Aluminum Alloy 5083 – Al 5083 H116 H111 H321
Aluminum 5083 is essentially a non-heat treatable alloy containing 4-4.9% Mg and 0.4-1.0% Mn. It is a relatively inexpensive alloy with moderate strength, excellent cold forming, welding and spot welding properties, and good corrosion resistance. 5083 aluminum alloy can be processed with moderate superplasticity. This attractive combination of properties has led to the increasing use of its superplastic forming for a variety of parts in non-structural applications that do not involve substantial forming deformations. Commonly used quenching conditions of the alloy include 5083-H116, H321, H111, H112, etc.
