Q:Can aluminum foil coil be stores for a long time?
It is ok within one or two years, but for five or six years, it will be oxidized.
Q:a calculation for aluminium and copper wires?
Copper has lower resistance per unit volume, ie, a 1 cm diameter copper wire has less resistance than a 1 cm aluminum wire. BUT, aluminum is much lighter than Cu for the same diameter. If you used an aluminum wire that weighs the same as the 1 cm diameter copper wire, it would have LOWER resistance. And that is why aluminum is used in power transmission, and also in aircraft, where weight is important. to do this you calculate density resistivity which is (resistivity x density). Here is a partial table: Al 28.2e-9 Ω-m * 2700 kg/m³ = 76e-6 Ω-kg/m² Cu 17.2e-9 Ω-m * 8960 kg/m³ = 154e-6 Ω-kg/m² Ag 15.9e-9 Ω-m * 10500 kg/m³ = 167e-6 Ω-kg/m² Au 22.14e-9 Ω-m * 19300 kg/m³ = 427e-6 Ω-kg/m² Zn 68e-9 Ω-m * 7130 kg/m³ = 485-6 Ω-kg/m² Fe 100e-9 Ω-m * 7870 kg/m³ = 787e-6 Ω-kg/m² Note that Al is half that of Cu.
Q:A Good/Funny Slogan For Aluminum?
Aluminum: Keeping stoners amazed for over 50 years!
Q:Why aluminium plate warp after sandblasting?
It warps because the blasting is relieving stresses in the material. If you stress relieve the material first, it's a heat treating process, then flatten it with a press brake and it will stay flat during sand blast. You might try using aluminum tooling plate, and a chemical etch if your coating needs it to adhere.
Q:recycling aluminum cans?
The dirt won't be a problem, normally. The pebbles might, but I haven't heard any mention of this being a problem. Add: Aluminum melts at around 960 F, while most rocks won't. By that time, the dried up sugars and cigarette butts will have all burned off. You can melt aluminum in a cast iron frying pan, but I really don't recommend trying that: If a drop of water hits the molten aluminum it'll expand somewhere around 1700 times it's original volume, nearly instantly. This will be like a small bomb going off, and molten aluminum will spray all over. That's quite dangerous, even if you do have protective gear.
Q:aluminum can recycling?
They are worth about $0.01 per can. You can take them to any scrap metal yard.
Q:Why the aluminum sheet crack after?
What I want to add is to choose such welding wires as 5383 or 5183 wire whose magnesium content is higher than 5754 wire. The loss of magnesium due to high temperature in welding process may reduce the intensity of welding area.
Q:Can the 5-10cm thick paper sleeve inside the scrapped aluminum coil be sliced? Now we use knife which is much troublesome.
You can use Long Men Rolling Mill to slice directly.
Q:Chemistry Question: Aluminum Production?
Bauxite is dissolved in NaOH to remove impurities and form aluminum hydroxide; the aluminum hydroxide is then precipitated out, and water is removed to produce pure aluminum oxide (alumina). In aluminum production, alumina (Al2O3) is dissolved in molten cryolite (Na3AlF6). This molten mixture is then placed in a container with graphite electrodes (cathode and anode are both graphite). The molten mixture serves as the electrolyte. At the cathode: Al3+ (l) + 3e- ---- Al (l) Aluminum ions gather electrons to form aluminum metal, which is liquid due to the high temperatures. The molten metal sinks to the bottom of the container, and is piped off. At the anode: 2O2- (l) --- O2 (g) + 4e- The oxide ions from alumina lose their electrons to form oxygen gas.
Q:effects of ferrous sulphate on aluminium?
aluminum reacts via a redox reaction with iron(II): 3 Fe2+(aq) + 2 Al(s) --- 3 Fe(s) + 2 Al3+(aq)
