Aluminum foil production: In 2020, China's aluminum production reached 42.1 million tons, aluminum foil strip blank 720,000 tons, aluminum foil production of 4.15 million tons, the finished product rate of 88%. In 2020, there are more than 500 foil strip rolling lines, with a production capacity of more than 5.5 million tons/year. By 2020, China has more than 500 foil strip rolling lines, with a production capacity of over 5.5 million tons/year, and imported 60-70 sets of Aschenbach foil rolling mills from Germany. In 2020, China imported 72,000 tons of aluminum foil, an increase of 4.8% compared with the import volume in 2019. In 2020, China exported 1.233 million tons of aluminum foil, a decrease of 4.8% year-on-year. China's aluminum foil production is expected to reach 4.33 million tons in 2021.
Market share: In 2020, China's packaging aluminum foil production is the most, 2.15 million tons, accounting for 50% of the total production; Followed by air conditioning aluminum foil, 950,000 tons, accounting for 11% of total production; Electronic foil and battery foil combined 170,000 tons, accounting for 4 percent of the total production.
Packaging ALUMINUM FOIL OUTPUT: ALUMINUM foil has IMPERMEability to AIR (especially for oxygen, water vapor) and light shielding performance, but also has the characteristics of CONFORMability and rigidity, using aluminum foil to package food can prevent air from entering the food packaging bag. According to the data, China's packaging aluminum foil production increased from 1.74 million tons in 2016 to 2.15 million tons in 2020, with an average annual compound growth rate of 4.94%; It is estimated that the production of aluminum foil packaging in 2021 can reach 2.2 million tons
Air conditioning aluminum foil output: aluminum is widely used because of its low density, good thermal conductivity, easy processing, tasteless, environmental protection and low price, and other advantages, with aluminum foil to make air conditioning heat exchanger heat conduction fin material is one of the representatives. According to the data, the production of aluminum foil for air conditioning reached 900,000 tons in 2019, and 950,000 tons in 2020, a year-on-year increase of 5%; The production of aluminum foil for air conditioning is expected to reach 1.05 million tons in 2021.
Electronic aluminum foil: refers to light foil, which is the key raw material for the production of aluminum electrolytic capacitors. Due to the order of the production process, it is divided into electronic aluminum foil and electrode foil, among which electrode foil includes corrosion foil and foil formation. Capacitor foil is a corrosive material working under polar conditions, which has high requirements on the foil structure. There are three kinds of aluminum foil used: cathode foil with thickness of 0.015-0.06mm, anode foil with thickness of 0.065-0.1mm and anode foil with thickness of 0.06-0.1mm. The anode foil is industrial high purity aluminum, the mass fraction should be greater than or equal to 99.93%, and the purity of aluminum for high pressure anode should be greater than or equal to 4N. The Chinese standard only stipulates the content of Fe, Si and Cu, but does not specify the content of other elements such as Mg, Zn, Mn, Ni and Ti. The impurity content of foreign battery aluminum foil is obviously lower than that of domestic.
Battery aluminum foil: Used as a collector for lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as a positive collector. The thickness of the rolled foil varies from 10 to 50 microns. Commonly used pure aluminum foil for lithium batteries has 1060, 1050, 1145, 1235 and other alloy brands, including -O, H14, -H24, -H22, -H18 and other states.
