Hint: An alloy is a uniform mixture. It is made up of two or more chemical elements, of which at least one is a metal. Most alloys are made by melting the metals, mixing them while they are liquid to form a solution, then leaving them to cool and turn solid again.

Complete answer:
Almost all metals are used as alloys, that is, mixtures of several elements because these have properties superior to pure metals. Alloying is done for many reasons, typically to increase strength, increase corrosion resistance, or reduce costs.
Alloys are made to enhance the hardness of a metal. An alloy is harder than its components. Metals in pure form are chemically reactive and can be easily corroded by the surrounding atmospheric gases and moisture. Alloying a metal increases the inertness of the metal, which, in turn, increases corrosion resistance.
People also make and use alloys because metals don't have exactly the right properties for a particular job. Iron is a great building material but steel is stronger, harder, and rustproof.
Alloys are, for example, generally harder than pure metals. They are made up of atoms of different sizes, rather than being uniform. Alloys also tend to have better corrosion resistance than pure metals, and are more versatile for manipulating into different forms.

Remember steel is technically an alloy rather than a metal, it is the strongest alloy currently available. Researchers are attempting to create stronger combinations of elements, but for now, steel mixed with a few other elements is considered the strongest.
