Product Description:

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.

Q:Aluminum Magnet?
Nope. Aluminum is non-magnetic. If the pieces were sufficiently large, one could move them with a strong alternating field which would set off eddy currents. But that won't work on tiny shavings. Guess he will have to flush again and again and hope for the best.

Q:How do you clean an aluminum shower door?
any of the commerical over the counter products or try a mix of 50 prcent vinegar and 50 percent water
Q:Aluminum wiring safety?
Agree fully with trek even after certification a yearly torquing should be done of your bigger wires for the reason trek mentioned. Au is softer and expands more under heat. When it cools it contracts but the lugs or connectors don't contract as much and you start getting a lose connection which causes arching that causes more heat yadda yadda. As an electrician of 35+ years I can professionally say no aluminum is not what you want to see when buying a home. Not to mention they get brittle after time and exchanging a switch or plug has a high possibility of breaking or cracking the wire when doing so. Au wire was one of the blunders of the industry right up there with slab floor houses. Trying to cut cost in the industry to boost construction was less then stellar in the 60-70's and changes were made that haunt us tradesmen to this day. Good Luck
Q:What is the density of Aluminium Bronze?
aluminium is a metal... it has a valency of 3.. it has got all the props that a metal has for eg : lusturous, good conductor of heat and electricity..etc etc.... it is highly electropositive metal. it has emptyd orbitals and thus can borrow electrons and attain a stable confugeration... as its compounds are elctron deficient..! its compounds such as AlCl3 etc act as a lewis acid..the hybridisation state of Al is sp3d2... aluminium forms a thin protective oxide layer which prevents its further corrossion.. and this is also the reason y they do not react with weak acids.. Al is amphoteric(it reacts with acids as well as base) Al reacts with halogen to form trihalides... Al's covalency can be expected beyond 4 due to the presence of empty d orbitals...
Q:Skimless aluminum pouring wheel?
In continuous aluminum casting, a ring mold is fitted into the edge of a rotating casting wheel. Molten aluminum is then poured into the mold and cools as the mold assembly rotates without being skimmed. After the wheel has rotated about 160 degrees, the pliable aluminum bar is released.
Q:Whether aluminum foil can be used to heat the food?
Typically used as a wrap beverage packaging, food packaging bags of aluminum foil thickness of only 6.5 microns. This thin layer of aluminum can be waterproof, keep the flavor, anti-bacterial and anti-fouling. Aluminum foil trays holding food is very popular, although aluminum foil tray is disposable, but the ingredients are aluminum, less harmful to nature.
Q:When 0.073 mol of aluminum sulfate are dis- solved in enough water to make 253 milliliters of solution, what?
Aluminium sulfate is Al2(SO4)3 It dissociate in solution as follows Al2(SO4)3 -------------- 2Al3+(aq) + 3SO4(2-)(aq) You can see that 1 mole Al2(SO4)3 produces 2 moles Al3+ ions So 0.073 mol Al2(SO4)3 will produce (2 x 0.073) mol Al3+ ions = 0.146 moles So you have 0.146 mol of Al3+ in 253 ml Molarity = moles / L M = 0.146 mol / 0.253 L Molarity Al3+ ions = 0.58 M (2 sig figs)
Q:which material is better. Fiber or Aluminium?
I would choose fiber since I'm near the water.
Q:Do aluminum drum sticks (Ahead brand) damage rims and cymbals?
i have american hickory pro mark millennium and those work very good. they are 5A and i highly suggest them. my drum teacher thinks they are perfect. they make a good sound. i have asked about aluminum they dont damage anything but they dont sound as good and they look funny.
