An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.[1] An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure.
Mixture; Metal; Element; Crystal. In its scientific usage, the term metal means a metallic element. An alloy is a mixture or solid solution composed of a metal and another element. But in everyday language, we often use the word metal to describe what an alloy is. That is because a mixture of metallic elements is called an alloy. Iron is a metal element. Steel is a mixture of iron with other elements such as carbon, nickel, chromium, etc. and so is an alloy. An alloy is a mixture of either pure or relatively pure chemical elements, forming an impure substance retaining the characteristics of a metal. Alloy constituents are usually measured by mass.
