Aluminum coil is a metal sheet, which is melted from aluminum ingots and added with different alloys, and processed through casting, hot rolling, cold rolling, annealing, cross-cutting and other processes. It has the advantages of low density, light weight, easy handling, strengthening, plasticity, easy processing, corrosion resistance, no low-temperature brittleness, good electrical and thermal conductivity, sound absorption, nuclear radiation resistance, beautiful appearance and re-processable surface. Therefore, it is widely used in various industries, and the usage is growing at about 7% every year.
Character of Aluminum Coil:
- Easy to handle and strengthenable: Various processing can be performed, such as cutting, bending, drilling, etc., to meet different design needs. In addition, it can enhance its physical and mechanical properties, such as hardness and corrosion resistance, by adding other alloying elements.
- Plasticity and easy processing: It has good plasticity at high temperatures and can be made into parts of various shapes and sizes through stamping, stretching, extrusion and other processes. In addition, aluminum coils can also be further processed through processing equipment, such as being made into complex parts or components.
- Corrosion resistance: It has good corrosion resistance, is not easy to rust, and can be used for a long time in various environments. This characteristic makes aluminum coils particularly suitable in corrosive environments such as outdoor applications and coastal areas.
- No low-temperature brittleness: No brittle fracture will occur in low-temperature environments, and it has good low-temperature toughness. This characteristic enables aluminum coils to maintain stable performance in extremely cold areas or low-temperature environments.
- Good electrical and thermal conductivity: Aluminum is a good electrical and thermal conductive material and can be used to make various power and heat transmission lines. For example, in the construction sector, aluminum coils can be used to make power cables and radiators.
