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:I am looking to purchase a pressure cooker and the size that i want comes in aluminum while alot of the others are made from stainless steel. I am wondering if the metal makes a difference in the funtionality and if one doesn't stand up as well as the other.
Hi.. Choose the one you like. Because, there is no much difference with Aluminum and Stainless steel pressure cookers in either cooking or in weight (you must have seen the weight when you went to the store). But the Stainless steel pressure cooker will be little bit costly than the aluminum one. The pitting inside of the cooker can be prevented if you clean and dry it after each and every use. You should not keep water at the bottom of the cooker for a long time. Any pressure cooker will lasts longer if we follow proper precautions/instructions as per the use and care guide. If we speak about Gasket and Pressure valves, you need to change the gasket once in every year if you use the cooker regularly (depends on the usage) and pressure valves should be replaced as needed for any pressure cooker. I am cooking in pressure cooker from 12 years. Had to throw away my first one 'coz lack of proper care. And now, i am using my second one from 8 years twice a day. There are lot of stainless steel pressure cookers probably because they are also upgraded (from aluminum to stainless steel) like every thing else.
Q:what were the cinergy field (riverfront stadium, cincinnati, oh) seats made of? were they metal or aluminum? i know they were silver under the red paint...
If Cinergy isn't the concentration of the drawing, it particularly is probable in simple terms th at they have not as much as date the drawing of the skyline. If there's an indicator on the packaging layout, then removing the stadium might require them to resubmit the trademark utility, and that they probable do no longer evaluate it relatively easily worth the difficulty.

Q:Its been bugging me for years and i want to know why they say aluminum and not aluminium like it is spelt in the Oxford English dictionary and more importantly the universal periodic table, accepted by all countries, does anyone know why? I would like all opinions on this matter, if possible, thank you
Aluminum okorder /... It’s clear that the shift in the USA from –ium to –um took place progressively over a period starting in about 1895, when the metal began to be widely available ... The American Chemical Society only adopted it in 1925, though this was clearly in response to the popular shift that had already taken place.
Q:My understanding of the periodic table, the transitional metals all rust because the S shells are higher energy then the D shells. So all transitional metals have 2 valence electrons. (Roughly...some electrons like to move around and give different apparent charges.) So why does aluminum corrode if it doesn't have a 2+ charge?
'Rusting' commonly refers to the corrosion (oxidation) of iron so when talking about other metals, it is better to use the term 'corrosion' or 'oxidation'. Aluminum can corrode and the fact that it has a general oxidation number of +3 doesn't really matter. Many elements which have a charge that is different from +2 can oxidize. Alkali metals for instance (which have a charge of +1) can oxidize. Lithium can form lithium oxide (Li2O), sodium can form sodium oxide (Na2O) and so on. However, aluminum is known to be quite resistant to corrosion (oxidation) because it spontaneously forms a thin (solid) oxide layer at it's surface protecting it from further oxidation whereas iron, for an example, will easily lose that thin layer (it ''peels off easily'') exposing more iron to corrosion. So since Al has a +3 charge and O has a -2 charge, you'll need 2 atoms of Al and 3 atoms of O to make an electrically neutral compound. 2 atoms of Al = +6 charge 3 atoms of O = -6 charge Hence Al2O3 which is aluminum oxide. I hope it helps.
