2.Description


 

In Europe aluminium experiences high rates of recycling, ranging from 42% of beverage cans, 85% of 

construction materials and 95% of transport vehicles.Recycled aluminium is known as secondary aluminium, but maintains the same physical properties as primary aluminium. Secondary aluminium is produced in a wide range of formats and is employed in 80% of alloy injections. Another important use is for extrusion.


White dross from primary aluminium production and from secondary recycling operations still contains useful quantities of aluminium that can be extracted industrially.The process produces aluminium billets, together with a highly complex waste material. This waste is difficult to manage. It reacts with water, releasing a mixture of gases (including, among others, hydrogen, acetylene, and ammonia), which spontaneously ignites on contact with air;contact with damp air results in the release of copious quantities of ammonia 

gas. Despite these difficulties, the waste has found use as a filler in asphalt and concrete.

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:Removing electrons from Aluminum?
One approach to this can use the density of aluminum to find the mass of the1 cm³ block. The density of aluminum is 2.70-g/cm³ so your cube has a mas of 2.70-g. The number of aluminum atoms in this block is: 2.7-g Al x (1 mol Al / 27.0-g Al) x (6.023 X 10²³ atoms Al / 1 mol Al) = 6.023 x 10²² atoms Al. Each Al, as you pointed out, contains 13 electrons so we have 6.023 x 10²² atoms Al x 13 electron/atom = 7.83 x 10²³ electrons. 1 x 10¹² pC = 1 C and 1 C = 6.24 x 10¹⁸ electrons=== 1.5 pC x (1C / 1 x 10¹² pC) x ( 6.24 x 10¹⁸ electrons / 1 C) = 9.36 x 10⁶ electrons a.) % removed = 9.36 x 10⁶ / 7.83 x 10²³ x 100% = 1.2 x 10⁻¹⁵ % b.) Each electron has a mass of 9.11 x 10⁻²⁸-g , so the total mass removed =9.11 x 10⁻²⁸-g/elec x 9.36 x 10⁶ electrons = 8.53 x 10⁻¹⁴-g. Thus the % decrease is (8.53 x 10⁻¹⁴-g/ 2.7-g) x 100% = 3.16 x 10⁻¹² %
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
Q:Will an aluminum can rust under water for a period of time?
Aluminum will not rust. Only iron rusts. Because steel has iron in it, steel can rust.
Q:why is copper better than aluminum?
Unless you have a specific purpose in mind, I don't think copper is used as much as aluminum. Aluminum was used in house wiring for a short time because it is less expensive than the usual copper, but something about it caused house fires. (I think it was thermal expansion caused connections in switches to loosen creating connections that would heat up, or spark.) Copper is preferred for house wiring. Copper is about 3 times more dense, so Al is used where light weight is a consideration. I can't remember the last time I drank something out of a copper can.
Q:why is aluminum oxide used more frequently than silicon carbide as an abrasive?
Aluminium Oxide Grinding Wheel
Q:Separating aluminum and copper on a radiator?
i've got in no way heard of the dry ice trick it may be exciting to work out if it certainly worked. i'm sorry to assert except you may isolate the water out of that pipe you will ought to empty the zone.
Q:how do i get read of condensation behind aluminum siding?
Aluminum siding can be vented with round pop-in perforated vent plugs, these are very easy to install. I would really like to know how do you know there is condensation behind your siding?
Q:aluminum can recycling?
Aluminum is not biodegradable. Also making aluminum from ore requires a lot of energy. Recycling cans is easy and saves a whole lot of energy reducing green house gases. Recycling aluminum also reduces the mining required to dig up aluminum ore thereby saving the land and stopping pollution from mine run-off.
Q:Could someone please explain what this means about aluminum cans?
Since aluminum is melted down recycle it is easier to melt down cans as we know.To extract the aluminum from the earth takes more to process there for volume of gas cost more;
