Aluminum Metal
642 wordsAluminum is the most abundant metal and the third most abundant element in the earth's crust, after oxygen and silicon. It accounts for about 8% of the earth's total mass (Tar buck 103). Aluminum is a transition metal and is very chemically reactive; too reactive to occur naturally as a free metal. Instead it can be found in over 270 different minerals. The chief ore of aluminum is bauxite which is a mixture of hydrated aluminum oxide (Al 2 O 3+xH 2 O) and hydrated iron oxide (Fe 2 O 3+xH 2 O) (...

1,285 wordsCorrosion and rubbing alcohol vs. corrosion and hydrogen peroxide " Are brass, lead, iron, and aluminum more likely to corrode in solutions of rubbing alcohol or hydrogen peroxide?" a. Definition-corrosion, rust, oxidation Corrosion is the atmospheric oxidation of metals. Rusting is essentially a process of oxidation in which iron combines with water and oxygen to form rust. Rust is the reddish-brown crust that forms on the surface of iron. Rust, a chemical compound, is a hydrated ferric oxide F...

Most Useful Features Of Aluminum
2,139 wordsAluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure al...

Oxide Of Aluminum
963 wordsAluminum, symbol Al, the most abundant metallic element in the earth's crust. The atomic number of aluminum is 13; the element is in group 13 ( a) of the periodic table. Hans Christian Or stead, Danish chemist, first isolated aluminum in 1825, using a chemical process involving potassium amalgam. Between 1827 and 1845, Friedrich W"o hler, a German chemist, improved Oersted's process by using metallic potassium. He was the first to measure the specific gravity of aluminum and show its lightness. ...

Aluminum Into Useful Products
2,198 wordsAluminum Aluminum is a lightweight, silver-colored metal that can be formed into almost any shape. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into wire or made into cans. Aluminum does not rust, and it resists wear from weather and chemicals. Aluminum is called aluminium in English-speaking countries outside the United States. Its atomic number is 13 and its atomic weight is 26.9815. Pure aluminum, known as Al on the periodic ...

Aluminum Oxide Al 2 O 3
545 wordsCorundum: A compound of elements Corundum is a mineral consisting of aluminum oxide with a chemical formula Al 2 O 3. Aluminum is the most abundant metallic material in the crust of the earth; only the oxygen and silicon are found in greater abundance. Aluminum is never found as a free metal. It is commonly found as aluminum silicate or as a silicate of aluminum mixed with other metals such as sodium, potassium, iron, calcium, and magnesium. These silicates are not useful ores and it is chemical...

Begins With An Aluminum Body Structure
1,251 wordsAluminum usage in automobiles and light trucks has been climbing steadily. Even more important, auto manufacturers are beginning to see aluminum the way aircraft manufacturers do - as the basic structural material for their vehicles. Increasingly, in the case of carmakers, that thinking begins with an aluminum body structure such as the spaceframe. It's a new and potentially powerful trend. As recently as 1990, there were no aluminum-structured passenger cars in production anywhere in the world....
