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.
A non-ferrous metal is any metal that does not contain iron. Most of the time non-ferrous metals are a non-magnetic metal. If a magnet does not pull to the metal you are testing, it is a probably a non-ferrous metal. Non-ferrous metals are more valuable than ferrous metals and should be separated to get the most return for your metal. A couple of popular non-ferrous metals are copper, brass, and aluminum.
