What is an alloy?

An alloy is best defined as a mixture of pure metals or a combination of a metal with one or more additional substances, which can also be metals or non-metals. The purpose of creating an alloy is to enhance specific properties such as strength, corrosion resistance, and ductility, which are often superior to those of the individual metals alone.

For example, steel is an alloy made primarily of iron mixed with carbon and other elements, resulting in a material that is much stronger and more versatile than pure iron. This increased performance is why alloys are widely used in various applications, including construction, automotive, and manufacturing industries.

Understanding the nature of alloys is essential in the study of materials, as it underscores the engineering principles behind creating stronger and more functional materials through the combination of different elements.
