Ferrite Magnet Bulk Purchasing Solution
Development History of Ferrite Magnets
Permanent ferrite magnets started developing in the 1930s by Japanese scientists Yogoro Kato and Takeshi Takeshi Takei, synthesizing the first compound using iron oxide and alkaline earth metal oxides as a base. In addition, their industrialization had been made by powder metallurgy.
In the 1970s, ferrite ceramic magnets became the standard core material for speakers, miniature motors, and magnetic separators.Magnet manufacturers like TOPMAG have focused resources on local strontium ore and reached over 30,000 tons in annual production capacity, dominating the global mid- and low-end market with dark grey ring-shaped magnetic tiles and arc-shaped magnetic blocks. Until now, ferrite has remained the “cost-performance king” in the industry.

Ferrite Magnet Datasheets
Ferrite magnets are one of the most inexpensive and efficient objects to be used as material for a magnetic material that will stay magnetized forever. Because of its superior corrosion resistance, temperature stability, and magnetic properties, the ferrite magnet can maintain stable operation for a long time, even in challenging environments, like those with a very high humidity level or high temperatures. Several options are available for the ferrite magnet grades, which give the users the necessary flexibility, and, at the same time, they can offer the needed magnetism power for particular operations.
Custom ferrite magnets can also be tailored to unique specifications, further optimizing their effectiveness and reducing long-term costs in specialized applications.

Surface Treatment of Ferrite Magnets
The material’s corrosion resistance is sometimes considered when selecting a surface treatment procedure. Because of metallic composition, most magnet types, particularly neodymium, are highly susceptible to oxidation and, as a result, corrosion. When exposed to air, neodymium magnets can quickly react with moisture or oxygen, losing magnetic characteristics and causing structural damage.
Unlike neodymium magnets, ferrite magnets are formed of ceramic material, naturally providing high corrosion resistance. That means that ferrite magnets can work consistently in most environments and are less impacted by external climatic change or oxidative components in the air.
The Price Trend of Ferrite Magnets
Iron and oxides are the primary raw materials used in ferrite magnets. Therefore, price fluctuations in these materials directly affect the cost of the ferrite magnet. The chosen manufacturing process is more complicated for applications requiring great precision or high performance. Technical support and investment in extra molds or equipment are necessary.
