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.
Ferrous means that the metal has iron content which in most cases makes it magnetic and nonferrous means it doesn't have iron in it. An example of a ferrous metal is mild steel, also known as low carbon steel.errous means that the metal has iron content which in most cases makes it magnetic and nonferrous means it doesn't have iron in it.
