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 features of corrugated aluminum sheet is light weight (only steel 3/10), silver white and other colors, both decorative effect, but also a strong ability to reflect sunlight. It can fire, moisture, corrosion resistance, can be used in the atmosphere for more than 20 years. Relocation dismantled corrugated board can still be reused. Aluminum corrugated sheet is widely used in building decoration. It is suitable for hotels, restaurants, shopping malls and other buildings walls and roof decorations.

Corrugated aluminum sheet is made of aluminum alloy rolled sheet, its wavy cross section, is currently building a new type of building material widely used.
Only one-third of the proportion of aluminum steel, and has good ductility, very suitable for rolling process, in addition to aluminum also has a strong corrosion resistance, and therefore have important applications in the construction industry.

Aluminum and oxygen in the air after the chemical reaction, the surface will generate layer strong and dense oxide film. This layer of aluminum oxide film preservation became "coat", the internal aluminum is difficult for them to oxygen in the air to oxidation, so aluminum is placed in the atmosphere a year, which is less than the depth of corrosion of thousands of hours one millimeter. If the same time into the aluminum and steel containing 3% of sodium chloride and 1% of the hydrogen chloride in the container, the corrosion test of 70 hours, the average weight loss of steel per square centimeter 11.07 mg in weight loss of aluminum average of 0.675 milligrams per square centimeter, which proves the corrosion resistance of aluminum is generally much higher than the steel. However, the natural oxide film of aluminum, there are still shortcomings thin and soft, corrosion is not very strong, so that the service life of corrugated sheet aluminum untreated generally only about 20 years. If aluminum by chemical oxidation (i.e., at a certain temperature of the aluminum oxide surface cleaning and liquid oxygen in a chemical reaction) or electrochemical oxidation (i.e. the aluminum into the electrolyte, in the role of the applied current and oxygen ions the method of a direct reaction of water with aluminum surface cleaning) are processed, on the surface of the aluminum layer will generate 0.025 to about 0.05 millimeters thick and hard and even more some of the oxide film, so as to further improve the corrosion resistance of aluminum performance. After aluminum corrugated sheets thus treated, the service life of up to 60 years. Aluminum corrugated sheets can also be a variety of bright colors, it is possible to make the building more beautiful.
Lightweight aluminum corrugated board, use it to do the roof, asbestos-cement tiles per square meter than about 20 kg lighter. Aluminum is easy to implement plastic molding, rolling aluminum corrugated sheet length is unlimited, so use can reduce the number of joints, thereby increasing coverage. In addition, the high strength aluminum alloy corrugated board, use it to make building materials, particularly useful in earthquake-prone areas.
In short, aluminum corrugated board is a light weight, high strength, fire, beautiful, shock, easy transportation and construction many advantages such as excellent building materials.

Q:To rephrase- in our physics class we found that a simple bar magnet wouldn't attract to an aluminum gutter nail, but our teacher told us to find out whether or not any magnet could lift up the aluminum material. If you answer please give a reference or source, or at least an idea on how to go about researching this, all help appreciated, thanks and God Bless!

Q:What are the semi hard ones? What are the alloys? What are the anti rust ones, such as 3003505210606061, 7075?
Three 3000 series aluminum representing 30033003 3A21. Also known as China's 3000 series aluminum antirust aluminum production process is more outstanding.3000 series aluminum is made of manganese as main components. The contents of 1.0-1.5 in between. Is a series of anti rust function better. Routine application in air conditioning, ice box, car etc. in the moist environment, price more than 1000 series, is a commonly used alloy series.Four 4000 series aluminum on behalf of the 4A01 4000 series aluminum plate belongs to the high silicon content series. Usually silicon content between 4.5-6.0%. Belongs to the building material, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance of the product description: has the characteristics of heat resistance, wear resistanceFive series of 5000 representative 5052.5005.5083.5A05.5000 series is a commonly used aluminum alloy aluminum series, the main elements of magnesium, magnesium content in 3-5%. Also called aluminum magnesium alloy. The main characteristics of low density, high tensile strength, elongation rate is high. In the same area under the weight of the aluminium magnesium alloy is lower than that of the other series. It is commonly used in aviation, such as aircraft fuel tank. The application in the conventional industries are more widely. The processing technology for slab continuous casting and rolling, which belongs to the aluminum plate series so can do deep processing of aluminum oxidation. More mature system in our country in 5000 series aluminum one.Six series of 6000 representatives of 6061 mainly contains two elements of magnesium and silicon, so the advantages of 4000 series and 5000 Series 6061 is a cold forging processing of aluminum products, suitable for applications in corrosion resistance, oxidation resistance requirement. Use good interface features excellent, easy coating, processing is good. Can be used for low pressure weapons and aircraft joints.
Q:I had this mandarin orange can. I filled the can with water. Four days later, there are quarter inch thick rust cakes on the inside of the can. Since I assume the can is aluminum, are these cakes aluminum oxide? If so, is it flammable and/or dangerous?
Mandarin orange cans are not generally made of aluminum. Most likely, it is steel with a tin coating on it. Aluminum oxide does not turn red, most likely this is iron oxide, otherwise known as rust metal oxides are not flamable. Heavy metals are hazardoues (lead, lead oxide...), but iron oxide is not, in fact, it's important to have iron in your diet, it is what makes your blood work! Astrobuf
Q:I was watching an old Star Trek movie. The last one with the full original cast; where they bring two whales into the future. There is a scene in which Scotty and Bones are trying to get material to build a giant tank to hold the whales inside the Klingon space ship. They go to a manufacturer and offer him the formula for Clear Aluminum in exchange for the materials. Scotty and Bones don't know who invented Clear Aluminum and the manufacturer who will eventually place the patent in the 20th century didn't really invent it, so who did? If you think of this as a thought experiment would this prove that other universes exist? Did Scotty and Bones create a new universe?
Nichols was eventually recognized as the inventor of transparent aluminum.
Q:1100 scope of application of aluminum plate
1100 aluminum plate is generally used in utensils, heat sink, caps, printing plates, building materials, heat exchanger components, but also can be used as deep stamping products. It is widely used in various fields ranging from cooking utensils to industrial equipment
Q:I heard somewhere that when aluminum is heated, it releases something that is a known cause of Alzheimers. Is this true? I have a homemade cooker made of aluminum and I don't want Alzheimers.
Yes it's true. The same toxins can also be absorbed through the skin from the aluminum in our deoderant.
Q:A 0.2412 gram sample of aluminum ore was dissolved in a dilute mineral acid. The solution was treated with an excess of sodium oxalate. The resultant aluminum oxalate precipitate was filtered, washed and redissolved in mineral acid, then titrated with 42.12 mL of 0.1098 N KMnO4. Calculate the percent of aluminum in the sample.

Q:i keep hearing all these things about burning aluminum foil and such
Yes, aluminum is a soft metal andit will not hold up well in a fire and if it's a hot fire you don't want to breathe in any fumes the rim might give off. If you want to use a rim, best to use steel. Or like the other guy said, rocks or bricks.
Q:I don't know if the electrons are being passed from my hand to the aluminum or from the aluminum to my hand.Thanks
Aluminum is a metal and a good conductor of electricity. If you touch it, it will get grounded, so it will be neutral. You cannot charge a metal up by touching it with your hand unless you are not grounded yourself. If you are standing on a piece of plastic, say, then it will take whatever charge is on you. If you are positive, it will become positive. If you are negative, it will become negative. But you must be insulated from ground to do that. If you are touching the ground then any charge on the aluminum will just flow out of the metal through you to ground and the aluminum will stay neutral
Q:We just bought a house with aluminum wiring and we knew about it in the inspection report, but everyone kept telling us it's no big deal. There was so much going on and I didn't look into it myself and now I just surfed the web on it and I am filled with anxiety! Please help! Did we make a huge mistake? How common are the dangers? Also, my insurance company didn't ask me about wiring, but some sites said that they don't cover aluminum wiring. Should I ask them? I am so overwhelmed and scared. I do not want a fire for my family!
All of these answers are good. There is a concern. I would suggest that if there is a question of security -- that you slip ( or get an electrician) to slip each switch and outlet out of the wiring box and tighten the connections. As for the racoons, there are simple and pretty much low cost (under 30 bucks, voltage sensors at your local electrical supply, and maybe at Home-Depot. These really nice devices sense the presence of AC electricity in the wall, even locating the actual point where the electricity stops at a break! This is a do-it=yourself project.
