Alloy vs. Intermetallic Compound — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on November 16, 2023
An Alloy is a mixture of metals or a metal and another element, while an Intermetallic Compound is a solid-state compound of two or more metals with a defined stoichiometry.

Key Differences
Alloy and Intermetallic Compound are both products of combining two or more metals, but they have distinct differences in composition and properties. An Alloy is a blend where the combined metals (or a metal and another element) retain some of their individual properties. On the other hand, an Intermetallic Compound forms when two or more metals combine in specific ratios, resulting in a compound with unique properties, different from its parent metals.
Alloys are created to harness the best properties of its constituent metals. By mixing metals in varying proportions, one can get an Alloy with desired characteristics like increased strength, improved corrosion resistance, or better malleability. In contrast, Intermetallic Compounds are usually characterized by ordered structures and are more brittle than their parent metals. They have well-defined electron valencies and stoichiometry.
In the industry, Alloys are immensely popular because of their customizable properties. Examples include steel (an alloy of iron and carbon) and bronze (an alloy of copper and tin). Intermetallic Compounds, however, are often seen in applications requiring specific properties like high temperature stability or certain electronic characteristics.
To differentiate based on formation, Alloys can form in any proportion, and their constituent metals may or may not be soluble in each other in the solid-state. In the case of Intermetallic Compounds, they form in specific atomic ratios, often displaying a defined crystal structure.
Summing up, while both Alloy and Intermetallic Compound involve the combination of metals, their formation, properties, and applications can vary significantly. An alloy is a blend with varying compositions, while an Intermetallic Compound has a defined composition and distinct properties.
