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 950°F), according to AZoM. Hot rolling prevents most or all work hardening and allows the aluminum to remain ductile.
