Due to its high-coercive property, there is a smaller chance of demagnetization, and they are suitable for being used in flat forms. The magnets are produced by pressing a fine-powder of ferric oxide in a mold and heated in a furnace at approximately 1200 degrees Celsius. They are resistant to corrosion and fit for mass production. Ferrite magnets can be classified into two categories: Anisotropic Ferrite and Isotropic Ferrite.
Characteristics:
A steady supply of raw material can be ensured at an inexpensive price-setting.
High coerciveness makes them less likely to demagnetize.
Similar to other ceramics ferrite magnets are brittle, but since they are made by molding powdered ferric oxide they are fit for mass production.
With specific gravity of 4.8g/cm3, these magnets can be much lighter compared to other magnetic products.
Able to place 2-10 poles on a flat surface. Also possible to magnetize multi-poles along the circumference of the magnet, thus more demands are coming in for applications in meters and motors.
Used as materials to make rubber magnets and plastic magnets.
Application
Ferrite magnets are used in various products, such as device for electrical instruments, automobile motors and generators, stationery products, household appliances, and healthcare equipments.
