Specification of YXC Dry Pressing Strontium Ferrite Magnetic Materials

YXC series Strontium Dry Pressing Ferrite Magnetic Powders are suitable for producing magnets by dry pressing. According to the requirement, such products can be classified as isotropic powder and anisotropic powder, anisotropic powder has better orientability. The strict quality control system ensures that the quality is stable and reliable.

3. Procedure Summaries

There are 6 types of dry pressing ferrite powder for customers: YXC-C1, YXC-C2T, YXC-C3T, YXC-C1, YXC-C2. The procedure summaries for making magnet are as follows:

The necessary secondary additives have been added into the powder during the grinding process. Customers only need to 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 orientaton

Please take care of the cleaning of the equipments. Any other materials and impurity should mot 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 between 1220 °C and 1270 °C. Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill
