Q:Aluminum Oars Any Good?
Aluminium will make o.k. paddles, but as oars won't be as good as wood. Wood flexes and works differently, unless the aluminium oars have weight in the handles they will not near balance. Cheap wood oars aren't balanced well either, and this is a significant fault. Unless you have used good oars you won't know the difference, but it is very real. Don't like them myself, if money is the issue they will work over short distances, but thats all. Connections and seams tend to corrode over time and let you down with no warning right when you need them - those things clipped on inflatables are a good example of that...
Q:How do I remove aluminum powder that is dissolved in water?
Aluminum does not dissolve in water. In the presence of oxygen (and water), it becomes Aluminum Hydroxide which is worthless pyrotechnically. To boil the water off without heat, use a vacuum pump. You may be involving yourself in a very dangerous enterprise, especially since you don't seem to know anything about chemistry. If you are experimenting, I would keep the quantities very low, a gram or so.
Q:When you open an aluminum beverage can, do particles of aluminum get into the drink?
It depends on the type of drink inside the can. Aluminium is a metal in the group three of the periodic table of elements so it has three positive charges when ionized although it has metallic bond between its nucleus and its electrons. If the drink contains too much acid such as HCl with a high concentration the acid may react with the aluminium can if it is not coated or galvanized. Although it may not physically break off for the particles to enter the drink, it may dissolute in the kind of substance inside the drink.
Q:There is no professional aluminum roll,
Baidu, Inc., a China military there, here not to send.
Q:how to weld aluminum with fluxcore?
You can't. you need a TIG welder to weld aluminum. It's an especially hot welder for aluminum specifically.
Q:Four roller rolling mill roller bearing on the aluminum top how always have holes
Well, typical aluminum plate surface defects in the backup roll print, solution, change support roll.Do not know your factory function division, should have special polishing work roll, support roller grinding workshop, this problem should be addressed to them, sticks are not qualified, how can dry out qualified products?
Q:3 main ideas using the idea that a chemical reaction occurred with a aluminum and copper chloride lab?
Aluminum metal usually has a passivating layer of Al2O3 which prevents aluminum from reacting with Cu2+ ions. Al won't react with CuSO4(aq), for instance. But if NaCl is added then it will. It is the effect of the chloride ion that makes the reaction go. Al2O3(s) + 8Cl-(aq) + 3H2O -- 2[AlCl4]^- + 6OH- Once the passivating layer is dissolved, then aluminum metal is available to react with chloride ion. You see the aluminum metal disappear, while dark red Cu metal is formed, along with the decrease in the blue color due to hydrated copper ions, [Cu(H2O)6]^2+. In addition, aluminum metal has a side-reaction with water to form hydrogen gas. Therefore, you will observe that as gas is given off. Not only that, the temperature of the solution will increase. 2Al(s) + 2OH- + 6H2O -- 2[Al(OH)4]- + 3H2(g) In summary. There are four indicators of a chemical reaction. 1. The formation of a precipitate 2. The evolution of a gas 3. A color change 4. A temperature change. All four indicators are observed. Solid Cu metal is formed. Hydrogen gas is given off. The color of the solution changes from blue to colorless, and the temperature increases.
Q:Impact strength of aluminium 2024 composite after cryogenic?
Aluminum 2024 doesn't have a transition temperature, it absorbs about 18n-m impact strength (via charpy tests I ran three weeks ago at my College course). This was constant between -150ºC to +150°C (liquid nitrogen to a furnace). This excerpt from wiki: Cutting tools In 1982 at the Oak Ridge National Laboratories, George Wei, Terry Tiegs, and Paul Becher discovered a composite of aluminium oxide and silicon carbide whiskers. This material proved to be exceptionally strong. Development of this laboratory-produced composite to a commercial product took only three years. In 1985, the first commercial cutting tools made from this alumina and silicon carbide whisker-reinforced composite were introduced by the Advanced Composite Materials Corporation (ACMC) and Greenleaf Corporation. Leads me to believe it depends on how you mix the material in would make a difference. Silicon Carbide and aluminum make very strong tools, but would make it more brittle. The ceramic in a metallic crystal lattice (metal is a crystalline structure) would allow more voids to coalesce leading to a brittle fracture, but the initial strength would be improved because of substitution dislocations in the crystal structure (it would be more rigid, stronger, but more prone to sudden failure). Silicon carbide has low thermal expansion coefficient compared to aluminum also so when it gets really cold the aluminum would contract around the particles increasing the strength, but again, reducing ductility and causing fractures to occur more rapidly. Anyways, very interesting, you should do a bit of research on your own after this as I gave you some good places to work from (and I'm sure plenty of words to look up ;D )
Q:Aluminium and copper advantages and disadvantages in electrical wires?
Copper does conduct slightly better than aluminum, but aluminum corrodes over time and the oxidized surface has very high resistance. Copper also oxidizes but is not as high a resistance. The high resistance, when in contact with another conductor, like a junction inside a box, will create heat. Those high resistance junctions create so much heat that over time a fire hazard develops. Hence, National Electrical Code disallowed the use of aluminum for safety reasons.
Q:What is the concentration of Aluminum in the Universe?
Interesting, the aluminum must flow? Aluminum is not as common as other elements. It is not readily produced in the cores of stars through the alpha-capture process (which produces things like carbon, oxygen, neon, magnesium, silicon, etc.). This means it is only produced via supernova explosions. The table in Wikipedia (see link below) will give you an idea of the relative abundance to other elements. (Notice that magnesium and silicon, which are before and after aluminum, are nearly 100 times more abundant). As a fellow, Sci-Fi enthusiast, I'd remind you to make you're story believable. If you decide that your universe won't have supernovae, remember that would mean there would be no iron, gold, uranium, etc. My answer has been long enough, but I'm sure you have an idea why aluminum is so abundant on the Earth's crust so I'll stop here.
