Countries in the world have different regulations on the maximum thickness of aluminum foil, such as 0.15mm(5.91 mils) in the United States, 0.20mm(7.87 mils) in Japan, 0.20mm(7.87 mils) in Germany, 0.15mm(5.91 mils) in the United Kingdom, 0.20mm(7.87 mils) in France, 0.05mm(1.97 mils) in Italy, 0.04mm(1.57 mils) in Sweden, and 0.04mm(1.57 mils) in the former Soviet Union. It is 0.20mm(7.87 mils), and in my country is 0.20mm(7.87 mils).
Aluminum foil is generally supplied in rolls, and the diameter of aluminum foil rolls is generally 180-230mm.
Sem stendur, the industrial aluminum foil produced in my country mainly has 4 widths and 18 different thicknesses. The series of products are introduced as follows.
(1) Width range of aluminum foil: 10～39mm, 39～130mm, 130～220mm, 220～600mm, o.s.frv. 4 tegundir. (2) Þykkt álpappírs: 0.005mm(0.20 mils), 0.0075mm(0.30 mils), 0.010mm(0.40 mils), 0.012mm(0.47 mils), 0.014mm(0.55 mils), 0.016mm(0.63 mils), 0.020mm(0.79 mils), 0.025mm(0.98 mils), 0.030mm(1.18 mils), 0.040mm(1.57 mils), 0.050mm(1.97 mils), 0.060mm(2.36 mils), 0.070mm(2.76 mils), 0.080mm(3.15 mils), 0.100mm(3.94 mils) , 0.120mm(4.72 mils), 0.150mm(5.91 mils), 0.200mm(7.87 mils) 18 tegundir.
The thickness of aluminum foil rolls is usually less than 0.2mm. Different thicknesses have different uses. We can customize different thicknesses according to your requirements
Aluminum foil is rolled without rolls, and the rolls are always in a state of elastic flattening.
Meðan á rúlluferlinu stendur, the thickness of the foil can be controlled by adjusting the rolling force, rolling speed and controlling the tension.
In the process of rough rolling, the thickness of the foil is controlled by the rolling force; in the process of finishing rolling, the thickness of the foil decreases with the increase of the rolling speed; The conditional yield strength is σ0.2～0.4
During low-speed rolling, heavy oil or thin oil is often added to the lubricating oil to adjust the rolling thickness of the aluminum foil. Lubricants and roll conditions have a very important influence on foil quality.
