Description

Specification of YXC Dry Pressing Strontium Ferrite & Barium Ferrite Magnetic Materials

YXC series Strontium Dry Pressing Ferrite Magnetic Powder and Barium Dry Pressing Ferrite Magnetic Powder are suitable for producing magnets by dry pressing. According to different property requirements, such ferrite powders can be classified as isotropic and anisotropic powder. Anisotropic powder has better orientability. Products include dashboard insulations for interiors and engine compartments, motor capsule absorbers, tunnel insulation, acoustically effective heat shields, engine hood absorbers, spring-mass systems and wheel house liners.

Strontium ferrite powders have been designed to produce all grades of hard ferrites. The users will make high quality magnets by adding the provided additives into the powders. Our highly automatic instruments and strict quality control system ensure that the quality is stable and reliable.

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. It can also 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.

3.Procedure Summaries of Making Magnet by Ferrite Materials

There are 6 types of dry pressing ferrite powder for customers: YXC-C1, YXC-C2T, YXC-C3T, YXC-C1, YXC-C2, YXC-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℃ to 1270℃. Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill. (Due to the actual sintering temperature measured by various suppliers instruments are not the same, we can only provide sintering temperature of 1220℃-1270℃ for reference.)
