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:Is aluminum foil radiation proof?
According to my own experiments - to wrap the phone up in foil two layers, there was no signal, and the call could not be switched on - the foil was, to some extent, protected against radiation......
Q:Which statement describes a chemical property of aluminum?
The answer is statement 2 Reasons why: First, know that a chemical property of any element is something that results in the change of the chemical make-up of the element. The word for word definition in my textbook says: a chemical property is the ability of a substance to combine with or change into one or more substances through a change in the chemical formula for the substance Looking at all the other options: Statement 1: Whether or not a substance is malleable is whether or not a substance can be hammered or pressed out of shape and not break or shatter. Hammering a substance, or in this case Aluminum, does not change any chemical formula of Aluminum, it just changes the physical shape of the metal. Statement 3: If a substance is conductive of electricity, it means that the material can transport an electric current. This is not chemical because the electricity simply goes through the substance, it does not change or react with any of the atoms of a substance and change the chemical formula. Statement 4: Density is a purely physical property because it is how dense a material is, and it doesn't change the formula of a substance. Therefore, Statement 2 is the best answer because by reacting with sulfuric acid, the chemical formula of aluminum changes since the atoms recombine with the atoms of sulfuric acid and create a new substance and a new chemical formula with it.
Q:Which is good for automobile cover, aluminum foil and DuPont cloth?
Personal feel of aluminum foil is better, if it is summer, the aluminum foil car clothes reflect the ability of the sun, can play the role of regulating the room temperature.
Q:please suggest metal similar to aluminium with casting properties?
It depends on what properties you are interested in. If you want specific answers, you need to ask specific questions. The previous answerers are not very well informed... There are, in fact, many excellent Al based casting alloys. And... cast alloys of brass, pot metal, lead, etc are not very similar to Al (but, again, it depends on specifically what properties you want). Consult your friendly neighborhood metallurgist but think about exactly what characteristics you need to have. The more completely you can define your requirements, the better someone can advise you on the pros and cons of different material selections.
Q:Water heater tube welding seam how
Three, if the defect site is relatively small, can use similar soldering like M51 with M51-F welding wire welding flux, welding the aluminum tube is only suitable for a small trachoma or very small crack, if the crack is much more difficult to weld.
Q:Help. Aluminum uses?
Aluminum is strong ans light weight.
Q:How about the weight calculation of 180 series semi concealed curtain wall aluminum profile
180 series of semi curtain wall aluminum profile weight calculation, usually 15 kg per square meter.Aluminum plating process, which belongs to the coating technology it is pre plating and electroplating process steps to increase on the basis of conventional Ti process, aluminum is the process of the aqueous solution of salt and hydrochloric acid in the plating after activation of chemical treatment; electroplating bath composition including nickel sulfate, nickel chloride, boric acid, twelve alkyl sodium sulfate, saccharin, brightener, this process has the advantages of simple, practical and good effect, the titanium aluminum prepared by the hardness of the film is HV 1500, under the same conditions than the 22 carat gold plating wear 150 times, can be processed into various forms of gold color, color, black light series aluminum products.
Q:Why the printing ink dropped when etching the aluminum foil.
3.We can watching from these aspects: there are dust,silk screen,producing ink and other material.The reason for thin ink
Q:Why the wall insulation aluminum foil is put in the warm side
Putting in the warm side can save the energy and equal to the temperature preservation ratio: In winter,the temperature preservation aluminium is in the interior side of wall in the north.when the temperature of wall rises, the temperature of room is comfortable and the energy consumption is reducing. If putting in the exterior side of wall, the temperature in the room can be risen only after the wall temperature being rising, and the energy consumption is increasing.
