4. Conclusion Magnesium is the lightest of all engineering metals and mainly with respect to the strong actual tendency to produce light weight car-bodies, there is nowadays great interest in developing and application magnesium product also in the automotive. Comparison of density and Young´s Modulus for selected materials is shown in Figure 3, where DX54 means deep-drawing steel, MS martensitic steel, AA6016 aluminium alloy, AZ31 magnesium alloy (see Table 2) and CFRP is carbon fibre reinforced polymer (here are values taken as the most typical ones). However, there are quite strict limitations, which restrain wider utilization of magnesium alloys (arising mostly from its hexagonal close-packed crystal lattice) and that have to be taken into account at processing magnesium alloys. On the other hand, magnesium and its alloys are still at development and represent promising materials to found (mostly in the automotive industry) quite more and more applications possibilities.
