Materials with a good level of Malleability

It is known as lamination or laminate (sometimes also called rolling) the industrial process by which the thickness of a sheet of metal or similar materials is reduced with the application of pressure through the use of different processes, such as ring lamination or profiling. Therefore, this process is applied on materials with a good level of malleability. Laminate can be cold or hot. Hot-rolling is the one that is made at a much higher temperature than the recrystallization that the metal has.
