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.
Copper, brass, and bronze alloys are non-ferrous metals with excellent electrical and thermal conductivity as well as good corrosion resistance, ductility, and strength. Copper is a reddish orange, soft, and malleable (low hardness) metal that is a good conductor of heat and electricity.
