Product Description:

Aluminium is a relatively soft,durable, lightweight, ductile and malleablemetal with appearance ranging from silvery to dull gray,depending on the surface roughness. It is nonmagnetic and does not easilyignite. A fresh film of aluminium serves as a good reflector (approximately92%) of visible light and an excellent reflector (as much as98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the density and stiffnessof steel. It iseasily machined,cast, drawn and extruded.

Application: Foil stock, Circles, Roofing, Canstock, Marine plateAnti-sliperypurpose in vehicles, packing and appliance.

According to the order of the thermal conductivity of the metal, corrosion resistance and production cost, refrigerator interior sheet metal is chosen instead of aluminum other metals, to ensure its good thermal conductivity of the premise, as far as possible to reduce costs and the choice of corrosion-resistant material processing, aluminum is the best choice.
Secondly, in order to increase the length of the liner internal exchange area and the outside air heat, refrigerator interior selected embossing plate instead of the flat plate. In the absence of refrigerator interior space cause pressure to increase the use of embossed aluminum air tank wall contact area for a more efficient uniform heat exchange.

Speaking on the cooling rate: according to the laws of physics, thermal conductivity of aluminum is 237W / mK, the thermal conductivity of iron is 80W / mK, the thermal conductivity of the larger the number, the better the thermal conductivity, under the same conditions cooling faster the cooling effect is better. Using embossed aluminum evaporator, cooling rate is 3 times the wire tube evaporator. You can do a little to test in the refrigerator freezer compartment through an aluminum plate on a drop of water drops, 5 seconds into the ice, cooling is very fast!

Q:is there aluminum oxide on the surface of aluminum sheet after being polished by abrasive paper?
aluminum will be oxided as aluminum oxide once being exposed in air.
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
Because there is oxide on the surface of aluminum, the reaction will be quicker after polishing the oxide with abrasive paper.
Q:what will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
Q:does aluminum sheet has a function of magnetism isolating?
yes.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
it does within the range of magnetic force.
Q:is general aluminum sheet fire-proof?
general aluminum sheet is less fireproof than tinfoil.
Q:what's the oxidation method of positive pole on the surface of aluminum sheet?
Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
Q:how to find 0.6mm waste strake of aluminum sheet?
ask door and window maker for some strake.
Q:How to distinguish aluminum sheet from magnesium sheet?
put two sheets into excess NaOH. The one that reacts with NaOH, generating sediment, is magnesium sheet,(sediment, but Al(OH)3 is amphoteric:Mg(OH)2) another one without sediment is aluminum sheet(in fact, there is sediment Al(OH)3, but it will react with alkali,)
