As ferrite magnets, also known as ceramic magnets, are made from oxides of iron they do not corrode when immersed in water (even saltwater) or exposed to moisture. They are even resistant against solvents, weak acids, lubricants, salts and gasses. This is just one of the characteristics that make ferrite magnets really popular for many applications.
Did you know? Ferrite magnets have great corrosion-resistant properties – they can even be immersed in water or exposed to weak acid without corroding.
Because they are corrosion-resistant they can usually be used without any additional coating and will last a long time, generally exceeding the lifecycle of the application they are used in.
Of course, for specialist applications such as medical instruments, ferrite magnets can be coated to ensure any dust from the magnet is locked in. Ferrite magnets may also be coated to disguise their raw dark-grey colour. Typical coatings include:
With the right adhesive, magnetic and non-magnetic material can be stuck to other surfaces. Clean and grease free services provide best bonding surface. At first4magnets.com we recommend the following adhesives for use with our neodymium magnets.
