An alloy is a mixture of metals or a mixture of a metal and another element.Alloys are defined by metallic bonding character.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.he term alloy is used to describe a mixture of atoms in which the primary constituent is a metal.

Brass is an example of a mixture of two elements: copper and zinc. It can contain as little as 10%, or as much as 45%, zinc. Another difference between compounds and mixtures of elements is the ease with which the elements can be separated.xample: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid. Hydrogen and oxygen, on the other hand, cannot be decomposed into simpler substances. They are therefore the elementary, or simplest, chemical substances-elements.
