Eutectic alloy

An eutectic alloy melts as well as solidifies at the same, exactly defined temperature. This melting resp. solidification point is the lowest in the alloy system. This is important for industrial applications, since the liquid solder will solidify quickly at the solder joint. At the same time, the heat input into the assembly is the lowest due to the lowest melting temperature. Some typical eutectic alloys are Sn37Pb, SnCu0,7, SnAg3,5,
