Aluminium alloy 5083 contains 5.2% magnesium, 0.1% manganese and 0.1% chromium. In the tempered condition, it is strong, and retains good formability due to excellent ductility.
This is an excellent marine environment corrosion resistant aluminum alloy, It is primarily an alloy used for its corrosion resistant properties as it is especially good on inter granular corrosion resistance. Also, the tensile and yield strength is higher than 5086 alloy, so often these properties too are used by designers for their aluminum vessels. This alloy also has good welding capabilities for fabricating vessels.
Physical properties of 5083 aluminum sheet
The 5000 series grades of aluminium are non heat-treatable alloys. 5083 alloy aluminium metal sheet has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures in excess of 65°C.
Aluminium 5083 has higher Tensile and Yield strengths than Alloy 5086 but less than 5456. it is a strong magnesium-manganese-chromium-aluminium alloy. It can be hardened by cold work.
5083 aluminum sheet is a medium strength, composed mainly of aluminum, magnesium and manganese and standard specifications include AMS 4057, AMS 4058, ASTM B210 and more.

Alloy 5083 aluminum plates have higher strength than 5052 plate and has exceptional thermal conductivity. In the tempered condition, it retains good formability due to excellent ductility, and it is easy to form, stamp and weld.
It is highly suitable for welding and can be hardened by cold work. Because Alloy 5083 with excellent corrosion resistance, particularly salt water corrosion resistance, it is used in marine applications.
Since Alloy 5083 aluminum sheet plate is capable of withstanding extremely low temperatures without brittleness or loss of properties, it is especially suited to the cryogenic market. Alloy 5083 has been used in vehicle armor plate due to its high strength factor.
Aluminium 5083 is known for exceptional performance in extreme environments. Aluminium 5083 is highly resistant to attack by both seawater and industrial chemical environments. The temper is achieved by the plate being fully annealed and then rolled to the required temper, rather than being heat treated.
