An alloy results when an additional element is introduced into the metalic crystal. Metal+ metal = alloy (zinc + copper + carbon = brass)
Would carbon not be a product of the reaction?
There are many ways they change.

metals
Because alloys often have better properties than their parent metals. Stronger, rust resistant etc
An alloy is a type of metal (specifically, it's a solid solution of dissimilar metals). All alloys are metal, but not all metals are alloys ... pure metals (pure gold or pure copper, for example) are not alloys.
Alloys are "mixtures" of metals or non-metals in metals. They are developed to create new characteristics of the metals. Carbon (and other things) added to iron makes steel. Precise mixtures makes different sorts of steel alloy. Steel is stronger than iron and can have many characteristics which give superior properties for specific purposes. There is a virtual infinite number of alloys which could be made. Not all will have useful characteristics.
Alloys have improved mechanical properties, hardness, resistance to corrosion, resistance to heating, stable crystalline structure etc. compared with pure metals.
metals
they can be melted, mixed with other metals(alloys)
By developing different alloys with better properties.
Alloys have useful properties that are not found in the pure metals from which they are mixed. You can make alloys that are stronger, lighter, more corrosion resistant, and so forth, as compared to pure metals at a comparable price range.
Alloys have better properties than single metals.

Alloys are sometimes more useful than pure metals because alloys are stronger - or tougher (toughness is resistance to fracture). Pure metals tend to be softer than alloys and therefore tend to get dented, scratched, or broken/fractured more easily. Alloys are often lower cost than pure metals but not necessarily so. As an example, stainless steel is more expensive than pure iron.
metals :) ~_~ ^_^ @_@ A_A !_! *_* ^-^im kinda board but the answer is metal hoped it helped.
Extraction of metals from its ores and formation of ores. Studying their properties, their alloys,refining of ores.
Many alloys are made by melting metals and mixing them together in carefully measured amounts.
