Product Description:

 1.Structure of Cold Rolling Aluminium Coils for Color Prepainting

 

Cold Rolling Aluminium Coils for Color Prepainting is one semi-finished aluminium material. This strip 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 the product

Q:How much will be burned out if the soaked and oxidized 5182 aluminum coil is melt down and reprocessed?
Burn out rate is generally between 1% -2.5%, but that varies among plants as their actual situations are different.
Q:What’s the loss rate per kg when processing aluminum coil to aluminum sheet?
Weight=(0.8×1220×2440×2.7)/1000000=6.4kg
Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:How many 1220mm*2440mm aluminum sheets can one-ton aluminum coil be sliced to? Thank you.
If it is 1.0mm thick, the coil can be sliced into 124 pieces. For other thickness, please use 124 divide the thickness.
Q:How to calculate the wall thickness with the gross weight of aluminum coil known?
Gross weight*density=volume volume÷(aluminum sheet *width)=thickness
Q:What kind of sensor is appropriate for aluminum coil thickness measurement?
You can use laser sensor.
Q:How much is the rust-proof and thermal insulation aluminum coil?
3003 alumal alloy is the best and common rust-proof and thermal insulation aluminum coil. The price depends on the thickness and width you need.
Q:How much cube is the 0.9mm aluminum rolling?
This is a common problem. Anyone who had received high school education can calculate it very quickily. One way is to calculate sectional area with circular area, then times the thickness of the aluminum rolling. Another way is to use the outer diameter circular area to subtract the core area and then times the thickness of aluminum rolling.
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
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.
