- Q: 1 ton of aluminium=______ tons of Alumina
- Aluminium is a reactive metal and it is hard to extract it from its ore, aluminium oxide (Al2O3). Direct reduction, with carbon for example, is not economically viable since aluminium oxide has a melting point of about 2000 °C. Therefore, it is extracted by electrolysis — the aluminium oxide is dissolved in molten cryolite and then reduced to the pure metal. By this process, the actual operational temperature of the reduction cells is around 950 to 980 °C. Cryolite was originally found as a mineral on Greenland, but has been replaced by a synthetic cryolite. Cryolite is a mixture of aluminium, sodium, and calcium fluorides: (Na3AlF6). The aluminium oxide (a white powder) is obtained by refining bauxite, which is red since it contains 30 to 40% iron oxide. This is done using the so-called Bayer process. Previously, the Deville process was the predominant refining technology. The electrolytic process replaced the W?hler process, which involved the reduction of anhydrous aluminium chloride with potassium. Both of the electrodes used in the electrolysis of aluminium oxide are carbon. Once the ore is in the molten state, its ions are free to move around. The reaction at the negative cathode is Al3+ + 3 e- → Al Here the aluminium ion is being reduced (electrons are added). The aluminium metal then sinks to the bottom and is tapped off. At the positive electrode (anode) oxygen gas is formed: 2 O2- → O2 + 4 e- This carbon anode is then oxidised by the oxygen. The anodes in a reduction must therefore be replaced regularly, since they are consumed in the process: O2 + C → CO2 So, as you can see, the exact tonnage required to produce 1 ton of aluminum is very sketchy at best...
- Q: Are there any health risks associated with using aluminum sheets?
- Yes, there are potential health risks associated with using aluminum sheets. Aluminum is a neurotoxic metal that can accumulate in the body over time. Prolonged exposure to high levels of aluminum has been linked to several health issues, including respiratory problems, bone disorders, and neurodegenerative diseases such as Alzheimer's. Additionally, certain studies suggest a possible link between aluminum exposure and an increased risk of developing breast cancer. It is important to take precautions when working with aluminum sheets and minimize exposure to the metal.
- Q: When zinc dust and sulfur dust are combined in certain proportional ratios and ignited, a violent exothermic reaction occurs. Because the reaction only depends on two components; zinc and sulfur, but not oxygen, the reaction has all of the components that it needs within the mixture. The same is also true for a mixture of magnesium and sulfur.However, the same reaction does not occur with iron and sulfur. Instead, the mixture reacts slowly over a period of a few minutes rather than flashing to smoke in less than a second. Now for my questions:1: If aluminum and sulfur were combined in the same proportional ratios as the zinc and the magnesium mixtures were, would the reaction be as fast as the zinc and the magnesium mixtures? Why or why not?2: What properties of the different metals used in these mixtures makes them behave so differently?
- 1. This depends on the aluminium particle size and it's quality as Al is normally coated with an oxide layer that protects the Al metal underneath. Assuming that the Al powder was good stuff, it should react as violently as the Zn and Mg mixtures. Why .. because it is a very reactive metal ... see further info below. However I needed tried it. 2. The difference is really about the reactivity. Iron, although a reactive metal, is far less reactive than Mg,Al, and Zn. I have tried the zinc and sulphur a number of times and it is really quite violent. With a fair quantityof reactants in the lab it produced an excellent mushroom smoke cloud. I've also seen the Al reactivity demonstrated by a mad Chemistry prof from Nottingham University. He mixed Al powder into a paste with liquid oxygen and ignited it! Wow ... what a reaction.I shall never forget it although it was about 35 years ago!
- Q: just bought a hobart handler 140 (already love it), and was just wondering on what gas to use for aluminum. my welder will be set up for mild steel (75% argon 25% CO2). it would be nice to be able to use this mix with aluminum as well, as it would be easy to just switch spools of wire, but the manual says to use a 100% argon mix when welding with aluminum. will the 25% CO2 make a difference welding aluminum?
- You MUST use 100% Ar for MIG welding aluminum. Molten Al is highly reactive. Al powder is the active ingredient in thermite, for example. It will react with CO2, stripping away the oxygen and creating a nasty mess. Also, you really need a MIG welder with twice as much current output. along the lines of 200-300 amps. 130 amps will not perform well even with a spool gun, and running the weak, prone-to-jamming .030 Al wire. You could try to do it that way, but I would not advise. (There is no way in hell you'd be able to cram wimpy .030 Al wire through a 6 foot traditional welding lead. It'll kink and jam after 5 seconds.) MIG welding aluminum REQUIRES using the high-current, high feed speed, spray transfer mode. Here are some typical parameters: 030 wire, 500 IPM, 22 volts. 120-130 amps. 035 wire, 500 IPM, 23 volts, 150 amps. 045 wire, 400 IPM, 24 volts, 200 amps. EDIT, the guy above me has the right idea. They use electricity to force the reaction between aluminum oxide (dissolved in cryolite) and carbon, producing molten Al and CO2 gas. Normally the reaction would tend to go the other way. Aluminum has a higher affinity for oxygen.
- Q: How thick are aluminum sheets commonly available?
- Aluminum sheets commonly come in various thicknesses, depending on the intended use and application. The most commonly available aluminum sheet thicknesses range from 0.025 inches (0.63 mm) to 0.125 inches (3.18 mm). However, thinner and thicker aluminum sheets are also available, with some going as thin as 0.016 inches (0.4 mm) and others as thick as 0.25 inches (6.35 mm) or more. The specific thickness required will depend on the specific project or industry application.
- Q: What are the common thicknesses of aluminum sheets used in aerospace applications?
- The common thicknesses of aluminum sheets used in aerospace applications range from 0.5 mm to 6 mm, depending on the specific requirements and structural needs of the aircraft or spacecraft.
- Q: How do I cut aluminum sheets?
- To cut aluminum sheets, you will need a few tools and precautions. Here's a step-by-step guide to help you through the process: 1. Safety first: Always wear protective gear, including safety glasses, gloves, and a dust mask to protect yourself from the metal shavings. 2. Choose the right tool: There are a few options for cutting aluminum sheets, depending on their thickness. For thin sheets (up to 1/8 inch), a manual hand shear or a utility knife with a sharp blade can be sufficient. For thicker sheets, you may need power tools such as a jigsaw, circular saw, or a specialized aluminum-cutting saw. 3. Measure and mark: Use a measuring tape, ruler, or a straightedge to determine the desired size of the sheet. Mark the cutting line on the sheet using a permanent marker or a scribe. 4. Secure the sheet: Use clamps to secure the aluminum sheet firmly to a workbench or a cutting surface. This will prevent the sheet from moving during the cutting process, ensuring accurate cuts. 5. Cutting with a hand shear or utility knife: For thin sheets, start by aligning the cutting edge of the shear or utility knife with the marked line. Apply firm and even pressure to make a straight cut. If using a utility knife, you may need to score the sheet several times before it breaks off. 6. Cutting with power tools: If using a jigsaw, circular saw, or an aluminum-cutting saw, make sure you have the appropriate blade for cutting metal. Set the saw's cutting depth slightly deeper than the thickness of the aluminum sheet. Align the blade with the marked line and slowly guide the saw along the cutting path, ensuring a smooth and steady motion. Apply light pressure and let the saw do the work. 7. Finishing touches: Once the cut is complete, inspect the edge for any burrs or roughness. Use a metal file or sandpaper to smooth out any imperfections. Remember, practice caution and take your time when cutting aluminum sheets. It's always a good idea to test your cutting method on a small scrap piece before proceeding with the actual sheet.
