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!


4)What can you do if you have other quastions?

Q:Can the 5-10cm thick paper sleeve inside the scrapped aluminum coil be sliced? Now we use knife which is much troublesome.
You can use Long Men Rolling Mill to slice directly.
Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
It is either the external or the bearing problem in designing and installing.
Q:Will the surface of aluminum contact water if the aluminum coil falls into water?
You mean whether water will penetrate into the gap? If you get it out quickly, basically it will be ok. If there is something wrong, you can put it under the sun to see whether there is water oozing from the gap.
Q:Can aluminum coil 3003H24 replace 3A21H14?
It is ok in some way as both of them are alumal. The hardness of 3003H24 is similar to that of 3A21H14 after hardening without annealing. Both have good corrosion resistance, plasticity and bad machinability. They cannot be used as load bearing parts even though small load is ok. They cannot be anodized.
Q:What do the two items (COIL:873347 HEAT: number) on the label of the raw material of aluminum coil stand for?
COIL means aluminum coil and HEAT means heating, so together they mean hot rolled coil.
Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
Q:Can aluminum foil coil be stores for a long time?
It is ok within one or two years, but for five or six years, it will be oxidized.
Q:Why the aluminum sheet crack after?
It is either because of wrong filling material for welding or bad welding quality. It doesn’t crack after welding, but cracks when the increasing tension in circling process exceeds the internal stress of the weld.
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:What are the production processes of aluminum coil and what are the functions of various industrial furnaces in the production of aluminum? The more detailed, the better. Thank you! Points!
There are aluminum annealing furnace, aluminum alloy quenching furnace, aging furnace and smelting furnace.
