The thickness of aluminum foil coil is usually less than 0.2mm. Different thicknesses have different uses. We can customize different thicknesses according to your requirements.
Aluminum foil can be divided into industrial aluminum foil and packaging aluminum foil. Industrial aluminum foil has a relatively pure chemical composition, with a thickness of 0.005 to 0.2 mm. It is mainly used as capacitors, thermal insulation materials, and moisture-proof materials in the electrical and electronic industries. The thickness of the packaging aluminum foil is generally 0.007 to 0.1 mm. There are various products such as flat foil, printed foil, painted printed foil, and laminated aluminum foil. They are mainly used as packaging materials for food, tea, cigarettes, etc.
The minimum thickness of aluminum foil produced by the tape production method can reach 0.0025 mm and the width can reach 1800 mm. Aluminum foil rolling is roll-free rolling, and the rolls are always in an elastic flattened state. During rolling, the thickness of the foil can be controlled by adjusting the rolling force, rolling speed and controlling the tension. During rough rolling, the rolling force is used to control the thickness of the foil; during finishing rolling, the thickness of the foil decreases as the rolling speed increases; the greater the tension, the smaller the thickness; in order to prevent fragmentation, the tension is usually selected as foil The conditional yield strength of the material is 0.2 to 0.4 of σ0.2.
In low-speed rolling, “thick oil” or “thin oil” is often added to the lubricating oil to adjust the rolling thickness of the aluminum foil. Lubricant and roll status have a very important influence on the quality of the foil. The aluminum foil blank comes from cold-rolled aluminum coils, which are generally pre-annealed at 340-480°C, with a thickness of 0.4-0.7 mm. The pass deformation rate during rolling is about 50%, and the total deformation rate can reach more than 95%. The finished foil with a thickness of less than 0.01-0.02 mm should be rolled and double-sheet rolled.
