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:Why does aluminum react this way?
Aluminum reacts like the elements in its group, the elements that are above and below it, such as Boron and Gallium. This is due to its valance electrons which you can find out through its electron configuration. It has 3 valance electrons, while the other elements you mentioned follow different rules due to their valance electrons. Ultimately, aluminum does not act like those because it is not in that family/group.
Q:Can you FORGE aluminum in a REGULAR WOOD BURNING FIRE?
Yes, but you would need an ample air source to feed the combustion process of the forge. Aluminum melts at about 1200-1400 hundred degrees Farenheit, most pot metals will melt at around 750 -900 degrees. In the olden days you saw blacksmiths pumping a Bellows to provide the combustion air because they needed to get the metal Red hot so as to work and stretch the metal. Aluminum with its high melting point required constant heating and air being applied to get it to that required heat for working the metal. In your case an air compressor supplying a high level of air mixed with oxygen would be the only way you could do this unless you had a high temperature metal forge unit. The air bellows pump is built into the forge.
Q:Can microwave oven use aluminum foil?
Yes, it does matter.Microwave produced by microwave oven belongs to radio frequency band, usually around 2500MHz. This band of microwaves has the following features: 1) it can be absorbed by food and water, causing molecules to move violently and produce heat. 2) not absorbed by plastics, ceramics, or glass. 3) the metal conducts electricity under the influence of the electric field of the microwave. The electric field of thick metal can resist the microwave, and the microwave reflected out, so the inner wall of the microwave oven is made of thick metal; if the thick walled metal container in the microwave and metal containers will reflect the microwave so that the food is not heated. But the foil is too thin, so electrical conductivity can cause a catastrophic reaction. The process of conducting a thin metal so rapidly that its temperature rises linearly can cause a fire. At the same time, the tip produced by the heat contraction of the foil causes sparks, which can ignite any combustible material in the microwave oven.
Q:What's the maximum temperature that high temperature resistant aluminum tape resists?
Aluminum tape is made by calendering aluminum and thus an oxide of aluminum. The melting point of aluminum is 660.4℃ and its boiling point 2467℃. Aluminum foil can resist high temperature, but it can be oxidated. Aluminum oxide is an white power and belongs to covalent compound with the melting point of 2050℃ and boiling point of 3000℃.
Q:Will a aluminum heatsink work with an AMD Phenom?
Hi Yes ,if it is an AM2 heat-sink.
Q:Why does volatile test need aluminum package?
Q:Aluminum oxide is formed from the reaction of metallic aluminum with oxygen gas. How many moles of Aluminum ar
#1 The balanced equation will be: 4 Al + 3 O2 -- 2 Al2O3 Since the ratio of aluminum to aluminum oxide is 2:1, just multiply the moles of Al2O3 by 2 to get the moles of Al needed. #2 The reaction is between H2 and N2 to give NH3. H2 + N2 -- NH3 To balance it, since you have N2 on the left, you'll form 2 NH3 on the right. That gives you 6 H on the right, so you'll need 3 H2 on the left. The balanced equation is: 3 H2 + N2 -- 2 NH3 So get to the answer, first convert the grams of H2 into moles by dividing the the molar mass of H2. Then, use the coefficients of the equation to convert moles of H2 into moles of NH3. Finally, use the molar mass of NH3 to convert moles of NH3 into grams of NH3.
Q:How does aluminum foil help radio waves in real life?
You are not able to use just any foil. You need specified alien security foil. It is rather targeted and difficult to manufacture, so it is rather steeply-priced. Most effective secret govt agencies can get it, but i have smuggled a supply out of the federal government place of work the place I work and am inclined to sell it to you for only $100 a rectangular foot. Contact me off record.
Q:where is the cheapest place to buy aircraft aluminum?
If your thinking of useing it to buy and resell for scrap , you cant make beer cans out of this kind of aluminum as it would be very dangerous and poisonous. The bone yard in victorville ali and all aver arizona has them but you really cant sell them or buy them
Q:Carbon or Aluminum cranks...?
There are some very good carbon cranks out there, and there is also a lot of junk. If you have Shimano components on your road bike, their aluminum cranksets are hard to beat, light and stiff and reliable. Carbon cranks will be more expensive, and perhaps a bit lighter, but may not work as well with your components. I recently upgraded my bike with Campagnolo ultra torque carbon cranks. They are lighter and stiffer than my old square taper aluminum cranks because they are a completely different design, not because they are carbon
