What Are Uses of 1070 And 1100 Aluminum Foil

1070 and 1100 aluminum foil are widely used in the electrolytic capacitors, heat exchangers, lithium batteries, transformer, flexible packaging, bottle cap materials. What are their advantages? Learn more.
In the aluminum industry, thicknesses below 0.2mm are usually called aluminum foil. Common aluminum foils include electronic aluminum foil, tape foil, pharmaceutical packaging foil, food packaging foil, etc. Aluminum foils that appear to be the same have very different physical properties and different uses. For example, 1100, 3003 and 1070 aluminum foil are common electronic aluminum foils, that is, aluminum foil for the cathode of electrolytic capacitors.
Lithium batteries are composed of a positive current collector (current collector electrode), a box, a sealing plate, a negative plate, etc. The positive electrode is composed of positive electrode current collector, high-temperature tape, positive electrode matrix and positive electrode material. The chosen material is 1070, 1060, 1235, 1230, 1100, 8011, 1N30, 3003, etc., with a thickness of 0.1 mm. The most commonly used alloys are 1235, 1070, 1100, and 3003 alloys because of their high strength.
The main alloy grades of aluminum foil for heat exchangers are 1100, 1200, 8011, etc. From a usage perspective, air conditioners do not have strict requirements on the chemical composition of aluminum heat exchange fins. Without surface treatment, 3A21 aluminum alloy has relatively good corrosion resistance, high mechanical properties such as strength and elongation, and high hardness. The choice of alloy depends primarily on the final mechanical properties the material can achieve and the ease of the manufacturing process.
The aluminum foil for transformer generally uses 1060, 1070 and 3003 aluminum foils. 1000 and 3000 series aluminum foils are ordinary aluminum plates, and the thickness of aluminum foil used for distribution transformers is generally between 0.02-0.055mm. Because the product production process is relatively simple and the technology is relatively mature, it has a price advantage over 5xxx and 6xxx aluminum alloys.
The raw materials of aluminum foil for aluminum foil bags are mainly 1 series, 3 series and 8 series products, mainly including 1060,1100, 3003, 8011, 8021, etc. The softness and hardness of the alloy, that is, the alloy state, is selected according to the needs of the packaged products. The three commonly used states are H14, H16 and H18.
Aluminum foil for bottle cap is mainly 1050, 1060, 1070 and 1100 aluminum foil. 1xxx aluminum foil is pure aluminum foil. Among all series, 1000 aluminum foil as the most aluminum content, and its purity is above 99.0%. However, for some aluminum bottle caps with special requirements, the performance of the 1000 aluminum alloys may not meet the standards.
