The two different … Alloys Eutectic alloys have two or more materials and have a eutectic composition. When a non-eutectic alloy solidifies, its components solidify at different temperatures, exhibiting a plastic melting range. Conversely, when a well-mixed, eutectic alloy melts, it does so at a single, sharp temperature. The various phase … See more A eutectic system or eutectic mixture is a homogeneous mixture that has a melting point lower than those of the constituents.
