Duralumin has the following uses:

It is used for making wire, bar and rods for the screw machine products. It is used in places where good strength and good machinability are required.It is used in heavy-duty forgings, wheels, plates, extrusions, aircraft fittings, space booster tankage and trauck frame, and other suspension components. It finds applications in places where high strength is required, and services at elevated temperatures.It is used for making Aircraft structure, truck wheels, screw machine products, rivets and other structural application products.It is used as a sheet for the auto body panels.It is also used in forgings, in aircraft engine pistons, impellers of the jet enginesand the compressor rings.It is also used for making die and hand forgings.

There is a proper method that is used for the conversion of Duralumin into ingots. It has to undergo a high pressure before being converted to ingots. This pressure treatment includes rolling, pressing and so on. It is then converted to plates, sections, sheets, tubes and wires. It is quenched in water at a temperature of about 500 degree Celsius, for about four days. This is called natural aging. Often, it undergoes artificial aging at a temperature of about 190 degree Celsius, This heat treatment ultimately leads to the inculcation of various strengths in duralumin. In fact, the initial period in which metal airplane was constructed with duralumin; it had to go through these processes. Duralumin is also used widely in the surface transportation, aviation and mechanical engineering.
