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:are non aluminum grinders better?
Aluminum is a good choice if you plan on using it to grind more than just coffee. Plastic tends to soak up flavors due to oils in coffee, herbs and spices. So if you plan on multitasking metal is the way to go.

Resistivity Of Aluminum Wire
Q:Where is the difference between the 5052 aluminum plate and the 1060 Aluminum plate?
Composition and properties are not the same, first of all, 5052 belong to the alloy (aluminum magnesium) aluminum, aluminum content of about 95%, the magnesium content of about 4%, there are some other trace metals, 1060 pure aluminum (aluminum content of 99.6%, the balance of other metal elements); followed by mechanical propertiesTwo aluminum in the same state, 5052 to 1060 in hardness, elongation, tensile strength and so on are not the same. Specific depends on what state (H14, H32, H24, O state, etc.); finally, because the price of different components determine the price is different, the price is usually 5052 higher than 1060.
Q:Can aluminum plate resist acid and alkali?
The metal oxide film changes the surface state and properties, such as surface coloring, corrosion resistance, abrasion resistance and hardness, and metal surface protection. For example, aluminum anodizing, the aluminum alloy placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, under certain conditions and applied electricity under the electrolysis. Anodized aluminum or its alloy, formed on the surface of alumina thin layer, its thickness is 5~20 microns, anodized aluminum or its alloy. Therefore, the surface hardness and wear resistance of the aluminum alloy were greatly improved by the treatment process.Shanghai Ai Li AI metal materials, dedicated to serve you.
Q:how much aluminium is recycled per year?
45% The fact that they can be recycled to produce more cans means there is no excuse for many people to unaware of aluminum recycling. People should also be aware of the benefits that can occur from it. This has created a strong awareness of the recycling nature of cans and this has been a key factor in the growth of this area. In many canteens, dinner halls and corridors across schools and places of work there is a recycling bin. Wherever people can be found drinking from a soft drink can, a specific aluminum recycling bin can be found for cans to be placed in. Compared to the recycling of many other products, it is easier to find a recycle bin. The provisions for recycling soft drink cans have been more progressively tackled and many people are aware of the need to recycle soft drink cans. This has created awareness and knowledge about recycling and this has moved from school to the outside world. One of the major tactics of marketing departments is to target children and get them to pass the message through to all the family. This is usually done in a bad manner but it can also be done promote recycling. You may see people who go around picking up cans that are thrown away without thought and send them to a recycling center. There are some recycling centers that will make payment for numbers of soft drinks that are recycled. This is a way for people to make some money. It would take a phenomenal amount of aluminum recycling to make a fortune. However, it can help the environment and make a small amount of money back so many people can find the motivation to recycle. There are many places that could be a great source of finding soft drink cans that are thrown away: - School playgrounds - The beach - The car park - Parking lots - Busy streets The amount of products that are available to be recycled continues to grow but it is unlikely that they will grow to be more popular than aluminium recycling.
Q:how to weld cast aluminum?
Let me guess. is your saw made by Chicago Electric by chance? I work as a welder and I tried to fix one of those retarded things a customer brought in, about a year back. The real problem here is a faulty design. Plain and simple. The metal used to make the part is extremely cheap. If you had it welded it would probably cost a bit on labor, and furthermore it's very likely to just break again in the future. See if you can find a used saw made by a name brand, like Milwakee, Delta, or Makita. If it's a tool you use often, then you'll save money in the long run, trust me.

Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
According to metal reactivity series order table, aluminum has a better metallicity, but it will be passivated soon after contacting concentrated sulfuric acid, and won’t react again. But copper and concentrated sulfuric acid can react continually. So aluminum sheet becomes the positive pole after passivation.
Q:a sample of aluminum chloride (AlCI3) has a mass of 37.2 g.?
You have to remember Avogadro's number: 6.02 x 10^23 Read about it in your text book. It is the number of molecules of any atom that make up 1 mole. 1 mole of a molecule is equal to it's atomic weight in grams. So, the atomic weight of aluminum is 26.9. So, 26.9 grams of aluminum contains exactly 6.02 x 10^23 molecules of aluminum (or 1 mole). What's the molecular weight of aluminum chloride? Well, 26.9 + 3(35.5) = 133.4 the 35.5 is the molecular weight of chloride and there are 3 of them. So, 133.4 grams of aluminum chloride would be 6.02 x 10^23 molecules. We only have 37.2 g. 37.2 g/ 133.4 g per mole = 0.279 moles. 0.279 moles x (6.02 x 10^23 molecules/mole) = 1.68 x 10^23 molecules of aluminum chloride. So, since there is one aluminum per molecule, you have your answer. Just multiply by three to find out how many molecules of chloride are present. Finally, if 133.4g = 6.02 x 10^23 molecules, then 1 molecule = 133.4 / 6.02x10^23 = 22.16 x 10^-23 or 2.216 x 10^-22 Make sure that the periodic table you use for class has the same values (some tables are more simplified then others). Also, make sure that you use the correct number of scientific digits when calculating your answer.
