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:Are the aluminum sheets suitable for manufacturing kitchen backsplashes?
Indeed, kitchen backsplashes can be manufactured using aluminum sheets. Aluminum, being a lightweight and durable material, has commendable resistance against corrosion and heat. Moreover, it is effortlessly cleaned and maintained, making it highly suitable for kitchen usage where splatters and spills are prevalent. The versatility of aluminum sheets allows them to be easily cut and shaped to fit any kitchen size and design, providing ample flexibility in creating personalized backsplashes. Furthermore, aluminum contributes a modern and sleek aesthetic, thus imparting a contemporary touch to the kitchen decor. All in all, opting for aluminum sheets as a manufacturing material for kitchen backsplashes is both practical and stylish.
Q:Iron is extracted from iron oxide by displacement with carbon.But aluminum is not extracted from aluminium oxide using displacement by carbon. Suggest a reason for this.
Well, de facto because the heat of formation of aluminum oxide is so much greater than the heat of formation of iron oxide. If you're looking for something more mechanistic, find Al and Fe in the periodic table. Al and Fe are in different rows, and Fe is larger than Al, so although Al+3 and Fe+3 have the same charge, oxygen bonds less strongly to Fe+3 than to Al+3 because it's further away from the nucleus of Fe. Al+3 has no outer shell electrons at all; 3s, 3p, and 3d subshells are all empty. It's effectively a charged sphere with nothing to interfere with bonding. Fe+3 (as in hematite, Fe2O3) is larger, has filled 3s and 3p subshells, and a half-filled 3d subshell. That 3d electron density projects pretty far out into space, holding oxygen at arms length. Aluminum has no electron density in 3d orbitals, so oxygen can tuck in nice and tight and get a good grip. Any of these hit the mark? I don't know what background you're bringing to this question.
Q:I am looking to purchase a pressure cooker and the size that i want comes in aluminum while alot of the others are made from stainless steel. I am wondering if the metal makes a difference in the funtionality and if one doesn't stand up as well as the other.
Hi.. Choose the one you like. Because, there is no much difference with Aluminum and Stainless steel pressure cookers in either cooking or in weight (you must have seen the weight when you went to the store). But the Stainless steel pressure cooker will be little bit costly than the aluminum one. The pitting inside of the cooker can be prevented if you clean and dry it after each and every use. You should not keep water at the bottom of the cooker for a long time. Any pressure cooker will lasts longer if we follow proper precautions/instructions as per the use and care guide. If we speak about Gasket and Pressure valves, you need to change the gasket once in every year if you use the cooker regularly (depends on the usage) and pressure valves should be replaced as needed for any pressure cooker. I am cooking in pressure cooker from 12 years. Had to throw away my first one 'coz lack of proper care. And now, i am using my second one from 8 years twice a day. There are lot of stainless steel pressure cookers probably because they are also upgraded (from aluminum to stainless steel) like every thing else.
Q:Aluminum plate 90 degree bending, why cracking?
There are several reasons why the 180 degree bending of aluminum plate causes cracking: 1. The bending edge is parallel to the rolling direction of the aluminum plate, so it is easy to crack and turn the bending direction to 90 degrees. 2. 180 degrees bending angle is too much to be greater than the minimum
Q:What are the different methods for joining aluminum sheets?
There are several methods for joining aluminum sheets, depending on the specific application and desired outcome. Some of the common methods include: 1. Welding: Aluminum can be welded using various techniques such as Tungsten Inert Gas (TIG) welding, Metal Inert Gas (MIG) welding, and Resistance Spot Welding (RSW). TIG welding is commonly used for thin aluminum sheets, providing a strong and precise joint. MIG welding is suitable for thicker sheets and offers faster production rates. RSW involves passing an electric current through the sheets, melting the aluminum at the contact points, and then applying pressure to create a solid joint. 2. Mechanical Fasteners: Bolts, nuts, and screws can be used to join aluminum sheets together. They provide a strong and reliable connection that can be easily disassembled if needed. Rivets are another common mechanical fastening method, where a rivet gun is used to secure the sheets by deforming the rivet. 3. Adhesive Bonding: Specialized adhesives designed for aluminum bonding can be used to join sheets together. This method is often used when aesthetics are important, as it provides a clean and seamless appearance. Adhesive bonding also distributes the stress evenly across the joint, reducing the risk of localized stress concentration. 4. Clinching: Clinching is a cold joining process where a punch is used to deform the aluminum sheets, creating a mechanical interlock. This method is quick, cost-effective, and does not require additional materials like fasteners or adhesives. 5. Friction Stir Welding (FSW): FSW is a solid-state joining process that uses a rotating tool to generate friction between the aluminum sheets. The friction heats the material, making it pliable, and the rotating tool then stirs the softened material together to form a solid joint. FSW is particularly suitable for joining thicker aluminum sheets. Each joining method has its own advantages and disadvantages, and the choice depends on factors such as the desired strength, appearance, production rate, and the specific requirements of the application.
Q:What are the physical properties of aluminum sheets?
Aluminum sheets possess various physical properties that make them highly desirable in numerous applications. Firstly, aluminum sheets are lightweight, with a density of around 2.7 grams per cubic centimeter, which is about one-third that of steel. This characteristic makes aluminum sheets easy to handle and transport, reducing overall weight in structures or products. Aluminum sheets also exhibit excellent corrosion resistance due to the formation of a thin, protective oxide layer on their surface when exposed to air. This oxide layer acts as a barrier, preventing further oxidation and corrosion, making aluminum sheets suitable for outdoor applications and environments with high humidity or exposure to corrosive substances. Furthermore, aluminum sheets have good thermal conductivity, allowing them to efficiently transfer heat. This property makes aluminum sheets commonly used in heat exchangers, radiators, and other cooling systems. Another important physical property of aluminum sheets is their high electrical conductivity. Aluminum is an excellent conductor of electricity, second only to copper, making it widely used in electrical applications such as wiring, power transmission lines, and electrical equipment. In terms of appearance, aluminum sheets have a bright, silvery-white color and a smooth surface finish, giving them an aesthetically pleasing look. They can be easily shaped, formed, and machined, making aluminum sheets highly versatile and suitable for various manufacturing processes. Overall, the physical properties of aluminum sheets, including their lightweight nature, corrosion resistance, thermal conductivity, electrical conductivity, and ease of fabrication, contribute to their widespread use in industries such as aerospace, automotive, construction, and electrical engineering.
Q:Can aluminum sheets be easily shaped or bent?
Yes, aluminum sheets can be easily shaped or bent due to their malleability and low density.
Q:Can 101 aluminum sheets be used in food storage containers?
No, 101 aluminum sheets should not be used in food storage containers. Aluminum sheets, commonly known as 101 aluminum, are not food-grade materials. They are typically used in industrial applications such as roofing, construction, and electrical wiring. Food storage containers need to be made of food-grade materials that are safe for storing and preserving food. It is recommended to use containers made of stainless steel, glass, or food-grade plastic for food storage to ensure the safety and quality of the stored food.
Q:Are aluminum sheets suitable for architectural louvers?
Yes, aluminum sheets are suitable for architectural louvers. Aluminum is a popular material choice for louvers due to its various advantageous properties. Firstly, aluminum is lightweight yet strong, making it an ideal material for architectural louvers. It can withstand external forces such as wind and weather conditions without compromising its structural integrity. This is crucial for louvers, as they need to provide ventilation and airflow while also maintaining their shape and functionality. Secondly, aluminum is highly resistant to corrosion and rust. Louvers are often exposed to outdoor elements, including rain, moisture, and sunlight. Aluminum's resistance to corrosion ensures that the louvers will remain durable and long-lasting, even in harsh environmental conditions. Additionally, aluminum is a versatile material that can be easily customized and fabricated into various shapes and sizes. This allows architects and designers to create louvers with unique designs and configurations to suit specific building requirements.
