Aluminum coils are metal strips manufactured by casting and rolling mills. Aluminum coils are widely used in electronics, packaging, construction, machinery and other fields. According to the different metal elements contained in the aluminum coil, the aluminum coil can be roughly divided into 9 categories: 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000 series.

As a substitute for steel, aluminum plate has developed rapidly in recent years, and the demand has been rising. It is widely used in a wide range of fields and is a common material in life. It is light in weight, easy to process, corrosion resistance, good conductivity, easy to recycle, easy surface treatment, good plasticity, not easy to rust, and has a long service life. It is an ideal processing material, especially in the fields of ships, refrigerators, molds, and aerospace equipment.
