aluminum

تعريف aluminum في الإنجليزية الإنجليزية القاموس.: A metallic chemical element (symbol Al) with an atomic number of 13; Aluminum is one of the metal sidings It is more popular than steel because exposed areas of steel tend to rust Aluminum siding comes in long panels with baked-on enamel finish that can be smooth or textured Aluminum may dent and depending on how high or low the damaged panel is replacing it may be difficult Aluminum is a good heat insulator and is very waterproof Aluminum is composed of the same 3 basic parts as vinyl; A chemical element Rustproof, non-magnetic, silver-white lightweight metal, which is a good thermal and electrical conductor It is abundant in the earth's crust The atomic symbol is AL, atomic number is 13 and its atomic weight is 26 98; a silvery ductile metallic element found primarily in bauxite; In general terms, aluminum is a metal that is lighter than steel, but not as strong It can be machined (cut on a machine) to replace many plastic parts of an R/C car, but is not recommended for replacing suspension arms; Chemical symbol Al Silvery white metal; ductile with tensile strength and malleable; resistant to corrosion, but can be attacked by acids and alkalis; good conductor of electricity Lightweight, strong metal produced from alumina, which is processed from bauxite ore Commercial use is only 100 years old, yet the metal is second only to steel in tonnage consumed annually Used extensively in articles requiring lightness, corrosion resistance, or electrical conductivity Metal is used to make transportation, packaging, building, electrical, and consumer durable products; Aluminum can be found as a natural forming mineral or as a by product of water that is corrosive or aggressive Aluminum in the water may cause a discoloration or cloudy appearance The EPA maximum contaminant level for aluminum in water is 0 2 ppm; A lightweight, silver-colored, easily worked metal used in sculpture and architecture since about 1930 Â Aluminum is not an alloy The melting point of aluminum is 1200 degrees F; A conductive metal used in wafer fabrication to connect the various parts of the circuit; Eyeglass frame material that is lightweight, yet difficult to solder or weld, limiting its adaptability to different designs; While aluminum was once very popular, and is strong and light, it is not used quite as much, as it does not weld or solder easily and is somewhat difficult to adjust Aluminum does have a very unique look and feel to it; A lightweight, corrosion-resistant metal used for vertical and horizontal siding; A light, malleable metal that is a good conductor of electricity Commonly found in nature in oxidized form, bauxite; A silvery, lightweight, easily-worked metal that was used for dolls at the end of the nineteenth century until the early 1920s; just like titanium, aluminum is also a nonferrous metal Commonly used as handles, aluminum gives the knife a solid feel, without the extra weight The most common form of aluminum is T6-6061, a heat treatable grade The most common finishing process for aluminum is anodizing; A light ductile metal that is easy to weld It is a good conductor of heat and electricity When it is exposed to air, it creates a protective film resistant to corrosion It is used in alloys with copper, zinc, manganese and magnesium It is a very versatile metal and so has a wide variety of uses: packaging materials, utensils, auto-bodies, airplanes, building materials, electrical conductors, explosives, fireworks, abrasives, cosmetics, paints, and even food additives It is a natural component in soil, water, and air Inhalation of the fine powder can lead to pulmonary fibrosis; A non-rusting metal sometimes utilized in the fabrication of metal roofing, gutters and roof flashings; A silvery-white metallic element, the most abundant in the earth's crust, but found only in combination, chiefly in bauxite; A non-rusting metal used in roofing for metal roofing and the fabrication of gutter and flashings; A silver-white soft metal, noted for its lightness, high reflectivity, high thermal conductivity, nontoxicity, and corrosion resistance It is the most abundant metallic element, comprising about 1/12th of the earth's crust It is never found in nature as an elemental metal, but only in combination with oxygen and other elements In ordinary commercial and industrial use, the word aluminum is often understood to mean aluminum alloy, rather than the pure metal; A lightweight, silver-colored, easily worked metal used in sculpture and architecture since about 1930 Aluminum is not an alloy The melting point of aluminum is 1200 degrees F; Extruded aluminum is used in several SlideMaster units Aluminum rails can provide high stiffness while at the same time providing slide unit weights approximately 40% less than steel; and improved corrosion resistance; A chemical element, symbol Al, atomic number 13, and atomic weight 26 98 Important elemental material in conjunction with PQ products; Aside from copper, aluminum is the best heat conductor used for cookware It has even heat distribution and no "hot spots" where food will stick and burn; A master alloy element for many titanium alloys Aluminum is used to stabilize alpha microstructures Typical alloying weight percentages are from 2 to 7%; The metal most often used in semiconductor technology to form the interconnects between devices on a chip It can be applied by evaporation or by sputtering; Element No 13 of the periodic system; Atomic weight 26 97; silvery white metal of valence 3; melting point 1220 (degrees) F; boiling point approximately 4118 (degrees) F ; ductile and malleable; stable against normal atmospheric corrosion, but attacked by both acids and alkalis Aluminum is used extensively in articles requiring lightness, corrosion resistance, electrical conductivity, etc Its principal functions as an alloy in steel making; (1) Deoxidizes efficiently (2) Restricts grain growth (by forming dispersed oxides or nitrides) (3) Alloying element in nitriding steel; A lightweight, silvery white metal, it is so reactive chemically that it always occurs in compounds. It is the most abundant metallic element in Earth's crust, chiefly in bauxite (its principal ore), feldspars, micas, clay minerals, and laterite. It also occurs in gemstones, such as topaz, garnet, and chrysoberyl; emery, corundum, ruby, and sapphire are crystalline aluminum oxide. Aluminum was first isolated in 1825, became commercially available in the late 19th century, and is now the most widely used metal after iron. Its surface oxidizes at once to a hard, tough film, deterring further corrosion. Uses include building and construction, corrosion-resistant chemical equipment, auto and aircraft parts, power transmission lines, photoengraving plates, cookware and other consumer goods, and tubes for ointments and pastes. Important compounds include alums; alumina (aluminum oxide), useful as corundum and as a carrier for many catalysts; aluminum chloride, a widely used catalyst for organic syntheses; and aluminum hydroxide, used to waterproof fabrics; {i} malleable silvery metallic element used in alloys and in the manufacture of lightweight objects (Chemistry); see aluminium.
