Ferrous and non-ferrous metals are different both in chemistry and in the way they are used. There are a few key differences that can be used to distinguish between the two types. The defining difference between ferrous and non-ferrous metals is in their iron content. Both types may be pure or alloys. In general, ferrous metals contain iron. The very word ferrous comes from the Latin word for iron, ferrum.
Examples of Ferrous and Non-Ferrous Metals
A non-ferrous metal can be described as any metal, including alloys, that does not contain iron ferrite. They are more expensive than ferrous metals and have properties that include low weight, resistance to corrosion and a high level of conductivity, making them more desirable. Well known non-ferrous metals include copper, lead, zinc, aluminium, tin, nickel, gold, silver and platinum. Because non-ferrous metals are very malleable they are more suited to for use where weight is an important factor. For example, in aircraft manufacture the materials must be strong but also as light as possible.
What is the difference between ferrous and non-ferrous metals? Ferrous metals contain iron and non-ferrous metals do not. Non-ferrous metals are rarer, more valuable and resistant to corrosion, than ferrous metals. Ferrous and non-ferrous metals are both recyclable. Magnetising the iron in ferrous metals can separate ferrous and non-ferrous metals. The term ferrous is derived from the Latin word ferrum and means that the metal compound contains iron.
That means each type of ferrous and non-ferrous metal has different qualities and uses. Ferrous Metals Ferrous metals contain iron, and are known for their strength. Think steel, stainless steel, carbon steel, cast iron. Ferrous metals are used in both architectural and industrial fabrication, such as skyscrapers, bridges, vehicles, and railroads. Thanks to their magnetic properties, ferrous metals are also used in appliances and engines.

Ferrous and non-ferrous metals
They need protecting with paint, oil or a surface finish. They react to a magnet. Consequently, they do not to rust or suffer unduly from contact with moisture. They do not react to a magnet.
