The main processing technology of 5052 marine aluminum sheet is currently through hot rolling production line, which is mainly used in yacht hull and hull parts. 5052 marine alloy aluminum sheet has a higher magnesium content than other alloys, so it has a good anti-rust function, which is also an important reason for 5052 marine aluminum sheet to be used in hulls. Magnesium has high strength, anti-rust function and corrosion resistance, which can well cope with the corrosion of seawater and fresh water.
What is 5052 Aluminum?
5052 aluminum sheet is an aluminum-magnesium alloy aluminum sheet, which is a widely used rust-proof and corrosion-resistant aluminum material. 5052 aluminum sheet has medium strength and has relatively good fatigue strength: plasticity and corrosion resistance.
5052 aluminum is the strongest alloy among the non-heat-treatable grades. Its fatigue resistance is superior to most grades of aluminum. Alloy 5052 has good resistance to saltwater corrosion in marine atmospheres and excellent machinability
5052, 5083, and 5086. All three of these aluminums are produced primarily as rolled material (in sheets or sheets) commonly found in ship hulls. With high tensile strength and excellent corrosion resistance at weld points, these alloys are well suited for use in marine applications
