PROBLEM TO BE SOLVED: To provide a solder alloy for joining Sn-Zn aluminum, which improves solderability by suppressing oxidation of the solder alloy.SOLUTION: In a solder alloy for joining aluminum, 10.0-30.0 wt.% of Zn and 0.1-3.0 wt.% of Al are added to Sn. Ag, Sb, Ni, Co, Fe, Cr and the like can also be added as strength improving elements, Bi, In and the like can also be added as melting point lowering elements, or P, Ga, Ge and the like can also be added as antioxidation elements. |
