Alloys have simply been studied to have better properties (strength, higher/lower melting point, low density, resistance to corrosion etc...) to fit better the uses they have been designed for.
Alloys are developed specifically to have advantages over homogenous metals. More strength, more flexibility, lighter weight, reduced cost in manufacturing, higher heat tolerances, a combination of things, etc.
The alloys can have better properties(stronger, easier to machine..) than the pure materials
There are many reasons depending on the alloy application - lighter, stronger, wont oxidize
alloys can have a mixture of characteristics- much like hybrid plants having numerous characteristics.
Because they associates the good properties of the component metals.
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.
Alloys are not necessarily harder or stronger than pure metals. For example gallium and aluminum form an alloy that is extremely weak. Many of the alloys we know of are stronger than pure metals because those are the ones we find most useful. In most pure metals, there will be gaps in between atoms. In many alloys we fill in those gaps with some other type of atom, adding extra support.

An alloy is mixture of two or more metals. Alloys are normally harder than the metals they contain. Examples of alloys include brass, steel and bronze.
There are different properties in alloys eg brass is stronger than bronze, steel is stronger than iron, more rust proof, they have different color, eg rose gold, different melting temperatures etc
Alloys are more durable than normal metals, this is because its lots of metals together. Its also cheaper to produce than some other metals.
Alloys are usually tougher than the separate ingredient metals, but not always.

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.
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 contain metals but also nonmetals.
alloys
Alloys are harder than the components.
Because alloys often have better properties than their parent metals. Stronger, rust resistant etc
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.
