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).

Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
It’s useless. Aluminum foil will generate eddy and emit heat after medium induction, which will reduce the thermal efficiency of medium frequency. Now I provide a method for reference only. Induction coil will be water cooling and is packaged by thermal cement and other materials. Use asbestos sheet and other materials to transform the both ends of induction heating coil as baffle which is mobile and convenient for load and unload. When steel tube is heated in the induction coil, you can put down the baffle to prevent large loss of heat, shorten heat time and improve heat efficiency. When the seamless steel tube is heated into setting temperature, you can open the baffle to conduct expanding process, and you don’t need to think about the thermorytic problem of steel tube in the expanding process. It’s important to shorten the time of expanding process. Baffle is used for heat retaining of medium frequency heating and extrusion forming in our factory. The method above for reference only.
Q:Do aluminum cans melt in typical campfires? I know the melting point is about 660 Celsius but do campfires get that high? I thought it would just be that the can becomes disfigured and collapses due to the heat, not due to it melting. Even if it did melt in the fire how would you find the remains? The can in a liquid form would certainly not be confined to one part of the fire and therefore wouldn't solidify in a small pool to see if it had melted or not. Any ideas?
A campfire does not get hot enough to melt Aluminum.
Q:I have tried every possible method that I could find on the web for cleaning aluminum, tungsten, filler wire. Nothing has seemed to work. I've tried looking for leaks in the argon line. I'm getting decent welds but there is gunk in the welds for sure. I'm worried about overall strength of the welds. Does anybody out there know of a tried and true method for cleaning aluminum, tungsten, filler etc. that is sure to work? If I can follow that method and still have problems It could possibly be a problem with the machine. Any help would be much appreciated.
Preweld cleaning requires two operations: oil/grease removal and oxide removal. As below, remove oils and greases first, then remove the oxide. Don’t reverse this order. Take the following steps before welding aluminum: 1. Remove oil, grease, and water vapor using an organic solvent such as acetone or a mild alkaline solution like a strong soap. You may also use citrus-based degreasers, but be sure to rinse and dry the part before welding. 2. Remove surface oxides with a stainless steel wire brush (used only for aluminum) or strong alkaline or acid. Many welding suppliers sell oxide-removal solutions in spray or squeeze bottles for local application. Exercise extreme care when handling these solutions, and again, rinse and dry the part before welding. 3. Assemble the joint. If it won't be welded immediately, cover the joint with brown Kraft paper to prevent dirt and grit in the air from getting into the joint. 4. Keep the aluminum dry and at room temperature. 5. Weld within a few days. Clean the joint again if it isn't welded within that time. Good luck!!!
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:Dear all, i'm having crack problem with bending aluminium sheet metal, anyone know than which type(Model) of aluminium sheet metal is suitable for bending, Thanks.
THERE WERE MANY TYPES OF ALUMINUM ACCORDING TO ITS RIGIDITY. Please refer to RS Industrial catalogue for your data references.
Q:heating can affect aluminium
This is science so, if you want specific answers, you must ask specific questions. What type of aluminum are you interested in? What characteristics are important to you? What kind of factors are you talking about? You are right that heating can affect Al. In fact, heating affects, basically, everything, every material we know of and every physical and chemical process that we do and every process that happens in nature. Temperature is important in all of these. There are more than a hundred different commercial aluminum alloys and most of them are available in a variety of different tempers (heat treated conditions). The heat treatment of commercial Al alloys is a very important thing. If you want more specific information, consult your friendly neighborhood metallurgist.
Q:write a balanced equation for the reaction between aluminium metal and potassium hydroxide in water
So convert 27,8 g iron to moles, and convert that to a mass of aluminium 2. 3 CuNO3 + Fe3+ -- Fe(NO3)3 + 3 Cu+ 3. 2 Fe3+ + 3 O2- --- Fe2O3 So convert Fe2O3 from 20,8 grams to moles. Multiply this answer by two. Convert to a mass of Fe3+ 4. H2SO4 + 2 KOH -- K2SO4 + 2 H2O again, 150 grams of H2SO4 to moles, then convert that amount to an amount of mass of K2SO4 5. Na2CO3 + 2 H3O+ + Cl- --- CO2 + 3 H2O + NaCl
Q:Everyone said that the pre roll coated aluminum plate, what is pre roll coating?
Beforehand, beforehand, mean,Roll coating is a paint coating process, relative to spraying, such as powder, wall coating, coating or roller coatingThe coating is applied to the surface of the aluminum sheet by a roller or steel roller. Roll coating
Q:What is made when Aluminium and Hydrochloric Acid reacts? It makes a dense white smoke with a metallic odour in the gas. Could it be dissolved amounts of Aluminium Chloride or small amounts of unreacted Aluminium in the gas? Or could be that the Chlorine (in equilibrium with HCl and HClO) made chlorates and perchlorates of aluminium that give off odours?Don't tell me the gas isn't supposed to have an odour. I know what diatomic Hydrogen smells like. Nothing. That's the way it should be. But unfortunately, that's not the way it is.
i might call the plumber immediately. curiously there's a hollow interior the piping someplace, and the sulfuric acid would desire to have eaten by in spite of advance into clogging that hollow. I doubt that it will supply up leaking via itself, to no longer point out that acid is in all risk leaking into your kitchen in the present day.
Q:aluminum is produced by breaking down the compound...
Bauxite is the most important aluminum ore. It consists largely of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH), and diaspore α-AlO(OH), together with the iron oxides goethite and hematite, the clay mineral kaolinite and small amounts of anatase TiO2. You have an unusual way of asking that question. Aluminum is an element and cannot be broken down accept to sub-atomic particles.
