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:which has greater density 5 kg of lead or 10 kg of aluminum
lead it has the Atomic Weight of= 207.2
Q:What advantages does the ceramic panel curtain wall have compared with the aluminum sheet and stone curtain wall?
Now, there are many kinds of ceramic curtain walls. They are made of natural clay materials. They are green, environmentally friendly, low energy consumption, and they are not easy to fade and deform. They have good corrosion resistance and durability, and high strength. At present, the domestic market of ceramic tile is faster than that of foreign countries. I heard ruigao is the first manufacturer of ceramic plate, there are other TOB ah, new Kerry ah. The strength is good.
Q:Do these frames rust? For example here is a link. But I am genuinely curious because in swimming pools, the hand rails going into the swimming pool have the same finish as this bike frame and they have white corrosion marks. Thank you in advanced
Pool handrails are more likely to be made of fairly high grade stainless steel than aluminium, so a different chemistry. And to be picky, rust is a word usually used for steel and iron only. So, while aluminium might not rust, it can certainly corrode, under the right circumstances. People using trainers have reported issues with their sweat doing damage to their bikes for instance.
Q:Hello, I dont really know anything about using a drill or cutting through metal or wood. the thing is I have a project in which I have to drill some holes in 0.04in aluminum. but I really dont know if can use regular drill bits used for drilling wood to drill the holes in my aluminum chassis. do I need to buy other drill bits for cutting metal or can I use the same ones Ive seen used for cutting wood? can I even use the same kind of drills, or do I NEED a huge bench drill with stepper bits?thanks
Aluminum is softer than steel, so you could just use the ordinary bits that you use for wood, with a hand drill. For cleaner holes, you might want to put wood behind the aluminum as a backing. Also, if you squirt a drop of oil onto the drill area, that will help. If you're trying to drill a really large hole, it might be better to drill small ones, and enlarge with a round file.
Q:is general aluminum sheet fire-proof?
nonfireproof
Q:I know that aluminum doesn't belong in the human body. As a canister to hold liquids which will be consumed later, is aluminum good or bad to use?
In my opinion.... Typical plastic bottles with bpa are the worst for you. Aluminum bottles are a step up and great for the environment since aluminum does not require pollutive materials to make and the material itself is not hazardous to the environment like plastic is. Hard plastic bottles without bpa and other harmful materials/chemicals is better for your health as long as it is not exposed to the sun or heat. Stainless steal containers are great to use, but what can be even better?. Water containers that are made out of animals. Example: animal skin, goat bladder. Animal bladders do a great job holding in animal urine, why not use them to hold drinkable water?? You also do not have to worry about any harmful product getting inside your body since animals are 100% biodegradable and they are natural to the environment. When I deploy to Iraq, im going to find a goat and rip out its bladder! Then im going to convert it into a water container for my camelbak!
Q:Dear all, i'm having crack problem with bending aluminium sheet metal, anyone know than which type(Model) of aluminium sheet metal is suitable for bending, Thanks.
Use 3000 series aluminum, it is very bendable. If you use the popular 6061 alloy, it will break or crack nearly all the time.
Q:i need to know these things please....can aluminium withstand the forces of being in a cargo hold on a air freight, can it withstand extreme temps and to what extent an is it microwavable?? please help me
No metals are microwavable, they will ruin any microwave oven by producing sparks. Even ceramic plates with a little metallic paint eg of silver will spark. Aluminium on its own has little strength but when mixed with small amounts of eg copper or manganese it aquires great strength while remaining light. In addition it has the advantage of being very resistant to oxidation and corrosion. It is certainly used extensively in aircraft construction. Due to being non toxic it used to make cans for beers, soft drinks (sodas) etc However it doesn't stand up well to high temperatures, its melting point is just at 660 degrees celsius, by comparison for iron it is 1540 and tungsten 3420.
Q:1. Why does aluminium resist corrosion?2. How do we make aluminium stronger?3. Why does titanium resist corrosion?4. What properties make titanium ideal to use in jet engines and nuclear reactors?5. Why do we need electricity to make aluminium and titanium?6. Why does recycling aluminium save electricity?Even if you only know the answer to one question the help will be much appreciated :D
1. When exposed to air, pure aluminium rapidly forms a passive oxide layer, alumina, which further inhibits aluminium reactions with other elements. 2. Aluminium can be made stronger by alloying with other elements. One of the most known aluminum alloy is duraluminium, where the principal alloying component is copper. 3. Exactly as aluminium, titanium corrosion resistance is due to its high reactivity with oxygen. When pure titanium is exposed to air it forms a passive titanium dioxide layer on the surfaces exposed which further prohibits other reactions with corrosion agents. 4. The use of titanium in jet engines components is favored by its strength to weight ration, which is unmatched by any other metal. As for the nuclear reactors, its use is preferred because of its superior corrosion resistance associated with fracture toughness and overall durability. 5. Both titanium and aluminium are refined from their respective mined ores - bauxite, for aluminium, ilmenite and rutile for titanium. Basically, these are oxides of the metals. Pure metal has to be reduced from these ores and processes involve use of temperatures up to and sometime exceeding 1000 degrees Celsius, which obviously requires a great consumption of energy, including electricity. Moreover, pure aluminium is obtained in the final processing phase through electrolysis, meaning an electrical current is needed in order to drive the required chemical reactions, thus adding to the electrical consumption. 6. Recycling aluminium from aluminium simply requires the remelting of the metal, eliminating the electrolytic phase that is high electric energy consuming.
Q:What is the difference between the alloy 1060H24 aluminum plate and the alloy 1100H24 aluminum plate?
The difference between the two is very small, 1060 and 1100 are 1 pure aluminum plate, H24 aluminum sheet, that is, the degree of hardness!Specific differences are as follows:Series: 1000 series aluminum alloy represents the 1050, 1060 and 1100 series.
