Marine Heavy Duty Aluminum Plates Sheets generally refer to thick aluminum alloy plates and heavy gauge sheets produced from marine-grade alloys such as 5083, 5086, 5059, and 5383.
Aluminum / Steel Clad Plates consist of a sandwich construction in which a layer of marine-grade aluminum alloy is metallurgically bonded to a steel substrate.
Marine 5083 Aluminum Plate belongs to the 5xxx series of aluminum-magnesium alloys and is classified as a non-heat-treatable alloy. Its high magnesium content (typically 4.0–4.9%) enhances its corrosion resistance, especially against seawater-related degradation such as pitting and stress corrosion cracking.
Marine 5052 Aluminum Plate is noted for its exceptional resistance to corrosion caused by seawater, salt spray, and marine atmospheres.
5086 Aluminum Plate belongs to the 5xxx series of aluminum-magnesium alloys. Its hallmark is a high magnesium content—generally between 4.0% and 4.9%—which delivers enhanced corrosion resistance, particularly against saltwater and marine atmospheric conditions.
Marine 5059 Aluminum Plate is distinguished by its high magnesium content and carefully balanced alloying elements, designed to maximize strength without compromising corrosion resistance.
The 5383 aluminum alloy belongs to the 5xxx series of aluminum-magnesium alloys known for remarkable resistance to marine corrosion and high strength.
