Duralumin definition, an alloy of aluminum that is 4 percent copper and contains small amounts of magnesium, manganese, iron, and silicon: used for applications requiring lightness and strength, as in airplane construction. Indeed, nations that were facing severe shortages of raw materials such as Britain or Germany used wood for aircraft construction. Duralumin is an alloy of aluminium (94%), copper (4%) and magnesium (1%). It is used in heavy-duty forgings, wheels, plates, extrusions, aircraft fittings, space booster tankage and trauck frame, and other suspension components. The following are some of the major applications of duralumin: 1. Because of its lightness and other desirable physical properties, duralumin is widely used in the aircraft industry. Aluminium can also be used to make smart alloys. Because aluminum loses corrosion resistance when alloyed, a special laminated sheet form called alclad is used for aircraft construction; it has thin surface layers of pure aluminum covering the strong duralumin core. Thus the alloy is especially suited to the construction of aircraft (huge airships such as the German craft designed by Ferdinand, Graf von Zeppelin (1838–1917), would not have been possible without duralumin) and internal-combustion engines. Because of its lightness and other desirable physical properties, duralumin is widely used in the aircraft industry. Next choice is Duralumin, an alloy of aluminum, which is light as well as durable. Surgical and orthopedic work 5. One of the first passenger aircraft, the Junkers F 13 (1919), was a full -metal aircraft was used in the Duralumin as the material for the chassis. La pieza de trasvase P 1 (figura 1) se fabrica en duraluminio o latón.

Their light weight and consequent high strength per unit weight compared with steel suit them for aircraft construction. Duralumin is the main material for aircraft manufacturing and the space industry. n. An alloy of aluminum that contains copper, manganese, magnesium, iron, and silicon and is resistant to corrosion by acids and seawater. Most sheet aluminum used in aircraft is an "al-clad" alloy - the majority of the sheet is an alloy, but it is clad with a thin layer of pure aluminium to prevent corrosion. Duralumin is the main material for aircraft manufacturing and the space industry. The first application for aircraft occurred in 1911 during the construction of airships. Aluminium can also be used to make smart alloys. On the other hand, aluminum alloy 2024 in sheet forms , are used in commercial and military aircraft for fuselage skins. Aluminum is the most vital metal in aircraft production. ‘He said the shoes were made from the super lightweight alloy metal widely used in aircraft - Duralumin - which had the strength of steel and the lightness of aluminium.’ More example sentences ‘Many of the earliest metal propellers were manufactured in one piece of forged Duralumin.’ By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. The main alloying constituents are copper, manganese and magnesium. With this new rip-resistant mixture, duralumin quickly spread throughout the aircraft industry in the early 1930s, where it was well suited to the new monocoque construction techniques that were being introduced at the same time. Before a final heat treatment the alloy is ductile and malleable; after heat treatment a reaction between the aluminum and magnesium produces increased hardness and tensile strength. Sciences, Culinary Arts and Personal 6 years ago. It is used in places where good strength and good machinability are required. While every effort has been made to follow citation style rules, there may be some discrepancies. Advantage is taken of the rigidity of corrugated duralumin sheets to use them as wing covering in a way to form part of the structure and prevent torsion. A commonly used modern equivalent of this alloy type is AA2024, which contains (in wt.%) 4.4% copper, 1.5% magnesium and 0.6% manganese. 57 Although in 1939, Duralumin was the material of modern aviation, wooden aircraft were still used during the Second World War. - Definition, Process & Examples, NY Regents Exam - Chemistry: Help and Review, NY Regents Exam - Living Environment: Help and Review, High School Physics: Homework Help Resource, AP Environmental Science: Homeschool Curriculum, Holt McDougal Modern Biology: Online Textbook Help, Physical Geology Syllabus Resource & Lesson Plans, Middle School Earth Science Curriculum Resource & Lesson Plans, ScienceFusion The Dynamic Earth: Online Textbook Help, ScienceFusion Earth's Water & Atmosphere: Online Textbook Help, ScienceFusion Space Science: Online Textbook Help, ScienceFusion Ecology and the Environment: Online Textbook Help, Biological and Biomedical All rights reserved. It has a higher strength to weight ratio than pure aluminium. Duralumin also is popular for use in precision tools such as levels because of its light weight and strength. 2 Answers.
