Strontium Ferrite Magnetic powder

Sintered hard ferrite magnets are manufactured by a die pressing followed by sintering process which allows economic production of components in a varied array. Sintered hard ferrite magnets are manufactured by a die pressing followed by sintering process which allows economic production of components in a varied array of sizes and shapes. Ferrite magnets have excellent corrosion resistance and have normal operating capabilities between -40 °C and +250 °C.

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

Applications: •Magnetic rollers for copier and laser printer •Permanent motor magnets (rotors & other components) •Magnetic rings for aerodynamic component •Color Monitor/TV purity convergence magnet •Binders: PA6, PA12, PPS Characteristics •Binders: PA6, PA12, PPS •Can be magnetized in any direction, suitable for the radial or axial(face) multi-polar magnetized magnet. •One time forming the complex shape. •Forming the shape with the shaft or bushing one time to reduce assembly processes and improve assembly accuracy. •No surface treatment.
