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.

The Lightweight Durability of Aluminum Sheets

In the 1970's, there was a large-scale movement for beverage companies to stop using steel cans for soda pop and beer. Their existed the need to switch to an alternative material that offered lower cost in production, thus the aluminum can was born. Once word was out that aluminum weighed less, cost less and was recyclable, beverage companies were on board very quickly and the change became permanent. Today, aluminum, especially aluminum sheeting, is used for more industrial applications than ever before.

As a low-cost material that is both tough and lightweight, aluminum sheeting has been used across many industries for a number of years. In contrast to steel, aluminum weighs less than steel. Aluminum is cheaper to manufacture, and easier to bend into a variety of shapes. It can be shipped easily (less weight=less cost), and makes many items lighter in weight (cars, airplanes, etc.). Aluminum is also stronger and weighs less than tin, making aluminum a more cost feasible product.

The sheeting is available in a variety of grades. Each grade is manufactured with specific designated usages. Certain grades contain a combination of alloys to reinforce strength and/or chemical resistance; while other grades are heat-treated structurally, in order to maintain its resistance to corrosion. Commercially pure aluminum sheeting is generally regarded as the most chemically and weather resistant, but is not as strong as aluminum alloy grades.

Aluminum sheeting also comes in different thicknesses. In the manufacturing process, pre-treated aluminum ingots are passed through heavy rolls under massive amounts of pressure. The more pressure that is applied, the thinner and longer the aluminum becomes. Aluminum ingots can pass through many series of rollers to achieve their required gage, or thickness. Aluminum sheeting of any grade or alloy can extend from 0.006 inches to 0.080 inches thick. Any gage that is thinner than a gage of 0.006 is considered to be aluminum foil; whereas anything thicker than 0.080 is considered to be a metal plate.

Q:Why couldn't an aluminum kayak work?
The soft metal argument is silly. Use thicker aluminum or alloy for the bottom if you are concerned. Corrosion is even more ludicrous, I have a 60 year old aluminum boat. Aluminum does not corrode in salt water unless it is in contact with rusty iron for a long time. You do not have to weld, sealed rivets would work just as good. These are attempts to answer your question why can it not be done? Nobody can tell you because the truth is there is no reason there are no aluminum kayaks, so you aren t going to get a real reason why you shouldn t build one. The only good argument against an aluminum kayak is for use in white water, but we all know plastic is the only suitable material for that. An aluminum kayak would be amazingly light and much more scratch resistant than plastic or fiberglass.

Q:how do you get aluminium from rocks?
Aluminum is derived from a rock called Bauxite, which consists of a mixture of up to three aluminum minerals. Bascally they mine it, smelt it (heat to very high temperatures) and you get aluminum. You'll probably get a better answer form someone who is more familiar with the process, but that's a very rough idea.
Q:Confusing???? Anodising of Aluminium?
Anodising is a process in which the surface of a metal is modified. In the case of anodising aluminum the layer of aluminum oxide is made thicker. This is done by placing the aluminum in a sulfuric acid solution and passing a current through it so that it serves as an anode-the current releases oxygen at the surface of the aluminum increasing the aluminum oxide. I'm pretty sure this is from the reaction of the electric charge and the sulfuric acid producing oxygen as you showed in your last reaction with water. I hope this was helpful, I'm at work and don't have my old chem books and I dont' remember all this stuff off the top of my head.
Q:Copper and Aluminum Initial Temperature?
Quantity of heat given by aluminium = mc θ = 0.011* 913*(200 - 24) = 1767.6 J. . Quantity of heat given by copper = mc θ = 0.019* 385*(T - 24) = 7.315 T -175.56 J. . Mass of ethyl alcohol = volume * density = 0.000055 m^3 *789 = 0.043395 kg. Quantity of heat gained by ethyl = mc θ = 0.043395 * 2500*(24 - 15) = 976.3875 J heat lost.= Heat gained 1767.6 + 7.315 T -175.56 = 976.39 7.315 T = -615.65 T = -84.17 ˚C This shows that copper also gains heat. ======================================...
Q:hydrochloric acid + aluminum = ?
you may separate the hydrogen by electrolysis. purely take your tube of gas and place the tube face down in salt water. Then get yet another attempt tube and fill it halfway with salt water. The salt interior the water helps the water to grow to be a greater powerful conductor it is by the fact NaCl is an ion. This ionizes the water and helps conduction. Then after installation the attempt tubes, get a batter and connect it to a dazzling and unfavourable plate with the corresponding terminals on the battery. Then turn on the battery. The water ought to separate out of the tube, leaving the hydrogen. the different tube with be crammed with all the water. to answer your 2d question.... The gas that would want again out to be hydrogen. 6HCl + 2Al = 2AlCl3 + 3H2(gas)
Q:Would Aluminum foil sculptures sell?
It would have to be something they could not make by themselves. It would have to be durable. It would also help if the sculpture is useful in some way. Hey, I am just telling you what sells, from long experience. Maybe you would like to teach a class in foil sculpture instead. Try offering a class on Craigslist and see if anyone signs up. Or you could do videos or a pamphlet and sell those on Ebay. .
Q:how to bring back shine to aluminum window frames?
Your aluminium windows are possibly anodised which is a process carried out before the windows are assembled.Anodising is like a hard finished skin ,silver in your windows which was probably a semi sheen to begin with, some times this finish oxidises causing this white milky appearance. Anodising can be black,gold red, brown, and possibly other colours too used on motor cycles and sports equipment etc. Your neighbours window were probably anodised and polished (almost like chrome) again this would have been carried out before the windows were assembled. If this is the case no amount of cleaning will polish your anodising to a bright shiny finish. Contact an aluminium window installer/manufacturer as they have cleaning blocks, These look rather like a large pencil eraser containing metallic abrasive particles this may help. Your grey film is lightly to be the original siver turned dull. consult your aluminium window supplier to see if they can offer a better solution It may be possible to spray paint your window frames these would require acid etching and is a specialist procedure hope this is helpful good luck
Q:How does Aluminium and Oxygen bond?
Aluminum's outer shell is 3, not 13. 13 is the total number of electrons it has. Looking a the periodic table, Oxygen's usual valance state is -2 as an ion. Aluminum's valance state is always +3. This means that oxygen gains 2 electrons to get a charge of -2 and aluminum lose 3 electrons to get a charge of +3. As for electron configuration, aluminum has 13 electrons in total. 2 e- is in the 1st sublevel. 8 e- is in the 2nd sublevel. That leaves 3 e- left but 3 is not a stable number so aluminum wants to lose those 3 e- to become stable. Oxygen has 8 electrons. 2 e- is in 1st. 6 e- is in 2nd. 6 is not a stable number so oxygen wants to gain 2 more e- to become a full set of 8. Aluminum want to lose 3, Oxygen want to gain 2. We need to balance those. 3 x 2 = 6 2 x 3 = 6 Because Aluminum's usual state is +3, we can have 2 Aluminum atoms bonding. If both lose 3 e-, they both have stable outer shell of 8 (2nd sublevel) and lose 6 e- in total. Oxygen's usual state is -2, but there are 6 e- to gain to oxygen can have 3 atoms bonding. If all 3 atoms receive 2 e- in each, then that's 6 and they're all stable, also at 8 e-. So in order to turn them into happy atom, we need 2 Aluminum and 3 Oxygen to bond together. So the chemical formula is Al2O3 (Aluminum Oxide) *** I'm not very good at explaining, I did the best I can. As for the drawing, I can't do that on the computer. It would have been a whole lot easier if I can though.
