The raw materials of aluminum strip are pure aluminum or aluminum alloy cast-rolled aluminum coil, hot rolled aluminum coil, rolled into thin aluminum coil of different thickness and width by cold rolling machine, and then according to the purpose, longitudinally cut into aluminum strip of different width
Common aluminum strip alloy grades are 1050, 1060, 1070, 1100, 3003, 3004, 5005, 5052, 8011 and so on. The common states are O state and H state, etc. O for soft state, H for hard state. O and H can be followed by a number to indicate the degree of hardness, and annealing degree
