Abstract: The work presents the possibilities to realize the dies to processing by metal forming of some metallic material with low plasticity like magnesium alloys AZ31B, AZ61B and MN150 and the aluminium alloy AlMg4.5Mn0.4. This materials are used often especially in aeronautical industry and in the automotive industry because of their low density of approximately 1.74 g/cm3. This density is about 75% lower than the density of steel, which leads to a considerable decrease of the weight of the metallic constructions. However, because of their low plasticity at room temperature, the process must be realized at temperature between 200 °C and 250 °C, range of temperature for which a considerable increase of the plasticity of the above mentioned alloys occurs without influencing the mechanical proprieties. Thereby, the metallic materials with low plasticity and light weight at the same time would possible substitute successfully conventional sheet materials.
