Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.
Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."
Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: "This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina."[69] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, in a review of Davy's book, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound."
The -ium suffix conformed to the precedent set in other newly discovered elements of the time: potassium, sodium, magnesium, calcium, and strontium (all of which Davy isolated himself). Nevertheless, -um spellings for elements were not unknown at the time, as for example platinum, known to Europeans since the 16th century, molybdenum, discovered in 1778, and tantalum, discovered in 1802. The -um suffix is consistent with the universal spelling alumina for the oxide (as opposed to aluminia), as lanthana is the oxide of lanthanum, and magnesia, ceria, and thoria are the oxides of magnesium, cerium, and thorium respectively.
The aluminum spelling is used in the Webster's Dictionary of 1828. In his advertising handbill for his new electrolytic method of producing the metal in 1892, Charles Martin Hall used the -um spelling, despite his constant use of the -ium spelling in all the patents[58] he filed between 1886 and 1903. It has consequently been suggested[by whom?] that the spelling reflects an easier-to-pronounce word with one fewer syllable, or that the spelling on the flyer was a mistake.[citation needed] Hall's domination of production of the metal ensured that aluminum became the standard English spelling in North America.

- What is a moden? The answer to your second question is: Its about the materialsLet me give you an example: CD-ROM: Take a sheet of aluminum foilPlace it flat on a flat cutting board, then poke holes in various places with a forkThese holes are permanent and will not healThis is the way a CD/CD-Rom worksHoles are actually drilled through some metal with a powerful laser beamWhere the holes are become 0 and where the holes are not become 1READ-WRITE: Sprinkle a handful of rice on the cutting boardCover with a fresh piece of aluminum foilThen run your hand or a rolling pin over the foilYou will see 'bumps' in the foil Remove the foil, remove the rice and put the foil back down and run over it with the rolling pinThis tends to make the 'bumps' disappearPut rice down in a different pattern, smooth and you get a new set of bumpsThis is exactly the way a computer-burned CD-R or CD-RW worksA sheet of foil is sandwiched between layers of plasticA weak laser in your burner melts the plastic which creates a 'bump' in the foilCD drives read the bumps as 0 and non-bumps as 1Hope this helps.
- Q: firstly, what are the metal/alloy used in:cambell's soup cansmilo canspaint bucketsare they all tin?secondly:i have heard that we are not allowed to put metals in the microwave but i have done it with aluminium foil and it glows a little (like a bulb filament), however, that's only due to the electromagnetic currents and it doesn't spoil the microwaveshould be fine right? (assuming that the container is an open body and expanding gases are not an issue) i have heard about the metal reflecting the waves but it doesn't make senseelectromagnetic shielding occurs only with magnetic material (iron steel etc) so other nonmagnetic metals should be safe.please answer even if you only know answers to 1 questions :)
- Carbon nano tubes are stronger then steel, lighter then aluminum and more flexible then plasticWe're only a few years of from being able to mass produce it.
- Q: I am also interested in the worth of a pair as wellThey are 6 1/2 X 9 inches and are in an octagon shapeThey are heave for a small speakerThe back of it it metal, and looks like brass or browned tin or aluminumIt has the chrysler symbol on the magnet, and says quot;premium made in the usaquot; as well as numbersI can send pictures if requested, please help, im hoping to sell themI found them in my 1991 firebird formula in the sail pannelThank you fir the help!
- I don't think you have a fortune in your hands, they sound like speakers from the mid '70's, the heavy weight is magnet weight, supposedly the heavier the magnet, the better the soundI kept very few of the factory speakers I changed out for new Jensens, the originals had to be in very good condition, (cones not broken, wiring intact, etc.) before I'd keep themThe octagon shape was for fit in different model vehicles and the pentastar logo was on all Chrysler speakers.
