WebEutectic alloys aren’t formed by all binary alloys. Because the valence electrons are incompatible with super-lattice formation, gold-silver does not form a eutectoid. Both academically and technologically, eutectic alloys are extremely important. These systems have a lower melting point than pure elements and are more fluid, making them ...

A eutectic system or eutectic mixture is a homogeneous mixture that has a melting point lower than those of the constituents. The lowest possible melting point over all of the mixing ratios of the constituents is called the eutectic temperature. On a phase diagram, the eutectic temperature is seen as the eutectic point (see plot on the right).
