Aluminium Foil Thickness Values and Measuring Methods

Aluminium Foil Thickness Values for Different Types of Application:
Aluminum foil for cigarette packing (1235-O, 8079-O): 0.006 ~ 0.007mm
Aluminium foil food packaging (8011-O): 0.008 to 0.02mm
Alu foil for battery(1235-H18, 1060-H18, 1070-H18): 0.012 to 0.035mm
Aluminium foil for pharmaceutics (8011-H18; 8021-O): 0.02 to 0.075mm
Aluminum foil for container (8011-H24,3003-H24,8011-H22): 0.02 to 0.20mm
Alu foil for air conditioner(3102, 8011-H22/H24/H26): 0.08 to 0.2mm
Alu foil for cable wrapping(1235-O): 0.006 to 0.04mm

Aluminium Foil Thickness Measuring Methods
The width and length of aluminium foil is usually measured by a ruler in centimeters. Crumple the piece of foil into a small ball or fold it into a small shape and place it on a milligram balance to find the weight. Records the values on a sheet of paper or data table.
The relationships of different values are:
density = mass ÷ volume
volume = length x width x height.
thickness=mass÷ (length of foil x width of foil x density of aluminum)
The density of aluminum is 2.7 g/cm3. So if you have a piece of aluminum foil of 15 cm long, 20 cm wide and 1.8 g weight, the calculation is 1.8 ÷ (15 x 20 x 2.7)=0.00222 cm.

If you want to convert the thickness into inches, remember that 1 cm is equivalent to 0.39370 inches. In the example above, you would work out 0.00222 x 0.39370, which is 0.000874 inches.

Slitting of 1mm 2mm 4mm aluminium strip

What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate slitting. The loop

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid purposes as tread pla

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking, clients requi
