5083 aluminium alloy is an aluminium alloy with magnesium and traces of manganese and chromium. It is highly resistant to attack by seawater and industrial chemicals.[1]

Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys with a Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65°C.[2]


For AA 5083 alloy, the stages of porous structure development are substantially identical with that of pure aluminium, although an increase in oxide growth rate and high conductance of the oxide film were observed.

Chemical composition[edit]

The composition of 5083 aluminium is:[3]


Alloy 5083 is commonly used in:

Uses requiring a weldable moderate-strength alloy having good corrosion resistance are commonly utilizing alloy 5083.
