What is the difference between a ferrous metal and a non-ferrous metal? - Leaving Cert Engineering - Question d - 2009

A ferrous metal is defined as any metal that contains iron as a principal component. Examples of ferrous metals include steel and cast iron. Ferrous metals are known for their magnetic properties and are typically strong and durable, making them suitable for construction and industrial use.

In contrast, a non-ferrous metal does not contain iron in significant amounts. This category includes metals such as aluminum, copper, lead, and zinc. Non-ferrous metals are generally more resistant to corrosion and have lower densities than ferrous metals, making them ideal for applications where weight and resistance to rust are crucial.
