Product Description:

Aluminium coil 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 coils 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 coil 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:How to identify the quality of color coated aluminum coil and sheet?
Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
Q:How to calculate the dosage of paint for aluminum coil coating? If the weight is 1 ton, the density 2.71 and the thickness 0.12mm, how much paint is needed?
Coating surface area S*0.12(thickness)*ρ(density) / solid(paint solid)=actual paint consumption brush and roller paint: 100% spray paint: calculated value*70%
Q:How to use aluminum sheet to roll a 12m-long aluminum coil with a diameter of 184cm?
According to project experience, first you should check the specification of the aluminum sheet and then design crafts such as connection method, installation and transportation according to equipment.
Q:Why 5052 turn black after annealing during the production of aluminum alloy?
The aluminum oxide in the surface has been oxidized by other chemical elements.
Q:How many 1220mm*2440mm aluminum sheets can one-ton aluminum coil be sliced to? Thank you.
You should know the thickness of aluminum sheet first, and then calculate the weight of aluminum sheet of this specification, and finally use 1T divide the weight.
Q:Why there is arc panel after aluminum coil straightening?
The aluminum coil can only become flat and straight after being planished on stretch bender.
Q:Why do the layers loose when taking out coil after roll of aluminum 0.14?
After rolling, the most possible reason may be poor deoiling effect. I think, for 0.14mm aluminum coil, the lining sleeve will not be forgotten. After rolling , oil ooze from aluminum layers, and the support of aluminum coil is not enough, leading to coil collapsing. The specific manifestations are that the edges of even round aluminum layers become like water ripple, and that the aluminum coils suddenly become uneven when taking out coil.
Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
Q:How much does it cost to use fluorocarbon paint for aluminum coil roller coating?
Fluorocarbon paint can be divided into fluorocarbon paint for exterior wall, aluminum fluorocarbon paint, metal fluorocarbon paint and steel structure fluorocarbon paint according to usages. It can also be divided into national standard product and non-national standard product according to industrial standards.
Q:How to deal with too much aluminum powder in aluminum striping?
Currently, there are bag dust-removal system and water dust-removal system. The former is very popular with enterprises because of low maintenance cost, accounting for over 90%. But the problem is the dust accumulation because the ventilation and dust removal systems are not produced in strict accordance with the standard. For example, controlling wind speed does not meet the requirement; ventilation and dust removal system does not meet the requirements of explosion-proof, including the set of pipes, series and parallel connection, the choice of dust removal system, the spark detection and extinguishing measures.
