  1. Duralumin By Group 2

  2. History of Duralumin • Duralumin was developed by the German • metallurgist Alfred Wilm at DürenerMetallwerke • AktienGesellschaft. In 1903, Wilm discovered that • after quenching, an aluminium alloy containing • 4% copper would slowly harden when left at room • temperature for several days. Further improvements • led to the introduction of duralumin in 1909. • The name is obsolete today, and mainly used in • popular science to describe the Al-Cu alloy system, • or 2000 series as designated by the International • Alloy Designation System (IADS) originally created • in 1970 by the Aluminum Association.

  3. Duralumin • It is strong and hard. • It is an alloy of aluminum that is 4 percentcopper, • 1 percent manganese, 0.5 percent, and 95.5 percent • aluminum • Ussually used for it’s lightness and strength.

  4. It is used for...... • making aircraft frames • making the frames of automobiles • and speedboats • making household articles

  5. Future Plans • * 2011: Wire, rod, and bar for screw machine products. • Applications where good machinability and good strength • are required. • * 2014: Heavy-duty forgings, plate, and extrusions • for aircraft fittings, wheels, and major structural • components, space booster tankage and structure, truck • frame and suspension components. Applications requiring • high strength and hardness including service at elevated • temperatures.

  6. * 2024: Aircraft structures, rivets, hardware, truck wheels, • screw machine products, and other miscellaneous structural • applications. The first age-hardened alloy ever discovered. • * 2036: Sheet for auto body panels. • * 2048: Sheet and plate in structural components for • aerospace application and military equipment. • * 2141: Plate in thicknesses of 40 to 150 mm • (1.5 to 6.0 in.) for aircraft structures. • * 2218: Forgings; aircraft and diesel engine pistons; • aircraft engine cylind
