Production of aluminum foil and aluminum coils

Aluminum foil and aluminum coils are both aluminum materials made from high-purity aluminum. Aluminiumfolie is een rolvormig materiaal met een bepaalde dikte en flexibiliteit dat wordt gemaakt van grote aluminiumrollen door middel van meerdere processen zoals snijden en gloeien. Aluminiumrollen verwijzen naar materialen die met een bepaalde breedte en dikte zijn gerold, generally with a thickness greater than 0.2mm.

The difference between aluminum foil and aluminum coil

The main differences between aluminum foil and aluminum coils are size and purpose. Aluminum foil is usually thin, generally less than 0.2mm, and is generally expressed in the form of thickness (μm) × width (mm) × length (M). The national standard stipulates that the specification range of aluminum foil is 0.006mm~0.2mm thickness and 100mm~1650mm width .
Aluminum coils are thicker, generally larger than 0.2mm. The specifications of aluminum coils mainly range from 0.15mm to 5.0mm in thickness and 50mm to 2500mm in width. Aluminum foil is mainly used for packaging (de verpakking van levensmiddelen, farmaceutische verpakking), while aluminum coils are mainly used in construction (decorative aluminum coils) and other fields.

Differences in application between aluminum foil and aluminum coils

Because aluminum materials are lightweight and easy to process, aluminum foil and aluminum coils are widely used in food, medicine, elektronica, construction and other fields. Aluminum foil is usually used for packaging, such as when grilling barbecue or roasting chicken, to prevent the food from burning or drying out;
Aluminum coils are used in the construction field as roofs, wall panels and other materials.

Advantages and Disadvantages of Aluminum Foil and Aluminum Coil

Aluminum foil and aluminum coils both have the advantages of being lightweight, easy to process, and corrosion-resistant, but they also have their own disadvantages. Bijvoorbeeld, aluminum foil is thin and easy to tear, while aluminum rolls are thicker and difficult to bend and deform. In aanvulling, since aluminum foil is used for packaging, it needs to have good sealing and toughness;
Aluminium spoelen, aan de andere kant, moeten kracht en hardheid hebben om aan de eisen van de bouwsector te voldoen.

samengevat, hoewel aluminiumfolie en aluminiumspoelen beide zijn gemaakt van zeer zuiver aluminium, ze zijn verschillend in grootte en gebruik, ze moeten dus worden geselecteerd op basis van specifieke omstandigheden in daadwerkelijke toepassingen.
