8079 Aluminum Foil Manufacturing Process

The manufacturing process of 8079 aluminum foil involves several steps, including casting, cold rolling, annealing, final cold rolling, slitting and inspection.

Casting and Rolling: Molten aluminum is cast into large plates and then rolled into thin sheets.

Cold rolling: The sheet is passed through a series of rolling mills that reduce the thickness of the foil to the desired level.

Annealing: The foil is heated to a specific temperature and held for a specific time to relieve internal stress and increase its ductility.

Final Cold Rolling: The annealed foil passes through a series of rolling mills to achieve the desired thickness and surface finish.

Cutting and inspection: Cut the aluminum foil into narrow rolls of the required width and inspect them for quality defects such as pinholes, scratches, and wrinkles.

Quality Control: Yongsheng Factory always adheres to quality control in the manufacturing process of all aluminum products, including chemical composition analysis, thickness measurement, surface inspection, pinhole detection, conductivity measurement and tensile strength testing. These tests are performed at various stages of the manufacturing process to ensure that the final product meets the required standards.

Advantages Of Yongsheng 8079 Aluminum Foil:

8079 aluminum foil is an aluminum foil with high strength, good elongation and compressibility. It not only has the advantages of moisture-proof, air-tight, shading, abrasion-resistant, fragrant, non-toxic and tasteless, but also because of its elegant silver-white luster, it is easy to process beautiful patterns and patterns of various colors, so it is easier to process. favored by people. 8079 aluminum foil is widely used in food packaging, pharmaceutical packaging, battery soft packs and other fields

The 8079 aluminum foil produced by Yongsheng has many advantages such as food grade, clean oil removal, less pinholes, good shape, and no deformation when cutting.
1. After being tested by bacteria and mold, it is non-toxic, tasteless, safe and healthy;
2. 8079 aluminum foil has high moisture resistance, air permeability and odor resistance, which can protect the packaging most effectively;
3. The shape is stable at high and low temperatures, and the temperature does not expand, shrink or deform at -73~371°C;
4. Excellent electrical conductivity and shading properties.

8079 Aluminum Foil Applications

Packaging applications: 8079 aluminium foil is widely used in the packaging industry, especially for food packaging such as wrapping and covering dishes, lining baking trays and preserving freshness, and also as a barrier layer in flexible packaging materials such as chocolate bars, confectionery, snacks, yoghurt lids, and pharmaceutical blister packs, among other packaging applications.

Industrial applications: 8079 aluminum foil is used as a heat-sealing material for caps and caps in the cosmetic, drinks and pharmaceutical industries (8079-H18 aluminum foil and 8011 aluminium foil are most suitable for pharmaceutical packaging). In addition, it is also heat-insulating, light-proof, and air-proof, and is also used as an ideal barrier material for other industries.

Electrical application: Soft-pack batteries are usually packaged in aluminum-plastic film, which is an aluminum foil composite material. The aluminum foil layer adopts 8021 aluminum foil and 8079 aluminum foil, which are the key materials for flexible packaging lithium battery cell packaging, and they are the most commonly used raw materials for sealing and protecting single-chip lithium batteries. The common specifications of aluminum foil for battery soft packs are 0.035-0.055mm, and 8079 aluminum foil is used in the manufacture of electronic products such as capacitors, lithium-ion batteries and other electronic components. Due to its high thermal conductivity, it is occasionally used in heat exchangers, air conditioning units, freezers, and other cooling equipment.

Why Is 8079 Aluminum Foil Popular In The Lithium Battery Industry?

8079 aluminum foil has good electrical properties. Electrolyte is needed to transfer charge inside the battery. 8079 aluminum foil has high conductivity and can effectively transfer charge to ensure the normal operation of the battery. 8079 aluminum foil has good corrosion resistance and can effectively resist electrolyte corrosion. Aluminum foil material itself has good processability and plasticity, and can meet the processing and forming requirements of battery packaging. More importantly, the production cost of aluminum foil packaging is low, and it can also suppress battery polarization, reduce thermal effects and significantly improve the consistency of battery pack use.

8079 Aluminum Foil Vs 8021 Aluminum Foil

8021 aluminum foil and 8079 aluminum foil are common aluminum foil materials, and their chemical compositions are slightly different. The alloy components of 8021 aluminum foil are silicon, iron, manganese, copper and other elements. 8079 aluminum foil contains manganese, magnesium, chromium, etc. Secondly, the uses of 8021 aluminum foil and 8079 aluminum foil are also different. 8021 aluminum foil is usually used to make pharmaceutical packaging, food packaging, tobacco packaging, etc. because it has good moisture-proof, anti-oxidation, anti-ultraviolet and other properties. 8079 aluminum foil is usually used to make the packaging of electronic products such as capacitors and batteries because it has good electrical properties and corrosion resistance. The surface of 8021 aluminum foil is smoother than 8079 aluminum foil, while the surface of 8079 aluminum foil is rougher. The strength and toughness are also higher than 8079 aluminum foil, but the ductility of 8079 aluminum foil is better than that of 8021 aluminum foil.
