Although this represents a relatively recent development in the industry, the composite multilayer sheets are currently encountered in almost all industrial domains, due to the density, mechanical strength and energy absorption properties that are higher than those of the blanks realised from a single material. These materials are useful especially in domains such a the automotive industry, where the vehicles must fulfil simultaneously conditions of increased passenger safety, increased comfort, increase of the loading capacity in conditions of a reduced energy consumption. First of all the paper shows the types of multilayer sheets and their areas and areas of use, then the paper analyzes the experimental results for an example of such a sheets namely bimetallic tables. The materials are subjected to tensile testing and we are determined limit deformation curves. The experimental result of incremental forming on a CNC milling machine bimetallic sheet is also presented.
