Question

What is an alloy? Why are alloys made?

Answer 1

Part I - Definition

Alloy is a homogenous mixture of two or more two metals or non-metals.

For example - Brass is an alloy of zinc $\left(\mathrm{Zn}\right)$and $\left(\mathrm{Cu}\right)$ ).

Part II - Reason for making alloys

• Metals or non-metals do not have enough physical strength and are corroded easily.
• Hence alloys are made and they have enhanced physical properties than metals or non-metals.

For example - Stainless steel is used in place of iron because iron rust easily but stainless steel is rust-resistant.
