It should say 'Fe'. 'Fe' as found in 'fe'rrous. Ferrous things contain iron because the metal 'iron' is represented by the symbol Fe. Something non-ferrous is devoid of iron. Thus, a non-ferrous metal is a metal (or a mixture of two or more metals) that contains inconsequential amounts or no amount of iron. They are therefore nonmagnetic and don't rust like ferrous metals do.
Some examples of non-ferrous metals are copper, zinc, nickel, brass, aluminum, and lead. They have very different properties from one another and are used for a variety of applications. What all non-ferrous metals have in common is they are not magnetic because they do not contain iron.
