Ferrous Metals There are a lot of metals used in Engineering, however those based on iron are by far and away the most important and widely used. As a result metals are broken into 2 categories. Those that are based on Iron and those that are not. Ferrous is the Greek word for Iron and is the name given to all metals which are based on this metal. Steel is a Ferrous metal because its main constituent is Iron. A quick and easy way to tell if a metal is Ferrous or not is to use a magnet. Iron is magnetic and as a result so are all Ferrous metals, so a magnet will stick to a Ferrous metal. You can compare different Ferrous against each other in the workshop and you can find out how to do this by going to the Comparison Page.

Non-Ferrous Metals Knowing what Ferrous metals are you should be able to guess what Non Ferrous metals are. Yep... they are metals that are not based on Iron. Examples of Non Ferrous metals are, Aluminium, Brass, Copper, Lead, Tin, etc. Again you can use a magnet to tell that a metal is Non Ferrous. Naturally the magnet will not stick to a Non ferrous metal.

Alloys (Mixture of Metals) An alloy is defined as a mixture of two or more metals.
