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 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:How to clean the engine oil and kerosene on the surface of aluminum sheet?
it will disappear after rubbing with petrol.
Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
Q:Aluminum plate 90 degree bending, why cracking?
Should be the aluminum sheet material and the state of the wrong, I do not know what brand of aluminum plate, with 1060 Aluminum plate, the state: soft 90 degrees bending, not cracking
Q:how to process 0.3mm hole on aluminum material?

Q:The difference between aluminium alloy and aluminium plate
Aluminum Alloy is a kind of nonferrous metal structural materials widely used in industry, has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industry. In recent years, with the rapid development of science and technology and industrial economic structure, increasing demand for Aluminum Alloy welding, the welding of aluminum the alloy also further widely used. Aluminum Alloy promoted the development of welding technology Aluminum Alloy, at the same time the development of welding technology and expand the application field of Aluminum Alloy, so Aluminum Alloy welding technology is becoming the research hotspot. A Aluminum Alloy: aluminum based alloy in general. The main alloying elements copper and silicon, magnesium, zinc and manganese, minor alloying elements such as nickel, iron, chromium, titanium, lithium and so on.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
you can use deburring brush,grinding fluid,abrasive powder and other consumables.
Q:How well does aluminum hold up in chlorinated pool water?
Aluminum is not a good choice, even if it's anodized, painted, or powder coated. Pool water is corrosive mostly due to the chloride from chlorination. Steel is slightly less prone to corrosion. Plastic or fiberglass is the best choice.
Q:which has more mass lead or aluminum?
The density of ANY amount of lead is greater than the density of ANY amount of aluminum. So even if we have a tiny speck of lead, and a truckload of Aluminum the lead still has greater density. The density of a substance does not depend on how much of it we have. One drop of water have a density of 1g/cm^3 and an ocean of water have exactly the same density of 1g/cm^3. The only difference is that the drop of water has less mass than the ocean, hence it would be easier to fetch; and the drop also has less volume hence it takes up less space.
Q:What bonds can Aluminum make?
Aluminum forms metallic bonds in the metal and aluminum alloys. Aluminum forms covalent bonds as with aluminum isopropoxide. Aluminum forms ionic bonds as in aluminum sulfate. Aluminum chloride is ionic in aqueous solution but molecular in solvents such as benzene.
