Product Description:




      AA3***(AA3003 etc)




STANDARD:GB/T 3880-2006

Special specification is available on customer's requirement


Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.

Thin sheets of aluminium are not very effective at attenuating low-frequency magnetic fields. The shielding effectiveness is dependent upon the skin depth. A field traveling through one skin depth will lose about 63 percent of its energy (it is attenuated to 1/e = 1/2.718... of its original energy). Thin shields also have internal reflections that reduce the shielding effectiveness. For effective shielding from a magnetic field, the shield should be several skin depths thick. Aluminium foil is about 1 mil (25 µm); a thickness of 10 mils (250 µm) (ten times thicker) offers less than 1 dB of shielding at 1 kHz, about 8 dB at 10 kHz, and about 25 dB at 100 kHz.

Q:Why is aluminum bad for the body? Why do people say it causes alzheimers?
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
it firstly etches off the oxide on the surface of aluminum, and then reacts with aluminum, generating bubble.
Q:Bohr Model?! Aluminum?
This Site Might Help You. RE: Bohr Model?! Aluminum? For my chem class that I just barely started taking, we're making bohr models. Even though my teacher explained it, I still dont get the concept of it all, like how the protons are lined up in their inner circle and the outer circles. I get everythign else about atoms except how they're...
Q:What glue does stainless steel board and aluminium board glue well?
Stainless steel plate and aluminum plate usually use acrylic structure glue.Acrylic structural adhesive two-component acrylate modified by synthesis and curing agent structural adhesive composition, A, B two agents are 100% solid components; fast curing, high strength, about 5 minutes to 30 minutes after the initial fixation strength up to 80%, 24 hours after the maximum strength; excellent resistance to acid and alkali, water, oil medium, high temperature resistance, better aging properties of metal items between strong adhesion, resistance strength is better than that of epoxy resin, excellent resistance to thermal shock, working at -30~150 DEG C; compliance with international environmental standards, has passed the European ROSH standard.
Q:Analysis of a Magnesium-Aluminum Alloy?
P_H2 = 0.950 atm (Dalton's Law of partial pressures) n=Pv/RT = (0.950 atm)(0.311 L) / (0.08206 (L*atm)/(mol*K))(302.15 K) n_H2 = 0.011915983 mol Balanced equations: Al + 3HCl -- 3/2H2 + AlCl3 Mg + 2HCl -- H2 + MgCl2 By these equations, we know that every mole of Al will give us 1.5 moles of H2, and every mole of Mg will give 1 mole of H2. We can therefore set up an equation for the mass of Al like this: *Let a = the mass of MAGNESIUM* Al = 0.250 g - a With this equation in mind, we can setup two equations solving for 'n' of each element by dividing by its molar mass and multiplying by the molar ratio: n_Mg = a / 24.30 (1:1 ratio, so we don't have to multiply) -- number of moles of H2 produced by the reaction of Mg (now written as n_H') = a / 24.30 n_Al = (0.250 g - a) / (26.98 g/mol) Because of the molar ratio shown above, we must multiply n_Al by 1.5 in order to get n_H2 produced by the reaction of aluminum, hereafter known as n_H2 Since we know the number of moles produced by the sum of the reactions, we can add these equations together and solve for n_H2. (**note that your value will be different because you have a different volume**) Set up the equation like this: n_H2' + n_H2 = n_H2 = 0.011915983 mol Sub in your individual equations for n_H2' and n_H2: (a/24.3) + 1.5[(0.250-a)/26.98] = 0.011915983 mol Rearrange and solve for a (mass of MAGNESIUM): (26.98a + 9.1125 - 36.45a) / (24.3)(26.98) = 0.011915983 0.011915983 = 9.47a a = 0.137298281 g Once you have your 'a' value, divide it by the total mass (0.250 g) and multiply by 100%. This gives you the percentage of Mg. (0.137298281 g / 0.250 g) * 100% = 54.9193 % Since you want ALUMINUM, you must subtract the percentage of Mg from 100. 100 - 54.9193 = 45.08% So, the mass percentage of aluminum is 45.08%. I hope this is helpful!
Q:Aluminium or hi-ten bike?
hi ten is always cheap heavy junk on the other hand aluminum can be pretty crappy too if it costs under $300 don;t expect miracles either way but i would still say aluminum wle
Q:How to sand a aluminum bicycle?
Home or do-it-yourself spray jobs most of the time come out looking like - fill in word of your choice. Why? Because the person hasn't done their homework in advance. First, you will need to strip the bike down to the bare frame - remove everything. Are you qualified to do all of this? Do you have all the tools needed? The next best step would be to have the frame professionally sand blasted, powder-coated clear coated by possibly an auto body shop that does this kind of thing on the side. Can't do that? Consult Google link below. So much FREE information on the Internet, it's amazing.
Q:why can't aluminum sheet burn after polishing?
because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
Q:when touching a piece of aluminum, does the aluminum gain a positive or negative charge?
Aluminum is a metal and a good conductor of electricity. If you touch it, it will get grounded, so it will be neutral. You cannot charge a metal up by touching it with your hand unless you are not grounded yourself. If you are standing on a piece of plastic, say, then it will take whatever charge is on you. If you are positive, it will become positive. If you are negative, it will become negative. But you must be insulated from ground to do that. If you are touching the ground then any charge on the aluminum will just flow out of the metal through you to ground and the aluminum will stay neutral
Q:Which kind of glue can bond two pieces of aluminum sheets?
You can use AB glue.
