2.Description


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:Which kind of glue is best for bonding aluminum sheets?
502 or universal glue
Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
Q:How to distinguish aluminum sheet from magnesium sheet?
put them into acid and observe bubble's generating speed, the quicker one is magnesium sheet.
Q:Could ring-pull can be transformed as aluminum sheet?
Ring-pull cans will be reused after recycle, there are parts of ring-pull cans be transformed as aluminum sheet.
Q:How to clean the engine oil and kerosene on the surface of aluminum sheet?
you can buy a bottle of petroleum ether in chemical raw material shop, it will be clean after rubbing, or you can buy solvent oil.
Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
general horizontal driving sawing and precision sawing.
Q:is general aluminum sheet fire-proof?
aluminum products has low melting point and is nonfireproof,and aluminum alloys will be better.
Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
