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.
The biggest difference between ferrous and non-ferrous scrap metal is that while ferrous scrap metal may contain iron, non-ferrous metal does not. One of the most widely-recycled scrap metals, steel, is an example of a ferrous scrap metal. Other examples of ferrous scrap metal include light & cast iron. Ferrous metals are usually much more bulky than non-ferrous metals.
