A Eutectic is a material that does not have a "pasty range" of temperature.
The melts at a certain temperature on the way up (heating) , and solidifies
at that same temperature on the way down (cooling). Impurities will alter
this condition.

Subject: [TN] Definition of Eutectic Solder
Hello,
What is actually eutectic solder? All along I have this impression that when
we talk of eutectic solder, it is refer to Sn63. However, yesterday, I
attended a course and was told that Sn96 (4% silver) is also eutectic. Can
someone enlightenment me?
Thanks and regards,
Wee Mei
