Packaging aluminum foil: Aluminum foil has outstanding impermeability (especially oxygen and water vapor) and light-shielding properties. It also features shape retention and rigidity. Packaging food in aluminum foil can prevent air from entering the food packaging bag.
Air conditioning aluminum foil: Aluminum is widely used due to its low density, good thermal conductivity, easy processing, odorless, environmentally friendly, and low price. The use of aluminum foil to make heat-conducting fins for air-conditioning heat exchangers is one of the representatives.
Electronic aluminum foil: refers to light foil, which is a key raw material for the production of aluminum electrolytic capacitors. Due to different production process sequences, it is divided into electronic aluminum foil and electrode foil.
Electrode foils include etched foils and chemical foils.
Capacitor foil is a corrosive material that operates under polar conditions and places high demands on the structure of the foil. There are three types of aluminum foil used: cathode foil thickness 0.015-0.06mm, high-voltage anode foil thickness 0.065-0.1mm, low-voltage anode foil thickness 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 the aluminum used for high-voltage anodes should be greater than or equal to 4N.
Battery Aluminum Foil: This aluminum foil is used as a current collector for lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the cathode current collector. Rolled foil thickness varies from 10 to 50 microns. Commonly used pure aluminum foils for lithium batteries include 1060, 1050, 1145, 1235 and other alloy grades, and are available in -O, H14, -H24, -H22, -H18 and other states.
