What is the Aluminum Rolling Process? A 3-Step Overview
Cold rolling hardens and strengthens the aluminum by changing its microstructure, but it makes the metal more brittle. If the mill heats the aluminum, this process is called hot working. The specific temperature range for hot working varies by alloy. For example, 3003 aluminum is hot worked at between 260 to 510°C (500 to …
