As the third alloying constituents, 0.5 to 6% of Cu, Ag, Zn, Hg, Al, Ti, Sn, Pb, Sb, Te, Cr, Mn and Ni were added alone or duplicately to the binary alloys of Mg-Cd, which contains 1 to 10% of the latter element. The Rockwell-hardness value of these alloys in the cast, annealed, quenched and aged state as well as the corrodibility against the distilled, the ordinary and the salt water were measured. The results obtained may be summarised as follows : The third constituents which harden the binary alloys most remarkably, are found to be Cu, Ni, Ag and Al, Sn, Mn, Zn, Sb and Hg harden the alloy to a certain extent, while the hardening effect of Pb and Te is very small. The alloys in the cast state show generally the highest heardeness value ; the annealing or quenching make them softer. A remarkable aging effect is found in the alloy containing Al or Zn. The addition of Ni, Cu and Ag shows a marked injurious effect on the eorrodibility of the Mg-Cd alloys. Al, Pb, Te and Sb make also the alloy corrodible. Although Sn, Zn, Mn, Hg and Ti do not improve the corrodibility of the binary alloys remarkably, the existence of these metals is at least not very harmful.
