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:Is Aluminum really stronger than steel?
It depends on how you set the criteria of comparison. If you go by volume, Aluminum isn't stronger. That's why a steel can is stronger than one of similar size and thickness. If you go by weight, aluminum is said to be stronger. Let's say we were looking to create a wall, spec'ed to a particular height and width, and just thick enough to hold back a given PSI of pressure. The aluminum one would have to be thicker to have the strength to hold back the pressure, but it'd be lighter than the steel equivalent. Also, the ease by which a material can be nicked isn't an indicator of strength but of hardness. Harder, isn't necessarily stronger.
Q:Aluminum wiring in house preventative measures - ceiling lights?
There's no problem with aluminum wiring that would require you to rewire your house as long as the proper wire gauge was used. You should replace all of the receptacles and switches with ones rated CO/AL. For lighting, replace the wirenuts with ones rated CO/AL and you'll be fine. From what I remember, Aluminum has a higher resistance than copper so it requires 1 size larger conductors. Aluminum also oxidizes faster than copper. If you have aluminum wires in your panel you should turn the main service disconnect off and put some de-oxidizer (you can find it at home improvement stores in the electrical section) where the wire lug is. This oxidation can make a bad connection causing you to lose voltage as the resistance goes up raising the amperage. This will generate more heat. Aluminum also... well its hard to explain... A/C current cycles its power in a sin wave, it causes the wire to vibrate. You will have to tighten all of the lugs on your electric panel periodically. The CO/AL wirenuts and receptacles/switches help prevent the vibration from loosening the connections causing a short and possibly a shock hazard or even a fire.

Q:Aluminum foil and aluminum foil is the same?
Thousands of tons of aluminium foil are used around the world for the protection and packing of food, cosmetics and chemicals.
Q:What does it mean to slice aluminum coil by decoiler machine?
The operating procedures of decoiler machine: 1, Select appropriate aluminum coil according to production work order requirement to be processed, paying attention to the thickness, width and material of aluminum coil. 2, Put the aluminum coil into the coil loading car with traveling crane and inch the car into the uncoiler. The aluminum coil and decoiler machine should be in the same direction. Hold the aluminum coil down with leading head, and open the auxiliary bearing. 3, Turn on the shovel head, and inch the uncoiler to lead the aluminum sheet into the leveler. Adjust the leveler according to the thickness and width of aluminum sheet to ensure the flatness. 4, Turn on the front gap bridge and back gap bridge in control main platform, inch the leveler to lead aluminum sheet into re-leveler. Adjust the re-leveler to ensure the flatness of aluminum sheet. Put it into the shear gauge and plate shearer. 5, Take back the front and back gap bridge. Inch the plate shearer to cut off the sheet head and shear the aluminum sheet according to production work order. Check the first sheet to see whether it meets the quality standard and whether there is defect in flatness, length, diagonal, and surface of aluminum sheet. If it is qualified, turn on the conveyor. Put the aluminum sheet holder on the pallet. Adjust the pallet according to the width and length of aluminum sheet. Input quantity and length on the control main platform. Then turn on the auto control to produce automatically. The production process can be observed at any time. 6, If there is aluminum coil left, unwind, package and put it into storage in reverse steps.
Q:What is air conditioning aluminum foil?
Air conditioning is gradually to small, high-performance, high-life direction. The air-conditioning heat exchangers and thin sheet corresponding to the high strength direction. 1980 heat sheet thickness 0.15-0.2ram, and now only the thickness of between 0.09 to 0.15mm.
Q:How can you invest wisely in aluminium stocks?
I am just a student, so I wouldn't advise you to do more than confirm what I'm about to tell you with a licensed investment adviser before acting upon it. Firstly, the price of aluminium does impact the performance of the aluminium company's stock. This relationship, however, is not perfect and depends on the individual characteristics of the company. The relationship is more pronounced in companies that focus on only one element of production, such as extraction, as opposed to those that diversify their operations into other activities along the production line like refinement, etc. Secondly, about the input costs, sure they do affect metal producers (each differently from the next) as they do many other industries. However, the prices of metals and other commodities are likely to rise with any unanticipated inflation that may arise as a result of the current state of oil prices. So much so that that the effects of the oil price spike may be ignorable. Thirdly, in my opinion one year, is a short-term investment. In the long-term, however as long as your company survives I expect that it will do fine, meaning it may well be profitable. Volatility, however is a natural thing to all investments, but the risk-free ones and a premium is paid to all investors to compensate for this volatility, or risk as it is commonly called. What really matters at the end of the day is the long term trend, which is unknown but generally assumed to be positive. Lastly, if you really want to invest in the aluminium industry I suggest that you ask around about any Exchange Traded Fund or some other well diversified investment vehicle with a focus on Aluminium Producers or Aluminium itself. That would certainly be a safer way to participate in the Aluminium Industry, than investing in a single company.
Q:How many applications does aluminum foil have?
Q:aluminum elements question?
Aluminum is element 13, so it has 13 protons. This also means that it normally has 13 electrons (provided it is not in an ionic state). Normally it has 14 neutrons, but may have less or more in various isotopes.
Q:Would alternating layers of Aluminium, Polymers, Styrofoam, and ER Armor be good for tank?
Aluminium has a strength up to 800 N/mm2 (for its best Al-based alloys) while steels can go much higher... about 1400 N/mm2 if I recall well. The problem with aluminium is that is prompt to fatigue break which is not good with something vibrating like a rolling tank armor. Polymers are not strong enough unless you use composite materials, for ex. fibre glass or even better - carbon fibre reinforced. The problem is still that unlike steel, the strength is exceptionally high... in one direction - so pray for the impact to be mostly from this direction.
