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 want to make a small pork loin roastMaybe 2 or 3 lbsEnough to feed one person for a week or soI plan to rub it with onion and garlic powder, then cook it for half an hour at a high temperature and several hours more at a very low temperatureI have a 9 by 13 nonstick cake panWill that work? Or should I buy a disposable roasting pan? Also, should I cover it with aluminum foil at any point during the cooking process? I don't want it to come out dryI've never made roast pork before, only roast beefAny advice would be appreciated!
- I live in the Dallas area and recently had an energy audit done by my power companyOne of their recommendations was R40 attic insulation.
- Q:Can you tell me how to get number of valence electrons?Im in 8th Grade can you tell me in small words im not that stupid though but can you tell me how to tell it step by step.I need to find Number of Valence Electrons of Aluminum tell me what the Valence electron and how to do it.
- Valence electrons are the electrons in the shell furthest from the nucleus(the last shell)Aluminum has 13 protonsTwo protons fill the first shell, eight fill the second shell, and three fill the last oneThat uses up all 13 protonsAluminum has 3 valence electrons(the 3 electrons in the final shell)Keep in mind you can only put two protons in the first shell, and eight in the other shells.
- Q:I'm in a science fair project I didn't ask or want to be in and I need informational help. My project was to test different materials to see if they block radio waves. Aluminum foil was one of them and it is the only material that blocked radio waves. Now to the point, I have to type this part called ''Application''. It is how any gained information from this project can apply to the world or help real-life situations. The only thing I learned from this project is that aluminum foil blocks waves because it is an electrically conductive metal that can reflect and absorb radio waves and that every technological device or machine needs radio waves to work. But how can this help world situations ?! Who would want to block radio waves in real life? Everyone needs or probably wants radio waves! How can this be applied to the world?! Please help! It is taking me forever to get through this section of the project and I'm seriously almost done!!!!
- Some devices don't use radio waves, a CD player for example. Radio waves are flying around everywhere, and can interfere with some of the sensitive singals inside these devices, so we want a way to block the waves. Some devices produce radio-waves, not as an intended output of the device, but as a byproduct of another function. Your computer is an example of this. And these devices can interfere with the operation of devices that are close by, like your cell phone. So we want to stop these accidentally produced waves from getting out of the computer. And sometimes a part of a device uses radio waves while another part of the same device doesn't, and must be shielded from the other part or it won't work properly.
- Q:im making cookies in a toaster ovenhow would i go about doing that- and what do i put them on? just the rack/shelf thing or do i need a sheeti don't have any baking sheets just tinfoil i think.
- Look for what's called Fan-Fold (typically blue but can be pink) It usually is in 4'x50' sections and has an R3 value I would also suggest you cover it with a house wrap to make it air tight before you attach the siding.
- Q:4 fish filets, totalling about 1 pound 1/4 cup heavy cream 2 small zucchini 1 lemon 1 bunch of chives salt and pepper Preheat the oven to 400°FCut four pieces of aluminum foil, about 15 inches long each oneWash the zucchini and cut it in thin slicesChop the chives finely and put them in a small bowlSqueeze the lemon, adding the juice to the chivesMix in the heavy creamPlace each filet on top of its piece of aluminum foilSalt and pepper the fish lightlyPlace the zucchini on top of the fish, evenly dividing it amongst the four piecesPour one tablespoon of the cream mixture on top of each filetWrap up each filet in its aluminum foilYou can roll the top edges to make sure everything is secure, but be careful not to tear the aluminum foilPlace the four packages in an oven proof dish and place the dish in the ovenCook for 20 minutesServes four.
- If you will explain the part or parts that aren't clear to you maybe someone can help It makes sense to me and i don't see what you are finding tricky or difficult to make you not get itI tried to see if maybe some part was confusing or vague but it is a really easy recipe to meYou enclose the filets in the foil by making a sort of tentBring the two pieces together at the top and kind of roll the foil down and crimp the ends to make sure nothing sloshes outSo give yourself a nice (but not huge) amount of foil to work withGive us a little more info and we can see if anyone can help you.
- Q:I want some Vegetarian recipe which I can make in Foil Packets.I'll give 10 points for the best one.
- I make a recipe called Poor Man's Meal I usually use ground Turkey, burger, fish or chicken but you can ulinate the meat if you want toMake each foil packet a serving sizeAdd whatever vegetables you like with or without meat, top with butter and salt/pepperFold packets upI always wrap twice so the juices don't leak outToss on grill turning often until veg are tender!!!
- Q:I want to make a dress from aluminum cans. However, aluminum is very sharp once cut. So, do you thing there is a possible way to make the cut edges less sharp? Would sanding the edges help?
- Or you could just curve them to the back or front a bit by hand, or roll them over a dowel, etc, for more of a curve but maybe easier to do. You could also try sanding or filing them (electric sanders/etc would be best but wear eye protection and a mask to keep metal dust/bits from getting to you). Or you could also paint each edge with something like ModPodge, white glue, polyurethane, etc, all of which would dry clear (or dip each edge into a tray of one of them)...or you could use acrylic paint but that would be colored. Or you could put tape over the edge (but more time consuming). Or just connecting the cans could help, whether you'll be connecting them with lacing through holes, etc, or the edges of some glued/taped overlapped on other cans.
- Q:On Valentines Day, my boyfriend and i woke up together.i made him a gorgeous heart shaped box covered in pictures of usi also made him chocolates!unfortunately, i put spray lacquer on the box waited as long as i could for it to dry then wrapped each chocolate in aluminium foil and put them in the boxwhen we went to eat them they tasted like lacquer and we swallowed the chocolatenow he is freaking out because he thinks we've been poisoned but it was 3 days ago, i don't know how to calm him down, and the fact that we both have loose stool doesn't helpso if anyone knows if quot;harmer crystal kote glossquot; fumes can poison someone from ingestion can you let me know?
- It is doubtful that you received too much fumes, but your loose stools could be caused by too much chocolate! if you are functional enough to use the computer, then you probably have NOT been poisonedBut you DO need to be sure that you are drinking LOTS of water - diarrhea can cause dehydration, which can be VERY seriousStill, it would be a good idea to throw away any remaining candiesNext time, plan ahead, and do the spraying AT LEAST one week before you use the box.
- Q:25 ml of 10% solution is taken and added into 50 ml waterFurther 10ml Bacl2 (20%) is added in itIt will make milky solution,add some drops of phenophthaein indicator, heat it to boiling point so as to remove chlorine from it Now titrate it against 0.25N (NaoH)Measure the volume at which the milky solution turns into pinkish Multiply the volume with 0.1696 and this will give %age alumina in aluminium sulphate.PLEASE CHECK WHATS WRONG WITH THIS PROCEDUREOR IF HAVE SOME OTHER METHOD TO CHECK ALUMINA PLEASE HELP.
- There are a few things that don't sound right in your explanation: First of all, refluxing the solution won't get rid of chloride ions and you certainly don't have a strong oxidant to be forming chlorine gasYou should scratch this explanation from your report because it makes no senseSecond of all, when BaSO4 precipitates to leave behind aluminum, the Lewis acidity of that ion is strong enough to undergo multiple deprotonationsIn fact, in neutral or slightly alkaline solutions you end up forming Al(OH)3: [Al(H2O)6]3+(aq) - 3 H3O+(aq) + Al(OH)3(s) The heating is only to ensure completion of this processThird of all, phenolphthalein changes color when the solution changes from acidic to basic (pH ~ 8.0)Therefore, NaOH neutralizes all three equivalents of acid produced by aluminum before the indicator turns pink: 3 H3O+(aq) + 3 NaOH(aq) - 3 Na+(aq) + 3 H2O(l) what this means is that to get the moles of aluminum present in solution, you have to divide the number of moles of NaOH by 3.
