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: Can anyone tell me what to be careful of if you have aluminum wiring in your house. I was told that if the wall gets hot, I need to tighten the screws of the inside switch. Is this true and if I didn't, would it actually cause a fire in the wall. If this is true, how often does it loosen?
- Several answers are very good but the one thing that evrybody failed to mention is each device (switch, recept, fixture, etc.) must be listed to use with AL wire. This is the biggest problem I find. Home owners run out to the local hardware and pick up a new device and do not check the listings. The copper wire pig tail is an option but once again you must use a wire nut that is listed for both AL CU wiring. Most are a dark purple in color. Electrical Inspector
- Q: A hollow aluminum tube (diameter 4.50 cm) is sealed at one end and loaded with lead shot to give a total mass of 0.163 kgWhen the tube is floated in pure water, what is the depth, z, of its bottom end?
- I have Omaha Steaks and exotic meats etc shipped all the time, they come through Fed Ex or Ups and it is sent in a cooler with dry iceI never have a problemSo place cake in a box, box in a bag (you don't want dry ice to seep in) and this goes into a cooler with dry iceNow typically, if you are driving in an air conditioned vehicle and keep the cake in a box out of direct sunlight, it should be okBut, go with my idea to be on the safe side.
- Q: Will it be okay to just skip the covering?
- Place a piece of aluminum foil over the top of the panRun your fingers around the edge of the pan to form a tight sealWould be best if the foil was doubled to make it thickerYou could also try placing another pan on top of the one you are cooking the rice inWeight the top pan down so there will be no gapsIf you do this you might want to put a kitchen towel between the two to seal off any gaps.
- Q: Can aluminum coils be used for electrical conductivity purposes?
- Yes, aluminum coils can be used for electrical conductivity purposes. Aluminum is a good conductor of electricity and is often used in various electrical applications, including coils for transformers, motors, and generators.
- Q: How to shape, bend, and engrave Aluminium?
- Well, you need to give us a little more info for us to answer thisWhat did he look like in the casket because if he was bruised he probably was beaten to death, but if he was bent up and had blood or places there were blood, he was probably in a car accident or shotTell your hubby about the dream if you already haven'tLet him reassure you that everything is okI hope this helps.
- Q: I heard if you put foil on your windows it will keep it cooler , but won't it catch fire with all the heat?
- Or try Bitter AppleIt comes in a spray sold at most pet storesIt tastes horrible so most animals will avoid it but its harmless.
- Q: This question asks for the method to determine the weight of a steel coil.
- <p>To calculate the weight of a steel coil, you need to know its length, width, and thickness, as well as the density of the steel material. The formula to calculate the weight is: Weight = (Length 脳 Width 脳 Thickness) 脳 Density. The density of steel is approximately 7850 kg/m鲁. Convert the dimensions to meters if they are not already in that unit. Multiply the volume (length 脳 width 脳 thickness) by the density to get the weight in kilograms. For example, if a coil is 2 meters long, 1 meter wide, and 0.005 meters thick, its weight would be (2 脳 1 脳 0.005) 脳 7850 = 78.5 kg.</p>
- Q: I want to make a craft and want to know how to create the illusion of lightfor e.gI want to make a 3d pumpkin most likely out of paper, but want it to seem like it's glowing from inside as if candlebut without an actual battery powered light bulb or anythingis there any way to create the illusion of light? such as aluminum foil painted yellow to look like light or some other trick? thanks.
- try the aluminum one I can't really say anything else, you need a reflector.
- Q: A science-fair radio uses a homemade capacitor made of two 50 cm X 50 sheets of aluminum foil separated by a 0.20-mm-thick sheet of paperAssume dielectric constant of paper is 3.0.What is its capacitance?
- C 50 x (er x eo x A)/d Where 50 is the number of sheets A 0.5m x 0.5m 0.25 m^2 d 0.2mm 2 x 10-4m C 50 (3 x 8.85 x 10^-12 x 0.25)/2 x 10^-4 C 1.66uF
