1.Structure of Aluminium Back Coils for Aluminium Composite Panel

Aluminium Back Coils for Aluminium Composite Panel are widly used in decoration field. For the painting, it depends on the using evironment.  If you use in the open air, we recommend the PVDF coated aluminium coils. This kind of painting can last 15-20 years.  If you use in the room, we recommend PE coated aluminium coils. The price is much more competitive.

2. Main features of Aluminium Back Coils for Aluminium Composite Panel

a.Competitive price---We have our own mills and can produce mill finished aluminium coils, so we can control the production cost better.

b.Professional after-sale service---We have more than 15 years exportation experience and you need not worry about the exporation problems.

c.Fast delivery time---We can control the delivery time within 35 days.

Q:Is aluminum a hard metal for a ring?
Aluminum is a quite soft metal, but so is gold. It is true that aluminum is light in weight but magnesium is even lighter and is common enough that a ring could be made of it. Metals can be made harder by adding small amounts of other metals or even by the way it is heat treated. .
Q:how many tons of alumina can yield 1ton of Aluminium?
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of the reduction cells is around 950 to 980 °C. Cryolite was originally found as a mineral on Greenland, but has been replaced by a synthetic cryolite.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 Wöhler 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:did Apple stop selling Mac Aluminum?
Yes...All Aluminium Macbooks are now turned to Macbook Pros. So might want to try the Mid 2009 white macbook or you have to go with 13 Macbook Pro... vist www.parithi.co.cc for details..
Q:25mm thickness of hard aluminum processing to 6mm how to process?
Oh, the 25mm thickness of the hard aluminum processing to 6mm, I suggest you contact the mill for rolling it.
Q:Aluminum vs Carbon road bike frame?
Carbon fiber and aluminum are newer and increasingly popular substitutes for the original bike frame material, steel. In the early 21st century, carbon fiber gained a reputation for being lightweight and the latest frame technology, but advancements in aluminum alloys and frame construction make the two frame materials equal contenders for best material. Almost all carbon fiber bicycles are designed for competitive road riders, who can get increased speed from riding on such a lightweight material. In contrast, aluminum frames are available for road, mountain, cyclocross, hybrid and other models of bikes as they come in different grades. Carbon fiber frames are not always lighter than aluminum frames. Weight depends on construction methods. According to outdoor equipment retailer REI, when it comes to bike frames, the more you pay, the less it weighs, and this holds true for carbon fiber and aluminum bikes. Compare two bikes of any frame material, and the lighter one will cost less. Due to the weight forces operating on a loaded-down touring bike, carbon fiber is a poor choice for such trips, as well as for any sort of off-road riding or trick riding. Lance Armstrong notes that the areas where metal fittings, such as fork ends, bottom bracket shells or headsets, attach to a carbon fiber frame are particularly weak. Carbon fiber is excellent for racing, with its combination of durability and weight. Aluminum frames handle better the weight and shocks of grocery shopping, commuting and trail riding.
Q:why intact aluminum sheet stop quicker than pectinate one in the magnetic field?
while swinging in the magnetic field, intact aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the aluminum sheet stop quickly.but pectinate aluminum sheet can't formulate intact eddy current, so intact aluminum sheet stop quicker than pectinate one.
Q:What is in the aluminum in my 1991 Trek 2300?
You can NOT weld back an aluminum frame unless you have the facilities to anneal and heat treat the frame again. Rewelding without the post treatments will result in a very soft area around the new weld causing sudden catastrophic failure... this means if you are riding it could fail at any time causing injury or death. EDIT: Wait just a durn minute. The 2100 and 2300 had carbon fiber tubes bonded to aluminum lugs and stays. If your bike failed then you ABSOLUTELY should not try to weld it. The heat from welding (even if you had post treatment facilities) would destroy the bond between the CF and aluminum. Fair warning- cut the frame apart and throw it away.
Q:Painting home exterior aluminium siding?
Two good answers above me, but I do want to add that aluminum siding will chalk on the outside. Definetely needs to be power washed, preferably with TSP (Tri Sodium Phosphate). That will get the metal totally clean to give it good tooth for the prime and paint. As said above, you need an aluminum prime, which is not a problem. Any paint store, Home Depot or Loews in the paint department can lead you to the right prime. Just make sure you are using the corresponding paint for your prime. Anyone can slap on a coat of paint, but when you do the groundwork first, you will have a paint job that will look like new for many years. I hope this helps you.
Q:What is the aluminum recycling process?
First, aluminum is shredded. It is then melted and turned into molten aluminum. Once it becomes molten, the used aluminum does not differ from new aluminum. It is then molded into the new product. Recycling aluminum is much more energy efficient than melting new ore into aluminum because it takes three times the energy to produce than if it was recycled.
Q:Aluminium Reactivity?
Aluminum is very reactive so what happens is that it has a coat aluminum oxide as soon as it comes in contact with oxygen the outer layer forms aluminum oxide Al2O3. That is why Aluminum does not rust. The Al203 coat protects it.
