Aluminum strips are made through a series of processes starting with the production of aluminum ingots. The ingots are heated and then rolled into thin sheets in a hot rolling mill. This process reduces the thickness of the aluminum and elongates it into a strip. The hot-rolled strips are then cooled and may undergo further cold rolling to achieve the desired thickness and hardness. After rolling, the strips may be annealed to improve their ductility and strength. The final step includes cutting the strips to the required length and packaging them for distribution. This process ensures that aluminum strips have the desired properties for various applications such as construction, automotive, and aerospace industries.
