An alloy is a mixture or metallic solid
solution composed of two or
more elements .Alloys usually have
different properties from those of the
component elements.

Why Alloys ARE USED
•To increase hardness of metals.•To make metals more resistant to attack by chemicals.•To change the properties of metals in other ways.
