  1. Alloying is a method of improving properties of a metal. We can get desired properties by this method.
  2. For example, iron is the most widely used metal. But it is never used in its pure state.
  3. This is because pure iron is very soft and stretches easily when hot.
  4. But, if it is mixed with a small amount of carbon, it becomes hard and strong.
  5. When iron is mixed with nickel and chromium we get stainless steel which will not rust.
