* Definition: Ferrous metals are metals that contain iron as a major component.

* Characteristics:

* Strong and durable

* Magnetic (except for some stainless steels)

* Susceptible to rust and corrosion

* Examples:

* Steel (iron alloyed with carbon)

* Cast iron

* Wrought iron

Non-Ferrous Metals

* Definition: Non-ferrous metals are metals that do not contain iron as a major component.

* Characteristics:

* Often lighter and more corrosion-resistant than ferrous metals

* May have unique properties, such as conductivity or malleability

* Examples:

* Aluminum

* Copper

* Gold

* Silver

* Titanium

* Zinc

Key Difference: The presence or absence of iron is the defining characteristic that distinguishes ferrous from non-ferrous metals.

Note: Some alloys, like stainless steel, can be considered both ferrous and non-ferrous depending on the specific composition and properties. However, they are generally classified as ferrous because they contain iron as a major component.
