Explain why metals are often used in the form of alloys?

--- End quote ---

Iron to stainless steel> does not rust
Alloys are stronger/harder
Can be used in specific proportion to create 'customised' properties :: Alloy of Al(Zn+Mg+cu)-Light weight and strong
Alloy-solder-to lower melting pt.
Brass-easy to shape
Cupro-nickel-Usually cheaper than silver(used as coins)

any more would be appreciated..

@Vin  we don't specifically need to know all the characteristics for alloys.

Yes, absolutely. But our teacher made us learn us all so I know most of them. ;D
