Sintered Ferrite Magnet Material Specifications & Technical Data

+Contact us

 

Sintered ferrite (ceramic) magnets are iron oxide–based permanent magnets that provide a reliable and cost-effective magnetic solution for high-volume applications. These materials typically offer energy products ranging from approximately 1 to 5.6 MGOe and are known for their excellent resistance to corrosion, strong resistance to demagnetization, and stable magnetic performance across a wide range of operating conditions.

Because ferrite magnets are economical and require little to no protective coating, they are widely used in electric motors, generators, speakers, sensors, and other industrial magnetic assemblies where magnet size is less critical than durability and cost efficiency.

Please refer to the table below for sintered ferrite material specifications.
