1. relating to or denoting a mixture of substances (especially metals or salts) that has the lowest melting point of any possible combination of those substances
Usage: technical; chemistry

1. a eutectic mixture or alloy; a combination of substances that melts and solidifies at a single, fixed temperature lower than the melting points of the individual components
Usage: technical; chemistry

Examples

• The eutectic point of lead and tin occurs at 183°C.
• A eutectic alloy of copper and silver has a lower melting point than either metal alone.
• Solder is often a eutectic mixture designed to melt at a specific, predictable temperature.
• The eutectic composition allows the material to solidify uniformly without phase separation.
• Engineers select eutectic alloys for applications requiring precise melting behavior.
• The eutectic system of salt and ice is used in laboratory freezing procedures.
