Key Differences
Metals are pure substances found naturally in the Earth's crust, known for their distinct shiny appearance and excellent thermal and electrical conductivity. On the other hand, alloys are combinations of two or more elements, typically metals, deliberately created to improve characteristics like strength, ductility, and resistance to corrosion.
While metals such as gold, silver, and copper have been used in their pure form for thousands of years, alloys like steel (iron and carbon) and bronze (copper and tin) were developed to overcome the limitations of pure metals. For instance, pure iron is relatively soft and rusts quickly, whereas adding carbon to make steel increases both its hardness and durability.
Metals generally exhibit a high melting point and density. On the other hand, alloys can have varied melting points and densities depending on the proportions and types of elements mixed, offering more versatility for specific applications.
The electrical conductivity of metals is typically very high, making them excellent conductors of electricity. In contrast, alloys often have reduced conductivity, a trade-off made to gain other desirable properties like enhanced strength or resistance to wear.
Pure metals can be too malleable or ductile for certain uses. Conversely, alloys, by combining metals with non-metallic elements, can be engineered to have greater hardness or stiffness, broadening their utility across industries like aerospace and construction.
