Aluminum Sheet Production: General Principles of Cold

Cold rolling is a rolling process which is occurred at room temperature where the material shows strain hardening. Although it is named as “cold” rolling, the material is heated up by deformation to approximately 100°C and a high amount of coolant is used during the process in order to have a thermal equilibrium [2]. Cold rolling, as its expected to be,
