  Aluminium Hot and Cold Rolling | SpringerLink

  The rolling of thin aluminum foil is a very specific process and differs from conventional cold rolling. This rolling mode is reached at thicknesses below app. 70 μm. With decreasing strip thickness, the specific roll force increases, which leads to an increasing elastic work roll flattening in the contact zone.
