In terms of prevalence in the earth's crust, it takes 3rd place after oxygen and silicon among all atoms and 1st place among metals. From the history of the appearance of aluminum For the first time aluminum was obtained by Hans Oersted in 1825. The modern method of aluminum production was developed independently by the American Charles Hall and the Frenchman Paul Héroux. Since its discovery in the middle of the 19th century, it has been considered one of the most valuable for its amazing qualities: white as silver, light in weight and not affected by the environment. Its value was higher than the price of gold. Not surprisingly, aluminum is primarily used in jewelry and expensive decorative items. In 1855, at the Universal Exhibition in Paris, aluminum was the most important attraction. Aluminum productswere located in a display case adjacent to the diamonds of the French crown. Gradually, a certain fashion for aluminum was born. It was considered a noble, little-studied metal used exclusively for the creation of works of art. Aluminum is the metal of the future Today aluminum is one of the most popular and widely used metals. The advantages of aluminum and its alloys include its low density, relatively high strength characteristics, good thermal and electrical conductivity, manufacturability, and high corrosion resistance. The combination of these properties makes it possible to classify aluminum as one of the most important technical materials. Aluminum is widely used in various types of transport. At the current stage of aviation development, aluminum alloys are the main structural materials in aircraft and shipbuilding. Aluminum is widely used as a structural material. The main advantages of aluminum in this quality are lightness, pliability to stamping, corrosion resistance (in air, aluminum is instantly covered with a strong film of Al 2 O 3 , which prevents its further oxidation), high thermal conductivity, and environmental friendliness of its compounds. Aluminum and aluminum alloys are non-toxic, easy to sterilize and clean, and meet all hygiene requirements. In particular, these properties have made aluminum extremely popular in kitchenware, aluminum foil in the food industry, and for packaging. Сплавы на основе алюминия, благодаря уникальному комплексу свойств, успешно выдерживают конкуренцию со стороны других конструкционных материалов, таких как сталь, чугун, медные сплавы, бетон и др. Важнейшее из этих свойств - способность к рециклингу. Полученный однажды из руды алюминий может быть многократно, с применением соответствующих технологий, переплавлен и снова использован для изготовления изделий. При этом экономится 93% энергии, требующейся для получения первичного металла. Переработанный алюминий все более активно заменяет в изделиях первичный алюминий и в развитых странах его доля в общем потреблении алюминия уже превышает 30%. Но такая замена становится возможной только потому, что качество этого алюминия не уступает первичному металлу, полученному из руды. По существу, все чаще термины "первичный" или "вторичный" относится к источнику сырья, а не к уровню качественных характеристик сплава. Это результат технологического прорыва в процессах и оборудовании для подготовки сырья, плавления, обработки расплава и разлива, произошедшие на последние 10 лет. The melting point for industrial aluminum is 658 °, for high-purity aluminum is 660 °, the specific heat of fusion is 390 kJ / kg, and the boiling point is 2500 °. The density is 2.7 g / cm³. The electrical conductivity is 65% of the electrical conductivity of copper. Aluminum is highly reflective. A special place in the use of aluminum is occupied by its alloys, behind which lies the future of science and technology. Cars, computers, airplanes, devices in 2020 will be made of aluminum - the metal of the 21st century. In the next hundred years, the need for "winged metal" will increase more than ever: - More and more energy will be needed for the needs of construction - already now 50% of the world's population, according to the UN, live in megacities. - Communications will become global: computer networks will entangle the whole world, and they will need more and more aluminum. - The development of space technologies will require even more metal production. home Products Gallery Delivery Contacts LLC "TD Remetall-S" © 2010 design and development by Unico Design
