What are cold rolled aluminum coils and hot rolled aluminium coils, what are their respective features?The difference between hot rolling and cold rolling is that cold rolling is rolled at recrystallization temperature and hot rolling is above the recrystallization temperature.Each has its advantages and disadvantages.Cold rolling mainly deals with non thermal strengthening of sheet metal. Generally, the surface requirement is relatively high, and the ultra-thin materials such as single zero foil, double zero foil and so on can only be rolled by cold rolling.Relatively hot rolling is the first to provide billets for cold rolling. Secondly, many materials require high corrosion resistance, fatigue resistance, plasticity and so on, which require hot rolling.Other related question
