Recently the tough solders melting at the low temperature are becoming more and more necessary in order to diminish the bad effects on the base metals brazed in high temperature soldering operation. The authors studied the binary or ternary alloys composed of Cd-Zn and Cd-Zn-Ag. The results obtained are as follows. Among the binary alloys melting in the range of 250∿450℃, the eutectic solder composed of Cd-Zn containing about 17.4% Zn possesses the best toughness and highest strength of all the other alloys. The mechanical properties are influenced adversely by the deviation of Zn % from the eutectic points. Moreover, Ag as the third element is alloyed into the Cd-Zn eutectic solders for the purpose of obtaining the higher strength. The solid solution limit 3% Ag and 6% Ag corresponding to the compound Ag Zn give the best toughness and the highest tensile strength respectively.
