Ferrite magnets offer a low cost and corrosion free performance that last. Ferrite magnets are extremely popular due to their characteristics. Being made from oxides of iron, they simply do not corrode when placed in water. They are therefore regarded as corrosion free. For long term performance, they are superb; if looked after they can exceed most products lifecycles.

Ferrite Magnets resist chemical attacks from many of the alkaline solutions, dilute acids, organic solvents, and some hydroxides. They are fine for use in salt water conditions (no corrosion issues at all). 

They do not need a coating but have been known to be coated only in specialist applications where any ferrite surface dust is not wanted. An example where coating may be required is in medical applications.

Ferrite magnets are naturally a darker grey colour and are often referred to as having a "pencil lead" colour.
