Ferrite magnets are sintered permanent magnets and are one of the most widely used magnets with low cost. Ferrite magnets are mainly made of SrO and Fe2O3 as the main raw materials through a vitrified sintering process. These magnets are corrosion resistant and do not require surface plating. They can be made in cylindrical, circular, square and tile shapes.
Our ferrite products have stable performance and excellent quality,mainly used in various motors, household appliances and electro-acoustic products. Our magnets are well received by customers at home and abroad.
