As a core material for shipbuilding, the temper of 5083 aluminum plate—such as H321 and H112—directly impacts its mechanical properties, corrosion resistance, and suitable applications.

Marine-grade aluminum plates are resistant to seawater corrosion. These aluminum plates (such as 5052 and 5083) are essential in shipbuilding.

As a typical representative of the Al-Mg alloy series, the 5083-H321 Marine-grade Aluminum Plate has become a core material in modern shipbuilding due to its high strength, excellent marine corrosion resistance, and outstanding processability.

5083 marine aluminum plates are commonly used in the H116/H321/H112 temper states and are widely applied in the construction of ship hulls, warships, commercial ships, yachts, structural parts, bulkheads, decks, bridges, and protective facilities.

MC Aluminum produces 5083 marine-grade aluminum plates with a typical thickness range of 3–50mm, widths from 1000–3100mm, and lengths up to 1000–13000mm.
