Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used
broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods,
which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to
preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on
a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in
aluminium foil.
Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the
production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers
with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry
to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the
perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing
out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is
88% while dull embossed foil is about 80%.

Additionally, aluminum coils can be fabricated with specific features such as perforations, embossing, or edge treatments to meet specific functional or aesthetic requirements. With the ability to be customized, aluminum coils offer flexibility and versatility for a wide range of industries and applications.
- Q:Are aluminum coils compatible with different joining methods?
- Different joining methods can be used with aluminum coils. Aluminum, a versatile metal, can be joined using techniques like welding, brazing, soldering, and mechanical fastening. The choice of method depends on the specific application and desired joint properties. To join aluminum coils, welding is commonly used as it creates a strong and durable bond. Various welding techniques, such as MIG, TIG, and resistance welding, can be employed based on the thickness and alloy type. Brazing is another effective method for joining aluminum coils. It involves heating a filler material with a lower melting point than the base metal to create a strong joint. Brazing is suitable when joining aluminum coils with dissimilar metals. For thin aluminum coils or when a lower temperature method is necessary, soldering is a suitable option. It involves melting a low-temperature alloy (solder) to join the coils together. Soldering finds common use in electronics and plumbing applications. Mechanical fastening methods like bolts, screws, rivets, or clips can also be used to join aluminum coils. These methods provide a reliable and removable joint, making them appropriate for applications requiring disassembly. In conclusion, different joining methods, including welding, brazing, soldering, and mechanical fastening, can be used with aluminum coils. The choice depends on factors like the application, alloy type, and desired joint properties.

- Q:What are aluminum coils?
- Aluminum coils are long, flat strips of aluminum that have been rolled up into a cylindrical shape. They are commonly used in various industries, including automotive, construction, and HVAC, for their excellent heat conductivity and corrosion resistance properties. These coils can be further processed and fabricated into different products such as roofing materials, heat exchangers, and electrical wiring.
- Q:How are aluminum coils made?
- Continuous casting and rolling is the method utilized for the production of aluminum coils. The process commences by melting aluminum ingots or scrap in a furnace. After reaching the desired temperature, the molten aluminum is transferred to a holding furnace. Subsequently, the molten aluminum is continuously cast into a solidified strip, which is then passed through a series of rolling mills. The rolling mills exert pressure on the aluminum strip, reducing its thickness while increasing its length. This procedure is repeated multiple times until the desired thickness and width are attained. Simultaneously, the aluminum strip is cooled and lubricated during the rolling process to prevent adherence to the rollers and enhance the surface finish. Once the rolling is complete, the aluminum strip is coiled to form a continuous sheet of aluminum coil. To ensure stability during transportation and storage, the coils are typically wound tightly, minimizing any air gaps. At this stage, the coils can undergo further processes such as annealing. This involves heating the coils and gradually cooling them to enhance their mechanical properties, making them more suitable for specific applications. In summary, the production of aluminum coils comprises a combination of melting, casting, rolling, and coiling procedures. The ultimate goal is to generate top-quality coils with the desired dimensions and properties.
