It also provides information on non-tariff measures affecting aluminium and aluminium products. Section V describes the activities in other international organizations related to aluminium. SECTION I: Main Features of the Aluminium Industry Properties of aluminum¹ 3. Aluminium is the third most abundant element in the earth's crust after oxygen and silicon. The metal has been in commercial production for almost 100 years. Aluminium weighs about one-third as much as copper ¹Physical properties of aluminium: Symbol: Al (Aluminium) Density at 200C (68°F): 2.699 Atomic number: 13 Atomic weight: 26.98154 Melting point: 660.2°C Boiling point: 2,477 - 50°C Electrical conductivity: m ohm-¹ cm-¹: 0.382 ²Though aluminium is the most common non-ferrous metal in the earth's crust, it was isolated only in 1825, by Hans Christian Oersted. In 1809, Sir Humphrey Davy proved that clay (aluminium silicate) had a metallic base. Davy suggested the name aluminum for this metal, a name which has been retained in North America but modified to aluminium in most other countries. Hans Christian Oersted was the first to produce the metal (in 1825). In 1827, Friedrich Woehler described the production of aluminium as a powder and in 1845, he was able to make slightly larger amounts of the metal and determine some of its physical properties. Aluminium was introduced to the public in 1855 at the World Exhibition in Paris as a primary metal produced on a laboratory scale. It was not until 1886, after the modern electrolytic method of producing aluminium was discovered almost simultaneously by Charles Martin Hall in the United States and Paul L.T. Heroult in France, that it became a metal of industrial importance. MDF/W/61 Page 7 and steel, is malleable, ductile and easily machined and cast. It has excellent corrosion resistance, high thermal and electrical conductivity and a silvery appearance. It is a versatile metal with many uses, and is only exceeded by iron in terns of the volume of world consumption. Aluminium can be alloyed with many other materials, which, after treatment, have strengths approaching that of mild steel. 4. On account of its high chemical re-activity, aluminium, unlike many other metals, does not occur in the metallic form in nature, but is a common constituent of many minerals, where it is normally present in combination with silicon, oxygen, hydroxyl groups, iron, titanium, calcium and to a lesser extent, with fluorine, phosphorus and boron. The bauxite res, containing the minerals gibbsite, boehmite and/or diaspore, which are currently the main sources of aluminium, account for only a small part of the aluminium present in the world. Other potential sources of aluminium are igneous rocks, sedimentary rocks and metamorphic and metasomatized wocks . World bauxite reserves 5. The principal ore of aluminium is a mixture of hydrous aluminium oxides called bauxite which may occur as a massive hard rock, loose pisclites, or soft clay. Karstic (associated with limestones) and lateritic (usually with aluminosilicate rocks) bauxites are found in most :ountries, with the major resources located in tropical regions. in 2 1985, world bauxite reserves were estimated at about 21 billion tons (Table l), almost 72 per cent of these reserves are in developing countries. About 52 per cent are located in the following four developing countries: Guinea (26.7 per cent), Brazil (10.7 per cent), Jamaica (9.5 per cent), and India (4.8 per cent). Developed countries account for about one-fourth of bauxite reserves. Australia has the world's second target reserves of bauxite, with over 21 per-cent of total world reserves. Processing Bauxite processing 6. About 90 per cent of all bauxite supplies are mined by open-pit methods.

The method for producing Al12Mg17 intermetallic powder is presented. The dispersity, morphology, chemical composition, and phase composition of the obtained powder materials were investigated. Certain thermodynamic properties of high-energy materials containing the Al-Mg powder after mechanical activation of various durations were investigated. The addition of the Al-Mg powders to the high-energy composition (synthetic rubber SKDM-80 + ammonium perchlorate AP + boron B) can significantly increase the burning rate by approximately 47% and the combustion heat by approximately 23% compared with the high-energy compositions without the Al-Mg powder. The addition of the Al12Mg17 powder obtained after 6 h of mechanical activation provides an increase in the burning rate by 8% (2.5 0.1 mm/s for the mechanically activated Al Mg powder and ± 12 17 2.3 0.1 mm/s for the commercially available powder) and an increase in the combustion heat by 3% ± (7.4 0.2 MJ/kg for the mechanically activated Al-Mg powder and 7.1 0.2 MJ/kg for the commercially ± ± available powder).

  • Aluminium Alloys Chemical Composition Pdf
    Aluminium alloys chemical composition pdf Continue Alloy in which aluminum is the predominant lye frame of aluminum welded aluminium alloy, manufactured in 1990. Aluminum alloys (or aluminium alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. Typical alloy elements are copper, magnesium, manganese, silicon, tin and zinc. There are two main classifications, namely casting alloys and forged alloys, both further subdivided into heat-treatable and heat-free categories. Approximately 85% of aluminium is used for forged products, e.g. laminated plates, foils and extrusions. Aluminum cast alloys produce cost-effective products due to their low melting point, although they generally have lower tensile strength than forged alloys. The most important cast aluminium alloy system is Al–Si, where high silicon levels (4.0–13%) contributes to giving good casting features. Aluminum alloys are widely used in engineering structures and components where a low weight or corrosion resistance is required. [1] Alloys composed mostly of aluminium have been very important in aerospace production since the introduction of metal leather aircraft. Aluminum-magnesium alloys are both lighter than other aluminium alloys and much less flammable than other alloys containing a very high percentage of magnesium. [2] Aluminum alloy surfaces will develop a white layer, protective of aluminum oxide, if not protected by proper anodization and/or dyeing procedures. In a wet environment, galvanic corrosion can occur when an aluminum alloy is placed in electrical contact with other metals with a more positive corrosion potential than aluminum, and an electrolyte is present that allows the exchange of ions.

The driving force behind this effort is the reduction of costs, by extending the service life of aircraft parts (structural and engine components) and increasing fuel efficiency, load capacity and flight range. The present paper examines the most important classes of metallic materials including Al alloys, Ti alloys, Mg alloys, steels, Ni superalloys and metal matrix composites (MMC), with the scope to provide an overview of recent advancements and to highlight current problems and perspectives related to metals for aeronautics. Keywords: alloys; aeronautic applications; mechanical properties; corrosion resistance 1. Introduction The strong competition in the industrial aeronautic sector pushes towards the production of aircrafts with reduced operating costs, namely, extended service life, better fuel efficiency, increased payload and flight range. From this perspective, the development of new materials and/or materials with improved characteristics is one of the key factors; the principal targets are weight reduction and service life extension of aircraft components and structures [1].

W ork of the Technical Committee : Committee for Aluminium Conductors. H. Schmitt (chairman) (Z. Metalllcunde, 1934, 25, 170-172).— The behaviour of the following types of free transmission conductors on the Island of Sylt during 5 yrs.’ exposure is described: (A) 99-2% aluminium after slowly cooling from 350° C., (B) 99-6% aluminium, (C) 99-2% aluminium quenched from 500° C., Aldrey, and copper. The conductors consisted of several strands of wire twisted into a rope. The breaking load of Aldrey decreased from 180 to 160 kg., that of alum inium B and C from about 85 to 78 kg., and that of aluminium A from 80 to 60 kg. in 5 yrs. The decrease was linear throughout the period for Aldrey and aluminium A, but for aluminium B and C the decrease occurred only during the first 2-3 yrs., after which the strength remained constant. For copper the strength remained constant for the first 3 yrs., then commenced to decrease linearly with time of exposure. The surface of aluminium B and C became covered with a protective film which appeared to act as a preventive against further corrosion; the films formed on the other metals were porous and poorly adherent, and therefore afforded little protection.— A.
