Cold rolling is a metalworking process where metal sheets or strips are passed through rollers at room temperature. This technique reduces the thickness of the metal while improving its surface finish and strength. The process is commonly used for materials like steel and aluminum. During cold rolling, the metal undergoes plastic deformation, which enhances its mechanical properties. The result is a more durable and precise product, often used in various applications, including automotive parts and construction materials. Cold rolling is favored for its ability to produce tight tolerances and a smooth surface without the need for additional heating.
