Alloys are sometimes more useful than pure metals because alloys tend to be stronger though not necessarily. Pure metals tend to be softer than alloys, which are a mix of two or more metals, and therefore get dented, scratched, or broken more easily. Gold used in jewelry is a good example. Metal alloys have different structural and behavioral characteristics than pure metals. Alloying a metal also gives it a different appearance.

In some cases alloys may result in a lighter metal without sacrificing other necessary characteristics. They may also be more cost effective.
