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.

Q:Why can't I melt aluminum?
www.okorder.com/.. its doesnt burn burn u knw.it just becomes sorta britte.it becomes oxidised...u can got more infro there.try..i read it just now
Q:Calculate Number of Aluminium ions ?
The formula for aluminium oxide is Al2O3 Its molecular weight is 2*27+3*16= 54+48 =102 Now, 102g of Al2O3 contains 2*6.023*10^23 number of Al ions so 1g contains (2*6.023*10^23)/102 number of Al ions so 0.051g Al2O3 contain (2*6.023*10^23)/102 *0.051 number of Al ions which is equal to 6.023*10^23*10^-3 = 6.023*10^20 number of Al ions(Answer)
Q:Aluminum vs Carbon road bike frame?
Ride them both. You will like the aluminum bike, but you will fall in love with the carbon. New carbon frames are very light, stiff, road dampening, and responsive. You have to stand on the pedals only once to know they fly. They have a Cannondale lifetime warranty against cracks. Just a note about the component set. 105 is nice. Ultegra is so smooth. I would pony up for the Ultegra on the carbon frame. There IS a feel difference, not just weight savings. Have fun with either.
Q:Aluminium recycle- Essay?
kind of random but i saw at kmart that coca cola makes dish clothes and sheets out of there recycling.
Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal, aluminum sheet will directly contact hydrochloric acid, generating H2.
Q:Doesn't the acidity of soda drinks dissolve aluminium cans?
because they are light and easy to smash with your hand
Q:Is it true that heated aluminum causes Alzheimer's?
They felt that used to be the case because of the aluminum seeping into the food. Hard to find an uncoated aluminum pot now. You get more aluminum from deodorants and antacids than cookware. You shouldn't though cook or store tomatoes in aluminum...and that's just the reaction in chemistry.
Q:Is there aluminum in tin?
no, tin is tin it's one of the periodic elements.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
Q:What is the density of the 1100 aluminum plate?
1100 aluminum plate is generally used in utensils, heat sink, caps, printing plates, building materials, heat exchanger components, but also can be used as deep stamping products. It is widely used in various fields ranging from cooking utensils to industrial equipment.
