1. Household aluminum foil (container foil---lunch box)
Household foils are widely used in cooking, freezing, preservation, baking and other industries. When preparing food for the refrigerator, you can wrap aluminum foil directly on the food to avoid moisture loss in fish, vegetables, fruits, and dishes, and to prevent flavors from leaking or being mixed in. Because aluminum foil has uniform thermal conductivity, heating, insulation and other effects, it can be used for direct heating in ovens, steamers, flower pots, etc. Commonly used specifications: thickness 0.01---0.2mm, mainly roll-shaped household width 300, 380, 450mm
2. Medicinal aluminum foil
Medicinal foil has the advantages of non-toxic, corrosion-resistant, impermeable, heat-proof, moisture-proof, light-blocking, and high-temperature sterilizability. It is mainly used for the packaging of pharmaceutical capsules, tablets, etc., as well as the bags of powder granules and aqueous agents. Packaging, PTP aluminum foil is moisture-proof, easy to carry, safe and hygienic, and is widely used in the international pharmaceutical industry. Common medicinal foils on the market come in two alloy states. 1235\8079 alloy 0 state, after cold stamping, is used for high-end pharmaceutical packaging; 8011\8021 alloy H18\O state, after coating, is used for ptp medicinal aluminum foil, the common thickness is: 0.007---02mm.
3. Battery foil
Battery foil is one of the base materials of lithium batteries for new energy vehicles. Generally, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode collector. Alloys are usually mainly: 1060\1070\1100\1100B. Commonly used thickness: 0.009-0.1mm.
4. Air conditioning foil
Air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners. The air conditioning foil used in the early days was plain foil. In order to improve the surface properties of the plain foil, an anti-corrosive inorganic coating and a hydrophilic organic coating are applied before forming to form a hydrophilic foil, which is widely used in household industrial air conditioners, refrigeration cabinets, automobile air conditioners and other refrigeration equipment. There is also a hydrophobic foil that makes the surface of the fins hydrophobic to prevent condensation water from adhering. It is mainly used in dryers to improve heating efficiency. Alloy status: 3102/8011, thickness 0.095---0.145mm.
5. Electronic\electrode foil
After the aluminum material is processed into foil, the electronic aluminum foil undergoes surface corrosion treatment and re-oxidation treatment, and then is wound to make a capacitor. The aluminum foil before corrosion is called light foil, the aluminum foil after corrosion is called corrosion foil, and the aluminum foil after re-oxidation is called finished foil. Electronic aluminum foil refers to light foil and is a key raw material for the production of aluminum electrolytic capacitors. The electrode foil includes corrosion foil and chemical foil. Electronic aluminum foil can be divided into high-voltage anode foil, low-voltage anode foil, negative electrode foil, etc. Among them, high- and low-voltage anode foils (formation foils) require more than 99.99% high-purity aluminum. The thickness of high-voltage anode foil is 0.0065-0.11mm, and the thickness of low-voltage anode foil is 0.04~0.1mm
