Question
Give the classification of alloys with examples.
Advertisements
Solution
Alloys are classified into ferrous and non-ferrous.
- Ferrous alloys: Ferrous alloys have atoms of other elements distributed randomly in atoms of iron in the mixture. As the percentage of iron is more, they are termed ferrous alloys eg. nickel steel, chromium steel, stainless steel, etc.
- Non-ferrous alloys: Non-ferrous alloys are formed by mixing atoms of transition metal other than iron with a non-transition element. eg. brass, which is an alloy of copper and zinc.
