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:What is the lightest aluminum wheel set?
topolino makes some killer sets. the carbon core cx2.0 weight 1340 grams. i have a set and love it, stiff, light and fast. very durable. bikingthings
Q:Abrasive that wont scratch aluminum?
A hammer and liquid nitrogen
Q:The chemical composition of aluminum foil
A metal foil: Aluminium directly rolled into sheets of hot stamping material, the effect of stamping and silver foil stamping similar effects, it is also called the false silver foil.Main chemical composition: Aluminum (Al)
Q:The foil and foil is the same?
Aluminum foil and foil have foil or aluminum foil used for wrapping food barbecue, to prevent burnt meat. Aluminum foil and foil is very easy to distinguish, silver foil appears bright than many, but the ductility of tin is very poor, a pull off. Supermarket sales of pure tin foil, which is usually a stacked, with each tissue, itself is difficult to cut, the price is also more expensive, fewer buyers. The aluminum foil material stiffness, good cutting, using reel packaging, the price is cheaper, it has gradually become the mainstream of the market
Q:Aluminium properties????? 10points?
1) Aluminium is very light weight 2) Aluminium naturally generates a protective oxide coating and is highly corrosion resistant. 3) Good electrical and thermal conductors due to its delocalised electrons 4) Aluminium is a good reflector of visible light as well as heat, and that together with its low weight, makes it an ideal material for reflectors in, for example, light fittings or rescue blankets. 5) Aluminium is ductile and has a low melting point and density. I hope this helps? :)

Aluminum tape is widely used in refrigerator, air conditioning, automobile, petrochemical, bridge, hotels and so on. Application: Aluminum tape is suitable for all kinds of transformers, mobile phone, computer, PDA, PDP, LED displays, notebook computers, copiers and other electronic products in which electromagnetic shielding is required.
Q:How to calculate the weight and length if knowing the width of single layer of aluminum foil,density, diameter of outside roll and diameter of inner roll?
You can calculate the volume by the external diameter, inner diameter and width. the weight can be known by the density and volume, then the weight and length canbe known too.
Q:What to do with aluminum?
* The first step to making money collecting aluminum cans is to find a market for your cans. This can be done by contacting local recyclers and scrap metal dealers. Look in the yellow pages under recyclers, or scrap metal dealers to find contacts. Call each one and see if they purchase aluminum cans from the public. If they do find out their prices as well as their requirements for accepting them. Use this info to find the one that would be best for you. * The next step is to find a place you can store them. The garage or shed would probably be the best place as aluminum cans can attract pests such as ants, wasps, and rodents. They can also have plenty of germs and viruses that you can get sick from. You probably do not want this in your living area. You will also need containers to store your cans in. I just use a garbage can for mine but there are other options as well. If you use a small container like a garbage can you may also want garbage bags for easy removal of cans when full. Then you just tie it up and take it down to your buyer. * The last step is to sell your cans! This is the best part for most of us I am sure.If you have a vehicle you can load it up take them to your buyer. If not you can also use a bike with a bike cart. I do this myself and do fine but you must be in good physical shape. You may find bikes Bike Carts in the ads below. As a tip I would periodically check your buyers buy rate as prices fluctuate daily. Try to sell them when prices are the highest to get the most money. Keep in mind this is not a way to get rich but you can make some money. It take hard work an dediation to be succesful. Hope this help.
Q:What material :ALUMINIUM AGS AFNOR 6060?
AGS may be the manufacturer: Aluminium Glass Manufacturing AFNOR 6060 means the material is defined by the new French Specifications. Aluminum alloys usually have a 4-digit designation. The first digit designates purity or alloy type. The second digit indicates modifications of the alloy. Only in 1xxx series the third and fourth digits indicate the purity. For example, 1050 indicates an aluminum with 99.50% purity. The third and fourth digits in the other series identify different alloys in the group and have no numerical importance. 6060 refers to the class and elemental content of the alloy. The 6000 series means it's a Aluminum-Magnesium-Silicon alloy. Characteristics: (a) medium strength, (b) good formability, machinability and weldability, (c) corrosion resistant, (d) heat treatable. TS could be the solution treatment time. 60-80 HB is the Brinell hardness of the alloy. That was a handful to decipher...hope it helps.
Q:Aluminum corrosion resistance is mainly reflected in what areas?
The second is resistant to salt spray corrosion test conditions generally in the 35 oC, 3% salt spray environment requires 500 hours can not have spots of corrosion. Salt spray corrosion resistance is directly related to the heat transfer sheet length of life. In coastal areas, due to the high salt content in the air, so the heat transfer sheet of salt spray corrosion resistance have high requirements;
