Aluminum 5083

Principal Design Features

This is a non-heat treatable alloy for strengthening. It has very good corrosion resistance, is easily welded and does have good strength.


Commonly used in the manufacture of unfired, welded pressure vessels, marine, auto aircraft cryogenics, drilling rigs, TV towers, transportation equipment, and in missile components.


No specific data. However the alloy is machinable by conventional means.


Forming characteristics are good for either hot or cold working.


Weldability of this alloy is very good by conventional means. When filler rod is required it should be the same alloy, 5083.

Heat Treatment

This is a non-heat treatable alloy.


Forging may be done in the range of 850 to 750 F.

Hot Working

Hot forming, when sever deformation is required, may be done at 400 F or higher to 700 F.

Cold Working

AL 5083 is readily cold worked by conventional methods. In the annealed (O temper) condition plate of 0.250 ” thick can be bent on 1.5 T radius.


Annealing may be done at 650 F for sufficient time for thorough heating, followed by air cooling.


Not applicable to this alloy.


Not applicable.


Hardening is accomplished by means of cold working only.
