Abstract (en)

[origin: DE19915238A1] Magnesium alloy contains traces of less than 1.8 (wt.%) cadmium, 0.1 Cu, up to 0.05 Fe, up to 0.005 Ni and 0.5-20 Li. The alloy has a tensile strength of at least 227 MPa, an energy absorbed in fracturing of at least 72 J and a breaking elongation of at least 26%. An Independent claim is also included for a process for the production of a semi-finished product comprising melting the alloy at 550-900o C, forming a molded body by casting with or without pressure, and the heat treating.
