Product Description:

1.Structure of Aluminium Coils with Mill Finished for Cold Rolling

Aluminium Coils with Mill Finished for Cold Rolling can be rolled down to aluminium coil,sheet,circle ect.  The alloy AA1050 is widly used in building, industry ect. Its weight is much lower than steel. So many customers choosed aluminium material instead of steel.

2. Main features of Aluminium Coils with Mill Finished for Cold Rolling 

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:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid, generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant phenomena.
Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding is a welding method that pressing the materials to be welded in an area between two poles and switching on current. the current will go through the contact surface and agjacent area, producing resistance heat effect which will heatthe materials into melting or plastic state and make the materials be welded together.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
aluminum will react with oxygen, generating dense Al2O3 oxide film on the surface, once the pure aluminum is exposed in air, it will react with air, generating oxide film to protect it.
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:is aluminum foil spacer poisonous after heating?
It’s a kind of thermoprint material made by pressing the aluminum into sheet, and owing to its similar thermoprint effect to silver foil, so it’s called fake silver foil. Aluminum has soft texture, good ductility, and is silver white, if we use sodium silicate to paste the sheet after pressing on the offset paper, making aluminum foil, the foil can be printed. But aluminum foil is easy to be oxidized and darkens, rubbing and touching will make it darken, so it doesn’t suit for the thermoprint of books’ cover that needs to be preserved for a long time.
Q:which kind of enterprises are aluminium sheet circles used in?
user use cold squezz method to transform the aluminum sheet circle into various standard capacitor shell, aluminium collapsible tube shell, which are broadly used in electron industry, daily chemical industry, medicine, education and automobile products,electrical appliance, heat preservation, machine manufacturing, automobile,spaceflight,military industry,mould, construction, printing and other industries.
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.
