The most common way of classifying them is by their iron content. When a metal contains iron, it is known as a ferrous metal. The iron imparts magnetic properties to the material and also makes them prone to corrosion. Metals that do not have any iron content are non-ferrous metals. These metals do not possess any magnetic properties.
