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:Making Flash paper from ceramic aluminum oxide sandpaper?
Flash paper is not made with flash powder. Flash paper is paper that's been nitrated. The easiest way to make it is to get some nitrocellulose, pour it onto a sheet of glass or other flat surface, wait for it to dry and then scrape it off. It'll dry into a thin sheet that you can light and it'll burn just like flash paper. I do not suggest making flash powder. It's both friction and static sensitive and even a small unconfined amount can blow off your fingers. It's really not worth it.
Q:Aluminum vs. steel?
I swear with the aid of an all aluminum trailer! Aluminum over steel next, and that i'm hoping I in no way very own yet another steel trailer! I even have had trailers for, shall we see, 40 years now, and in simple terms bought my first aluminum one approximately 6 years in the past. it truly is 14 years old and apart from some bumps that WE put in it (the comparable quantity of bump could have dented a steel trailer too) it truly is in large shape. a 10+ 3 hundred and sixty 5 days old steel trailer exhibits a marvelous form of positioned on and tear, and should be sanded and painted in many situations.
Q:Advice on how to solder aluminum?
a soldering iron or gun. use a low melting solder. it comes in various grades. go to Menard's or Home Depot they have it.
Q:Is there any chemical reaction between carbonated mineral water and aluminium cans?
Aluminium cans have an oxide covering on them so the reaction between them and the carbonated water is so little if any that it can't be noticed. Aluminium is also not so high on the reactivity series
Q:Specific heat capacity of aluminium...?
This is not my expertise. As I have been researching this the past hour to re-educate myself, no one else has answered you. So, I will attempt to get you in the right direction by what I found. I found two specific heat values for Aluminum. The recent one is from wikipedia with the other an old text someone quoted. The specific heat of aluminum, cAl, is 0.897J g−1 K−1; this is, 0.214cal g−1 °C−1. [per wikipedia] AND The specific heat capacity of aluminum as 0.215 kcal/(kg C) [The Handbook of Chemistry and Physics, p. D-217, 1979]. Standard Value was the harder item. I found it is referred to as Hro [Where the o is a circle]. I could only find it referring to water. To measure heat for each metal, it was always compared to the heating water, which is used as the standard. I'm guessing its like a thermometer filled with mercury. The mercury gets heated and the lines are marked to tell you how hot the air is. Hope that helps... Maybe someone else will jump in...
Q:Aluminum foil's not magnetic, but it reacts to charged objects. Why is this?
Aluminum is a non-ferrous metal. Ferrous metals contain Iron which is magnetic. When aluminum has a charge applied to it, it acts like any conductor would, the charge has magnetic properties. the aluminum is still not magnetic, but it acts like a magnet due to the charge.
Q:Is aluminum powder lead?
Aluminium and lead are two different elements - they're not the same thing. (Aluminium is the stuff that soft drink cans are made of.) But i would watch out for aluminium as well. There is a small amount of evidence that aluminium might be linked to Alzheimers and things like that. It's much *less* of a risk than lead, but generally metal powders are not things that you want in your body, if you can avoid it.
Q:Is aluminum a hard metal for a ring?
Aluminum is a quite soft metal, but so is gold. It is true that aluminum is light in weight but magnesium is even lighter and is common enough that a ring could be made of it. Metals can be made harder by adding small amounts of other metals or even by the way it is heat treated. .
Q:question about aluminium foil paper?
It isn't the foil that is burning you--it's the water. Aluminum foil is a good heat conductor. This means that when you expose the foil to the air, it will cool off very rapidly (rapidly reaching room temperature). Water is NOT a good heat conductor, in fact, it likes to hold onto it's heat. So while the dry foil may come to room temperature (or just warm to the touch) in a few seconds, the water will stay hot for much longer (depending on how much water there is obviously). It's really the same as trying to grab a baked potato wrapped in foil off of the grill. If you grab the potato you will burn your hand (because the potato is holding A LOT of heat), but if you carefully peel away the foil, you can touch and take the foil off with your bare hand. I should say that the mass of the foil also plays a role here. The foil is not very massive and thus does not hold a lot of raw energy to begin with (also because it's a good heat conductor it dissipates quickly). Bu if you put an aluminum can (or a brick of aluminum) in the oven, I guarantee that it would stay hotter for much longer than just a piece of aluminum foil.
