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:steel motors and aluminum motors?
Aluminum dissipates heat better than steel but I never had trouble with my '55 Panhead. Maybe it was colder temps in the 1970's.
Q:Is there a tool or technique for bending aluminum plate?
a brake press but be careful. Some types of aluminum have a grain and it will split. Also if the radius is to tight, it can fracture from stress. 1/4 aluminum is pretty strong, but you can use 1/8 and just make the bracket longer. Then you should be able to bend it quite easily on a roofers brake or manual box and pan brake. If all else fails, and it is just for home handy man use. You can use a vice and clamp it tight, on the other side clamp a piece of ply wood to distribute the force and then tap it down with a mallet. (not a hammer) You dont want to leave tool marks so the ply wood will help Do not make the bend to sharp, do not bend to quickly with a mallet or it also may get stress fractures (about 8 to 10 strikes should do it) I am curious, why aluminum. Steel has a higher tensile strength and its easier to work with .
Q:Is aluminum foil a heat conducting material or an insulating material?
Aluminum foil is made of aluminum, the thermal conductivity of aluminum is very high, about 200 or so, it is a better thermal conductive material
Q:Why is hydrophobic aluminum foil used in air-conditioning bad performance?
Hydrophobic aluminum foil above the water, the water will always hang on the foil, relatively speaking, reducing the air flow between the aluminum foil, so that the heat exchange rate decreased. Therefore, the air-conditioning is used "hydrophilic foil", as soon as there is condensed water flow away, does not affect or as little as possible affect the heat exchange rate.
Q:What is the advantage of Cast Aluminium Cookware?
forged aluminum concts warmth with out postpone and is usually slightly thicker tan much less costly SS for greater even warmth distribution. Stailess will stay bright and you may use greater abrasive scrubbers while mandatory. no longer all cookware has Al. previous post is possibly refering to laminated cookware. some are Al. clad on the backside and a few like my wifes Kitchenaide form are SS with Al. coated in SS. The thicker the backside the greater even the warmth combating warm spots.
Q:Can microwave oven use aluminum foil?
Absolutely not. The main raw material in aluminum foil is aluminum. In the microwave oven, there will be a phenomenon of sparking and damage to the circuit
Q:Is there some harmful side effect of using aluminum as the boiler in a still?
Aluminum can be toxic in very high concentrations, but using aluminum as cookware (or still-ware) is very unlikely to cause toxicity. The only time aluminum may cause a problem is when cooking tomatoes or highly acidic foods in untreated aluminum cookware. Even then, the level of aluminum that gets cooked off into the food is negligible. It's better, however, to make sure that the cookware you are using in the still is food safe. Copper may be a better choice, but I'm sure that's more expensive. Hope this helps. You may want to check your local area to see if there's a home-brewing supply, or a beer-makers supply company and they may be more helpful about a good container to use for the boiler.
Q:Do subs sound better with aluminum or metal cones?
Aluminum is a type of metal, so if I had to guess, the metal ones you are seeing are aluminum as well.
Q:What is aluminum foil tape?
This tape weather is good, but also more resistant to low temperatures, in a complex climate, especially at low temperatures still able to maintain excellent performance, quality change, the same shape, viscosity, and adhesion is kept first class.
Q:Is it bad to burn aluminum foil?
This Site Might Help You. RE: Is it bad to burn aluminum foil? so my family had a barbeque today and my mom put a sheet of aluminum foil over the grill to cook the chicken. i was wondering if the aluminum foil would burn and give off some sort of unhealthy chemical. is this true or am i just being paranoid?
