Answer the follow

Alloy is a homogeneous substance which is made after melting of two or more elements. Basically, it is a mixture of any two or more than two metals.

Characteristics of alloys:

1. Different alloys have different properties like malleability, physical appearance etc. Example, copper and tin combine to form Bronze. Bronze is a harder alloy than copper. If the physical properties of alloy can be changed but chemical properties will remain the same.

2. Alloy having compositions of elements in fixed proportions

For example: Brass is alloy of copper and tin.
