Ferrous and
Non-Ferrous MetalsTable.


All metals can be classified as either Ferrous or Non-ferrous.


These are metals which contain iron. They may have small amounts of other metals or other elements added, to give the required properties.

All ferrous metals are magnetic and give little resistance to corrosion

Non-Ferrous Metals

These are metals which do not contain any iron. They are not magnetic and are usually more resistant to corrosion than ferrous metals.

Examples are aluminium, copper, lead. zinc and tin.

See table of Non-ferrous metals for more detail.

Pure Metals

A pure metal only consists of a single element. This means that it only has one type of atom in it.

The common pure metals are:-aluminium, copper, iron, lead, zinc, tin, silver and gold.

See table of Pure Metals.


An alloy is a mixture of two or more metals. When a material is needed which requires certain properties and this does not exist in a pure metal we combine metals .

Pure white aluminium is very soft and ductile. Other elements can be added to create an aluminium alloy. This can produce a metal which is stronger than Mild Steel has improved hardness and is resistant to corrosion while still remaining light in weight.

Properties of Materials

A variety of words are used to describe materials. In order to fully understand the tables of woods, plastics and metals you will need to examine the Definition of Properties Table.

Definitions of Properties Table.

Examine the Table on Ferrous and Non-Ferrous Metals

The table shows a variety of Ferrous and Non-Ferrous metals. It also shows their uses, properties and composition.

Using the table answer the ten questions below.


1. Which type of Ferrous metal would be suitable to make tough kitchen sink units from? The surface would have to withstand shocks and wear and water flooding.

2. Name the Ferrous metal that most work-shop tools are made from?

3. Give an example of a suitable ferrous metal that may be used to make garden tools?

4. Why are the majority of wire electrical cables made from copper?

5. Name a Non-ferrous metal that is used to protect dental nurses, doctors and dentists from the harmful radiation that is given off when using X-rays?

6. How are steel corrugated roofs made water resistant?

7. Why are the panels of Land-Rovers made from Aluminium?

8. Name a Non-Ferrous metal that is suitable to make ornaments ? Name the industrial process used?

9. Give the name of the metal that is suitable to make jewellery from? Why is it a good choice?

10. Why is High tensile steel an ideal metal to make car gears from?

Lesson Task :

To be able to appreciate the great variety of Ferrous and Non-Ferrous Metals commonly used in society.
To be able to answer questions regarding the properties, uses and common forms of Metals.
