Taking the results of test descried in the 1st report (This Journal, 21, 1935, 85.) into consideration, 0.5∿2% of Na, Ca, Sr, Ba, Zn, Hg, B, Ti, Zr, Sn, As, Sb, Bi, Se, Te, or Mn has been added alone or duplicately to the magnesium or to the Mg-Cd alloy, containing 3% of the latter element. The results of the corrosion-test of these alloys against 2.5% salt water have shown that (a) the ternary or quaternary alloys containing 3% of Cd and 0.5∿1% of Ca, Sr, Ba, Hg, As, Se or Te, and (b) the binary alloys containing 0.5∿1% of Ca, Sr, Ba, and Hg, (especially in the quenched state) have comparatively high resistance against corrosion. The electrical and mechanical properties of the alloys containing Cd, Ca, Sr, Ba, Hg or As have been studied in detail, and found that the addition of Ca, Sr or Ba lowers the electrical resistivity, hardens the alloys and improves the mechanical properties remarkablly. The suitable temperature for rolling of the Mg-Ca and Mg-Cd-Ca alloys has also been determined.
