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.
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.

People mix pure metals with other metals to create alloys that have improved properties, such as increased strength, durability, or resistance to corrosion. Alloys can also provide cost savings by using less of the more expensive pure metal while still achieving the desired characteristics.

Alloys (mixtures of metals and other elements) have different properties form pure metals.Two examples:An alloy of carbon & iron males steel which can be much harder than ironAn alloy of copper and tin makes bronze which is harder and more corrosion resistant than either of the pure metals
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 harder than the components.

A pure metal is found in nature. An alloy is a combination of metals. Alloys are better because some metals react with air and water yet Alloys dont react as much. This is why car wheels are made of Alloys so that they dont react with air or water. Alloys are simply a mix of two different metals. After being mixed they have different and better characteristics such as stainless steel. Alloys are a special type of metal.
A pure metal contains only one metal while an alloy is a mixture of two or more 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.

When metals react with other metals, they can form metal alloys. These alloys have different properties compared to the pure metals and are often stronger and more resistant to corrosion. Mixing metals together can also alter their physical and chemical properties.
Any metal that is not pure (combination of two or more metals) is known as an alloy. For a list of alloys see: http://en.wikipedia.org/wiki/List_of_alloys

Alloys allow certain metals to be stronger, or lighter, or both
Metals are a class of elements. A pure metal is an element. Some metals are alloys, which mean they have more than one metal or element in them. The metal bronze is made of two elements, the metal tin and the metal copper.
