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.

Q:Bike Spokes: Brass vs Aluminum Nipple Difference?
Well, in reality you can't tell just by looking. Aluminum nipples are generally only found on superlight race wheels rather than run-of-the-mill stuff. Brass nipples are hardly ever gold colored- they are usually chrome plated or black while aluminum and plain steel nipples can be just about any color. Aluminum nipples are VERY soft compared to brass and will strip and fail in the hands of the amateur builder or repair person. UNfortunately, this is the best way to determine whether a nipple is aluminum or brass while on the wheel- when it fails due to poor skills or overstressing the wheel.
Q:Which aluminum roll is good?
Complete product specifications, quality assurance, brand strength has very good cutting characteristics of Gaoyang welding, the main products are pure aluminum, aluminum alloy, aluminum pattern, Japan Sumitomo mirror aluminum, aluminum and other materials imported from South Korea, widely used in home appliance industry, stamping, sheet metal production, decoration, curtain wall, automobile industry, mold processing.

Q:The difference between pure aluminum foil bag and aluminized foil bag
if the two materials are shined under the light, the pure aluminum bag is transparent while the aluminized bag is silver white and the brightness of aluminum foil is weaker than the aluminized bag.when touching the two types of bag, the aluminum foil bag is a little hardness while the aluminized foil bag is soft and has the ductility.

Pouring sand into the aluminum tube, the two ends are blocked and then the bend will not deformWith lead? Where do you go for lead?
Q:Anti-perspirant without aluminum chloride?
I have thoroughly researched this, as I have been wanting the same thing and was going to post this exact question myself. After A LOT of research, I have learned that aluminum and all aluminum based chemicals in antiperspirants are what keeps us from sweating. Therefore, they all have it, it is just a matter of what percentage. I found a posting by Dt. Stephen Z. Fadem, MD, FACP. He is a member of the AAKP Medical Advisory Board. He claims the the FDA came to a conclusion that aluminum is safe when used according to the directions. I have my doubts on this. The American Cancer Association found inconclusive evidence that the aluminum in antiperspirants is related to breast cancer. I am frustrated by this as well as I need antiperspirants too. However, I learned that if you switch to just a deodorant, your armpits still sweat, (as this is a natural way for your body to get rid of toxins, but gross), but not as much. I have also learned that if you don't allow your body to get rid of the toxins in this manner, some toxins are stored in a gland near your breasts and this one of the ways that many people believe you get breast cancer. There are several other places that your body sweats out toxins as well, including behind your knees. Sorry I couldn't be more help, but unfortunately, there is no such thing.
