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 Lightweight Durability of Aluminum Sheets
In the 1970's, there was a large-scale movement for beverage companies to stop using steel cans for soda pop and beer. Their existed the need to switch to an alternative material that offered lower cost in production, thus the aluminum can was born. Once word was out that aluminum weighed less, cost less and was recyclable, beverage companies were on board very quickly and the change became permanent. Today, aluminum, especially aluminum sheeting, is used for more industrial applications than ever before.
As a low-cost material that is both tough and lightweight, aluminum sheeting has been used across many industries for a number of years. In contrast to steel, aluminum weighs less than steel. Aluminum is cheaper to manufacture, and easier to bend into a variety of shapes. It can be shipped easily (less weight=less cost), and makes many items lighter in weight (cars, airplanes, etc.). Aluminum is also stronger and weighs less than tin, making aluminum a more cost feasible product.
The sheeting is available in a variety of grades. Each grade is manufactured with specific designated usages. Certain grades contain a combination of alloys to reinforce strength and/or chemical resistance; while other grades are heat-treated structurally, in order to maintain its resistance to corrosion. Commercially pure aluminum sheeting is generally regarded as the most chemically and weather resistant, but is not as strong as aluminum alloy grades.
Aluminum sheeting also comes in different thicknesses. In the manufacturing process, pre-treated aluminum ingots are passed through heavy rolls under massive amounts of pressure. The more pressure that is applied, the thinner and longer the aluminum becomes. Aluminum ingots can pass through many series of rollers to achieve their required gage, or thickness. Aluminum sheeting of any grade or alloy can extend from 0.006 inches to 0.080 inches thick. Any gage that is thinner than a gage of 0.006 is considered to be aluminum foil; whereas anything thicker than 0.080 is considered to be a metal plate.
- Q: Are there any limitations on the width-to-thickness ratio of aluminum coils?
- Yes, there are limitations on the width-to-thickness ratio of aluminum coils. The specific limitations depend on various factors such as the intended application, manufacturing process, and the mechanical properties of the aluminum alloy being used. Generally, a higher width-to-thickness ratio can result in increased material instability, difficulty in handling, and potential quality issues. Therefore, it is necessary to carefully consider these factors and consult industry standards and guidelines to determine the appropriate width-to-thickness ratio for aluminum coils.
- Q: What do the two items (COIL:873347 HEAT: number) on the label of the raw material of aluminum coil stand for?
- COIL means aluminum coil and HEAT means heating, so together they mean hot rolled coil.
- Q: Is it possible to recycle aluminum coils?
- <p>Yes, aluminum coil can be recycled. Recycling aluminum is a highly efficient and environmentally friendly process. It requires only 5% of the energy needed to produce new aluminum from raw materials. Recycled aluminum coils can be used to manufacture new aluminum products, reducing waste and conserving resources. The recycling process typically involves melting the aluminum, which can then be reshaped into new coils or other forms. This makes aluminum one of the most recycled materials in the world.</p>
- Q: To put aluminum heads on my car do i have to add other things or basically can i just get them and put them on
- Aluminum heads will warp the first time the engine accidentally overheats. Why would you go with aluminum?
- Q: Explain the distinction between standard and non-standard aluminum coils, focusing on their specifications and applications.
- <p>A standard aluminum coil is manufactured according to specific industry standards, such as thickness, width, and alloy composition, making it suitable for common applications like construction, automotive, and packaging. Non-standard aluminum coils, on the other hand, are tailored to meet unique customer requirements, featuring customized dimensions, alloys, or finishes that deviate from the norm. These are often used in specialized industries or for specific projects where standard coils do not meet the necessary specifications.</p>
- Q: Are there any specific guidelines for the handling of aluminum coils?
- Yes, there are specific guidelines for the handling of aluminum coils. These guidelines typically include proper lifting techniques, the use of appropriate equipment such as cranes or forklifts, and ensuring that the coils are stored in a clean and dry environment to prevent corrosion. It is also important to handle the coils gently to avoid any damage or deformation.
- Q: Can aluminum coils be used in electrical cables?
- Electrical cables can indeed incorporate aluminum coils. Aluminum is widely utilized as a material for electrical conductors due to its exceptional electrical conductivity and comparatively lower cost when compared to copper. Its usage is particularly prominent in power transmission and distribution cables that necessitate long-distance transmission. Overhead power lines and underground cables often employ aluminum coils. However, it is crucial to acknowledge that aluminum possesses a lower tensile strength than copper, requiring careful design and manufacturing of the cables to ensure sufficient mechanical strength. Furthermore, achieving the same electrical performance with aluminum conductors necessitates larger cross-sectional areas compared to copper, potentially resulting in slightly larger cable sizes.
- Q: Can aluminum coils be used in the production of aluminum honeycomb panels?
- Yes, aluminum coils can be used in the production of aluminum honeycomb panels. Aluminum honeycomb panels are made by bonding aluminum sheets to a honeycomb core material, usually made of aluminum as well. The aluminum coils are typically used to produce the aluminum sheets that form the outer skin of the panels. These coils are rolled into thin sheets and then cut to the desired dimensions before being bonded to the honeycomb core. The use of aluminum coils allows for efficient and cost-effective production of aluminum honeycomb panels, as they can be easily formed and processed into the required shape and size. Additionally, aluminum is a lightweight and durable material, making it an ideal choice for the production of honeycomb panels used in various industries such as aerospace, construction, and transportation.
- Q: What are the different thickness tolerances for aluminum coils?
- The specific grade and application of aluminum coils can cause variations in their thickness tolerances. Generally, the standard range for these tolerances is typically between +/- 0.002 and 0.015 inches. Consequently, the actual thickness of the aluminum coil can differ within these limits. The specific tolerance requirements may also be affected by factors like the manufacturing process and the intended use of the coil. Therefore, it is crucial to refer to industry standards and specifications to ascertain the necessary thickness tolerances for a specific application.
