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[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:Why would you put an aluminum foil in the oven?Just this?
2. package ingredients grilled and flavoredThe food package into the aluminum foil barbecue, such as Butter Crab, fried clams, fresh and sweet flavor of the ingredients can be locked!Aluminum foil paper generally smooth and fog. Fog is easy to heat, so it should be facing the fog photothermal, will play the effect. Therefore, the barbecue, aluminium foil bright surface, fog wrapped food facing charcoal, meat easily cooked.Note: if using aluminum foil wrapped food barbecue, not in the aluminum foil drops of lemon juice and other acidic substances, because the aluminum foil is metal, when the metal and acid mixed together, chemical changes may occur, easy to produce harmful substances.
Q:Can aluminum foil paper be put 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:aluminum boat repair?
You just pulled off the cheap repair - that had failed or you wouldn't have had to. As the problem wasn't fixed correctly the first time it now is that much harder to repair. The rivets are structural, if they are completely stuffed, and the original holes far too spread out you are looking at riveting Through stainless washers, or even a sandwich of aluminium sheet, with sikaflex or similar between as a gasket - silicon is no good. If you don't weld or rivet the repair you are not going to return the hull to original strength. No amount of gloop and caulking can make a boat - or boat hulls would be built from it. I have seen marine ply used to repair and alter aluminium pressed hulls - but really there is not much difference in cost and effort. If the splits are really big you might consider investing in a small MIG welder to do repair patching - but if you build up one area too much it will only focus the stresses of that section elsewhere, probably leading to quick failure in adjoining areas. If you prep the hull yourself and clearly mark the areas that need welding, take the hull inverted to an alloy welder it will only cost a few tens of dollars to get them buzzed up - it is the prep time that costs with any tradesman. So the cheapest repair is to do it right using rivets and aluminium plate and stainless washers and weld as needed. You should get a two handed rivet gun - the one handed ones are really hard on the hands when they pop. You also will require high quality drill bits and goggles - be prepared to break a couple of bits should the metal move or the bit catch on an angle. I always buy a heap of the double end type and if I break one, flip it and keep going. It is perfectly normal practice to go up a size in rivet to get a firm contact, I also use Duralac to prevent electrolysis between the slightly different alloys. Good luck.
Q:a chunk of aluminum is at 220degees C is thrown into water that is initially 50degrees C?
(A) Let the aluminum is of m kg, than :- =Q(gain) by water = Q(loss) by aluminum =m x s(water) x delta t*C = m x s(aluminum) x delta t*C =50 x 4187 x (100 - 50) = m x 897 x (220 - 100) =m = 97.25 kg (B) Let the amount of water boiled off is m kg =Q(loss) by aluminum = Qwater(50*C to 100*C) + Q100*C(water to vapor) =500 x 10^-3 x 897 x (220 - 100) = 50 x 4187 x (100 - 50) + m x 2257 x 10^3 =m x 2257 x 10^3 = -10413680 =No water will be boiled off as the energy provided by aluminum is less than required to raise the temperature of water to 100*C.
Q:Should I prime aluminum?
Aluminium MUST be primed using an acid etch primer, else the subsequent coats will flake off. Use 'Finnigans Hammerite Special Metal Primer', from Homebase / BQ.
Q:How can I remove the grease when the aluminum foil is punched? 5
The key problem is in the stamping oil, using volatile and good lubrication effect of stamping oil, 140 degrees drying. See if your supplier is willing to pay for it
Q:How to remove the adhesive sticker in aluminum foil bag?
Wipe it with alcohol or liquor with higher concentration.
Q:Need a good aluminum bodied RC helicopter?
aluminum okorder.com... if someone else finds another chopper, don't blame me, i'm human.
Q:How to identify between magnesium and aluminum.?
they wont use magnesium parts in motor vehicles as it is very brittle in nature and is easily broken. NO the test you mentioned is wrong. Identification test for magnesium involves precipitation with ammonia.
Q:Which is stronger, lexan or aluminum?
Lexan is similar to polymethyl methacrylate (Plexiglas/Lucite/Perspex) and is commonly described as acrylic in appearance, but is far more durable, often to the point of being described as bulletproof (depending on the thickness of the sample and the type of weapon used). Aluminium is a soft, lightweight, malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminium is nontoxic, nonmagnetic, and nonsparking. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is ductile, and easily machined, cast, and extruded. In Chemical series, Aluminium is termed as poor metals therefore, Lexan is stronger than Aluminium in all aspects
