Product Description:

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).



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 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:The applications of aluminum foil
Scrap aluminum foil can be used to make poly aluminum chloride which is a common kind of inorganic polymer flocculants. The broad sources of raw material for manufacturing poly aluminum chloride lay the foundation for its development, especially the diversity of production processes which provides convenience for the development of poly aluminum chloride. International and domestic manufacture and application has scaled up and theory research has gained further development. Manufacturing material mainly include bauxite, aluminum hydroxide and waste molecular sieve catalyst. Manufacturing methods mainly contain wet process and electrolytic process. As some scholars think scrap aluminum foil has high economic value for recycling, they research the best conditions to produce poly aluminum chloride with scrap aluminum foil and the range of application for purifying water via experiments. With the development of industry and the rapid growth of urban population, water pollution is increasingly serious, which lead to more sewage to purify and more purifier to meet the increasing demand. As poly aluminum chloride molecule has different quantities of hydroxyl, it will hydrolyze under the PH condition of the source water and be accompanied with a series of physical and chemical process like coagulation, absorption and deposit after adding poly aluminum chloride to the turbid source water to purify the water. There is a wide source for scrap aluminum foil mainly from the package of cigarette, food and medicine, whose main component is aluminum, so it has high economic and social value to recycle scrap aluminum foil. The best conditions to produce poly aluminum chloride with scrap aluminum foil and the range of application for purifying water have practical significance for the increase of resource utilization rate and environment protection after test and research.
Q:mesohigh electronic aluminium foil
Q:Can aluminum foil paper be used in microwave oven?
Yes. But not all aluminum foil can be heated din the microwave oven. Microwave oven for specialized use is available in the supermarket. It can control temperature to evenly heat the food and prevent nutrition loss. I often use it when making beer fish. aluminum foil fall into aluminum foil for high-temperature cooking and for low temperature cooking. When putting the food wrapped with aluminum foil into the microwave oven, the contact of aluminum foil with inner wall will cause sparks. Therefore, please use it with caution.
Q:How to remove the adhesive sticker in aluminum foil bag?
1.smear facial oil onto it, then dig it with your finger and finally wipe it with a wet towel. 2.using hair dryer, waiting the glue to become hot and then you can get it down. 3.using the essential balm and it will be off a few minutes later. 4.You can use a eraser. In the beginning, you may find it become dirtier, but if you continue, you may find that it works. 5. put it into water, then put a little detergent, and finally use an old toothbrush to brush it. 6. use a cloth dipped in alcohol or wipe it with alcohol. 7.Using a sodium water or paint thinner to wipe it. 8. using cotton swab with nail polish remover to wipe 9.Put a piece of paper soaked in vinegar, and then gently put it on the two-side glue, waitting three or four minutes, giving the double-sided adhesive enough time to absorbe, and then gently take it away.
Q:Between Aluminum foil fibre cloth tape and pure aluminum foil tape which one is good?
It only depends on what fields do you want to use it? If it is used in explosion-proof, strapping, it is suggested that you can use fiber cloth aluminum foil tape. If considering heat conduction, electric conduction and shielding performance, it is suggested that you use the pure aluminum foil tape.
Q:What's the aluminum sheet and its features?
After been hot-rolled and cold-rolled, aluminum slabs with a thickness of above 0.3mm can be called as aluminium plate or aluminium strip(with a rolled shape); with a thickness of less than 0.3mm can be called as aluminium foil or aluminium foil strip(with a rolled shape). Aluminium foil is usually made of the type 1 or type 2 industrial aluminum. Aluminiym foil has all features of metal aluminium. Heat conduction, gasproof, light insulation and electromagnetic radiation shield are all important features.
Q:Can you tell me how to use aluminum foil grill ?
People used to put food on the frosting side, but it turns out that the shiny side is better, for the shiny side can reflect heat while the frosting with rough surface loses heat. While grilled with the shiny side up, the heat is constantly reflected so that the food can be cooked as soon as possible. If you wrap up the food with the shiny side, the heat is kept inside. It is energy-saving.
Q:what's the dying temperature of aluminum-foil paper?
It depends on walking speed.If faster, 180 degree,otherwise 120 degree.
