- Resistant to demagnetisation and corrosion without any extra coating.
Also known as ceramic magnets, ferrite magnets offer excellent value for money when pull strength is not the most important factor. They have a high resistance to corrosion and demagnetisation and can operate in temperatures up to 180 degrees Celsius. Ring magnets are made specifically for loudspeaker systems and their sizes have evolved with demand from this market. However, they are also commonly used in magnetic rollers for separating applications and in the printing industry. They are also a vital component found in fast running conveyor systems in many manufacturing plants dealing with ferrous material.
