What is the Aluminum Rolling Process? A 3-Step Overview - Gabrian

If they do not heat the aluminum before rolling, the aluminum will be cold worked. 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.
