Strontium Ferrite Dry Pressing Magnetic Powders
Dry Pressing Strontium Ferrite Powder Specification
Strontium Dry Pressing Ferrite Magnetic Powders and Barium Dry Pressing Ferrite Magnetic Powders are suitable for producing magnets by dry pressing. According to the requirement, such ferrite powders can be classified as isotropic powder and anisotropic powder , anisotropic powder has better orientability. Barium ferrite powder is used in the manufacture of bonded magnets. They have good compatibility with different kinds of synthetic materials such as Plastics, Polyvinyl Chloride and Rubber etc. Barium Ferrite Powder can be used for making Bonded Ferrite magnets by calendaring, extruding and injection molding. The strict quality control system ensures that the quality is stable and reliable.

There are 6 types of dry pressing ferrite powder for customers: PXC-C1, PXC-C2T, PXC-C3T, PXC-C1, PXC-C2, PXC-C3. The procedure summaries for making magnet are as follows:
- The necessary secondary additives have been added into the ferrite powder during the grinding process. Customers shall only add proper quantity of binders and lubricants. The powder must pass through 120 mesh sieve before pressing, so as binders to be uniformly distributed for better orientation.
- Please take care of the cleaning of the equipments. Any other materials and impurity should not be mixed into the powder.
- During pressing, the pressure required is >=5000N/cm2, and the magnetic field density is >7000 Oe (560KA/m).
- The sintering temperature for reference is 1220 Deg.C to 1270 Deg.C. Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill.
