Product Description:

1.Description

Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner.

The continuous casting method is much less energy intensive and has become the preferred process.For thicknesses below 0.025 mm (1 mil), two layers are usually put together for the final pass and afterwards separated which produces foil with one bright side and one matte side.The two sides in contact with each other are matte and the exterior sides become bright, this is done to reduce tearing, increase production rates, control thickness, and get around the need for a smaller diameter roller.

5.FAQ:

1)what is aluminum?


Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. 


Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.


2)What's kind of payment term we can supply?


CIF,CFR, FOB and other.


3)Can we supply samples?

Yes, we can!

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:does aluminum sheet has a function of magnetism isolating?
no, it needs ferromagnetic materials.
Q:as for heating coil and aluminum sheet, which one is better for heating?
Heating coil has a short lifetime, and aluminum sheet for heating can be used for a long time. Stainless steel heating tube is embedded into aluminum sheet for heating, because the heating coil isn’t exposed, it can be used for a long time.
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
You can sprinkle the mix of Alkaline water,vinegar,washing powder and liquid detergent on the surface. And after a period of time, rub it with soft silk, after it being dry,sprinkle again and rub until it's clean.
Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
no, but I'm not certain.
Q:who knows the ceiling technology of aluminum sheet?
Construction technology of ceiling aluminum sheet: (1) firstly check keel’s quality, the straight shape and uniformly forced state of boom, control the keel’s gap within 500mm, reduce the gap according to design requirement under humid environment. The lower surface of keel is smooth without a sense of bearing down, main device is closely connected with accessories, it can be bound after being confirmed qualified.(2) we should break the board along the cutting line and ensure the margin of cutting board straight and square without any chipping or arris defect. (3) while placing and fixing the board, we can place edge of aluminum-plastic panel(encapsulated edge) in the vertical direction of supporting keel, there is a phenomena of hanging. Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. You can start from a plate angle or middle position, and don’t place them at the same time. Slab joint should be straight and in the same width, without break joint. (4) in the process of joint, Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. And the butt joint should be stagger, the butt joint can’t be connected on the same keel. When you use doubling plate, the joints of the second layer board and the first layer board can’t be connected with the same keel, double-deck gypsum board should be staggered joints.
Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
It does in theory, but rubber and aluminum sheets can’t be too thick, larger magnetic force of magnet will be better.
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:Which kind of glue is best for bonding wood and aluminum sheet together?
You can use 502 adhesive.
Q:What's the standard thickness of aluminum sheet?
the thickness of tobacco aluminum foil and red wine bottle cap is designed according to customers demands and manufacturer has no stated specification.
