<p>A solder alloy which does not exert adverse influences on the environment and has soldering properties equal to those of conventional Pb-Sn solder alloys; and a soldered joint made with the solder alloy. The solder alloy consists of 4.0 to 10.0 wt.% zinc, 1.0 to 15.0 wt.% indium, 0.0020 to 0.0100 wt.% aluminum, and tin and unavoidable impurities as the remainder. The soldered joint made with the solder alloy is useful in electrical/electronic appliances.</p> |
