In the ''Cold Roll-Cladding'' process the bond between the contact and carriermaterial is achieved by cold deformation of > 50% in one rolling pass ''(Fig. 3.4)''.The high plastic deformation causes cold welding in the boundary layer betweenthe two materials. To increase the quality and strength of the bond a subsequentdiffusion annealing is performed in most cases. This process is most suitable forclad semi-finished strips with thin contact material layers (> ≥ 2 μm) and large striplength (> 100 m).
