Which metal is used in the galvanisation of iron in order to prevent it from rusting? Correct Answer Zinc

Zinc is used in the galvanisation of iron in order to prevent it from rusting. The layer of zinc is more reactive than iron, and hence it cuts the contact of iron with air or moisture and protects it from rusting.
