- noun a mixture that has the lowest freezing point of any combination of its constituents
- A mixture of two or more substances which has the lowest possible melting point. That is, the proportion of each component is such, so that any other overall combination of such substances would have a higher melting point. Low-melting point alloys are usually eutectic. Used, for instance, in solders, contacts, and semiconductors. Also called eutectic (2).
