Nonferrous metals are all alloys or metals that do not contain any iron. These metals are the opposite of ferrous metals, which are all metals that contain a percentage of iron. Unlike ferrous metals, nonferrous metals do not rust or oxidize.Their main advantage over ferrous materials is their malleability. They also have no iron content, giving them a higher resistance to rust. Lastly they are non-magnetic, which is important for many electronic and wiring applications.
Unlike ferrous metals, nonferrous metals are not magnetically attractive. This can be a disadvantage since it excludes this metal from any application where magnetism is necessary or is an advantage.
Nonferrous metals typically are light-weight and have limited strength capabilities. This prevents these metals from being used in any application where strength or heft is necessary. Because of this property, nonferrous metals are generally not used in industrial settings or industrial equipment. Nonferrous metals are also not typically used in decorative hardware or any types of tools or equipment.
On average, nonferrous metals cost more than ferrous metals, although the price can vary according to the metal. Industries or companies needing nonferrous metals for applications face a disadvantage compared to those companies using ferrous metals, because the cost is higher.
