1. Plural of eutectic; mixtures of two or more substances that melt and solidify at a lower temperature than any other combination of the same substances.
Usage: technical; chemistry

Examples

• Eutectics are commonly used in soldering because they have lower melting points than pure metals.
• The study of eutectics is essential in materials science and metallurgy.
• Lead-tin eutectics were historically important in electronics manufacturing.
• Researchers examined various eutectics to find the best composition for the alloy.
• Eutectics form when two elements reach their optimal mixing ratio for minimum melting temperature.
