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:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:Why does fillet appear when rolling aluminum coil?
How thick and wide is it when there is such problem? Which is the rolling pass? And what is the type of the rolling mill? The simple 4 rollers or CVC and HC rolling mill with roller control. Does the filler appear in rolling or out of roller? Different thickness will lead to different analysis.
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.
Q:How much will be burned out if the soaked and oxidized 5182 aluminum coil is melt down and reprocessed?
Burn out rate is generally between 1% -2.5%, but that varies among plants as their actual situations are different.
Q:What are the compositions of aluminum coil coating?
The common compositions are crylic resin, solid inorganic filler, different pigments, flatting agent and so on.
Q:Can aluminum coil 3003H24 replace 3A21H14?
It is ok in some way as both of them are alumal. The hardness of 3003H24 is similar to that of 3A21H14 after hardening without annealing. Both have good corrosion resistance, plasticity and bad machinability. They cannot be used as load bearing parts even though small load is ok. They cannot be anodized.
Q:How is the welding performance of 3003 aluminum coil?
3003 aluminum coil, a kind of rust-proof aluminum, belongs to AL-Mn series alloy. With low intensity (slightly higher than commercial purity aluminum), it cannot endure heat treatment, so cold processing is adopted to increase its mechanical property: high plasticity in annealing and semi-cold hardening, low plasticity in cold hardening, good corrosion resistance., good weldability and bad machinability. It is mainly used for low load part in liquid or gaseous medium requiring high plasticity and good weldability, such as fuel tanks, gasoline or lubricant conduit. It can also be used for liquid containers and other deep drawing small load parts made by deep drawing. Aluminum wire can be used to make the rivet.3003 aluminum sheet has good formability, weldability and corrosion resistance. It is used to process parts which require good formability, corrosion resistance and weldability and lower intensity than 1xxx series alloy, such as such as kitchenware, food and chemical products processing and storage equipment, groove and tank to transport liquid product, pressure vessel and pipe processed from thin plate, cooling fin, make-up board, photocopier rollers and ship material.
Q:Can aluminum foil coil be stores for a long time?
It is ok within one or two years, but for five or six years, it will be oxidized.
Q:How much is the rust-proof and thermal insulation aluminum coil?
3003 alumal alloy is the best and common rust-proof and thermal insulation aluminum coil. The price depends on the thickness and width you need.
Q:Is there aluminum coil of 44mm wide and 0.40mm thick?
The common width of aluminum coil is 1000mm or 1220mm. If you want 0.4mm*1000MM aluminum coil, you can strip 0.4mm*1000MM aluminum coil.
