Aluminum Foil Applications
Packaging aluminum foil: Aluminum foil has outstanding properties of impermeability (especially for oxygen and water vapor) and light-shielding properties. It also has the characteristics of shape retention and rigidity. Packaging food with aluminum foil can prevent air from entering the food packaging bag.
Air conditioning Aluminum foil: Aluminum is widely used due to its advantages of low density, good thermal conductivity, easy processing, odorless, environmental protection and low price. The use of aluminum foil to make thermal conductive fins for air conditioning heat exchangers is one of the representatives.
Electronic aluminum foil: refers to the light foil, which is the key raw material for the production of aluminum electrolytic capacitors. Due to the sequence of the production process, it is divided into electronic aluminum foil and electrode foil.
The electrode foil includes corrosion foil and chemical foil.
Capacitor foil is a corrosive material that works under polar conditions, and has high requirements on the structure of the foil. There are three types of aluminum foils used: cathode foil with a thickness of 0.015-0.06mm, high-voltage anode foil with a thickness of 0.065-0.1mm, low voltage anode foil with a thickness of 0.06-0.1mm. The anode foil is made of industrial high-purity aluminum, and the mass fraction should be greater than or equal to 99.93%, while the purity of aluminum used for high-voltage anodes should be greater than or equal to 4N.
Battery Aluminum Foil: this kind of aluminum foil is used as a current collector for Li-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the positive current collector. Rolled foil thicknesses vary from 10 to 50 microns. The pure aluminum foil commonly used for lithium battery has various alloy grades such as 1060, 1050, 1145, 1235 and has states such as -O, H14, -H24, -H22, -H18.
Common Aluminum Foil Alloy Grades
1050/1060 Aluminum Foil
Mainly used in food packaging, cable tapes, capacitors, etc.
1235 Aluminum Foil
Aluminum Alloy 1235 has mature production technology, stable quality, and excellent mechanical properties such as elongation and tensile strength. It is mainly used in household foils, container foils, medicine foils, soft packs, heat sealing, beer standard single and double zero foil blank, cable tape blanks, bottle caps, aluminum-plastic panels, curtain wall panels, etc.
3003/3004 Aluminum Foil
3003 3004 aluminum alloy is the most widely used anti-rust aluminum, with moderate strength, good corrosion resistance, good weldability, and excellent product characteristics such as ductility changes with cold processing and heat treatment. They have been mainly used in container lunch boxes, food packaging foils, electronic foils as well as roofing color coatings, deep-drawing wafers, glass spacers, curtain wall panels, battery shells, high-frequency welded pipe materials, etc.
3004 aluminum foil is a kind of Al-Mn alloy, adding the strengthening element magnesium. It has the advantages of 3003 alloy, and at the same time has higher strength than 3003 alloy, and has good formability, solubility and corrosion resistance.
5052 Aluminum Foil
5052 aluminum foil belongs to Al-Mg alloy, which is widely used and is a promising aluminum alloy. It has the advantage of high strength, especially high fatigue strength, high plastic rust and corrosion resistance, good weldability, poor machinability, and polishability. 5052 aluminum foil is mainly used in container lunch boxes, cans, umbrella frames, trolley cases, door handles, high-end signs, etc.
8006/8011 Aluminum Foil
8006 8011 alloy aluminum foil products have the characteristics of high strength, excellent elongation and rolling performance. The product is smooth, flat, not easy to deform and has extremely high moisture resistance, fresh-keeping performance. It is the quality materials used for making lunch boxes, egg tart trays, etc. 8006 8011 aluminum foil is mainly used in household foil, container foil, medicine foil, food packaging, etc.
8079 Aluminum Foil
8079 alloy aluminum foil products have the characteristics of high strength, excellent elongation and rolling performance, high moisture resistance, fresh-keeping performance, and not easy to deform. 8079 aluminum foil is mainly used in medicine foil, food packaging, household foil, container foil, etc.
