Heat treatment:
Alloy 5083 can be heat treated to increase its strength. The most common heat treatment conditions are:
O-Condition (Soft): No heat treatment, the material is in the as-supplied condition.
H111 Temper: Uniformly rolled and stress relieved to reduce strength.
H321 Temper: Uniformly rolled and stress relieved to reduce strength and improve resistance to stress corrosion cracking.
H116 temper: Strength properties improved by heating and subsequent solution heat treatment.
Applications:
Alloy 5083 is used in various applications that require high corrosion resistance and strength such as:
Shipbuilding: boat hulls, deck structures, bulkheads
Offshore structures: oil platforms, maritime constructions
Vehicle construction: fuel tanks, truck bodies, trailers
Aerospace: aircraft parts, aircraft construction
Defense industry: military vehicles, tanks
Industrial applications: pressure vessels, heat exchangers, pipelines
