5083 Aluminium Specification
5083 - Alloyed with 4.45% magnesium, .65 % manganese and .15% chromium. Excellent weldability, light weight and good corrosion resistance
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.
Applications
Commonly used in the manufacture of unfired, welded pressure vessels, marine, auto aircraft cryogenics, drilling rigs, TV towers, transportation equipment and in missile components.
Machinability
No specific data. However the alloy is machinable by conventional means.
Forming
Forming characteristics are good for either hot or cold working.
Welding
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
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
Annealing may be done at 650°F for sufficient time for thorough heating, followed by air cooling.
Aging
Not applicable to this alloy.
Hardening
Hardening is accomplished by means of cold working only.
Other Physical Props
Electrical conductivity 28% of copper.
Other Mechanical Props
Shear strength in O temper is 25 ksi.
