The raw materials of the aluminum strip are pure aluminum or aluminum alloy cast-rolled aluminum coils and hot-rolled aluminum coils, which are rolled into thin-plate aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally slit into different widths by a slitting machine according to the application. of aluminum strips.
Classification of aluminum strips
Commonly used alloy grades of aluminum strips are 1050, 1060, 1070, 1100, 3003, 3004, 5005, 5052, 8011 and so on. Commonly used states are O state and H state. O represents the soft state and H represents the hard state. After O and H, numbers can be used to express the degree of softness and hardness, and the degree of annealing.
The specific uses of aluminum strip mainly include: transformer aluminum strip (transformer aluminum foil), aluminum strip for high-frequency welding hollow aluminum strip, aluminum strip for finned radiator, aluminum strip for cable, aluminum strip for stamping, etc.
