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. Zintl phases are also sometimes considered alloys depending on bond types (see also: Van Arkel-Ketelaar triangle for information on classifying bonding in binary compounds). 

An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.
What is an alloy?
are they pure?
and what does that form?
Is there another name for it?
is it a solid?
When are two or more solutions used?
What happens in the single phase?
Are the added impurities desirable?
any benefit?
What is a primary metal?
What could its name be of/
Do the others need to be metal?
are they soluble?
what do they dissolve into?
is primary and base metal the same?
Does one element have to be metal to make and alloy?
Is wrought iron and impure metal?
